Temperature Celsius The current temperature of the hard disk in degrees Celsius Count of reallocated sectors. When the hard drive finds a Reallocated Sector read/write/verification error, it marks this sector as "reallocated" Count and transfers data to a special reserved area (spare area). (SATA HDD Only) This process is also known as remapping and "reallocated" sectors are called remaps. This is why, on a modern hard disks, you can not see "bad blocks" while testing the surface - all bad blocks are hidden in reallocated sectors. However, the more sectors that are reallocated, the more a decrease (up to 10% or more) can be 49 Current Pending Sector (SATA HDD Only) Test Type (SATA HDD Only) Test Result (SATA HDD Only) Test Time (SATA HDD Only) NOTE noticed in disk read/write speeds. Current count of unstable sectors (waiting for remapping). The raw value of this attribute indicates the total number of sectors waiting for remapping. Later, when some of these sectors are read successfully, the value is decreased. If errors still occur when reading sectors, the hard drive will try to restore the data, transfer it to the reserved disk area (spare area), and mark this sector as remapped. If this attribute value remains at zero, it indicates that the quality of the corresponding surface area is low. Set short or long time to test. Result of the test. Total time of the test. If the Reallocated Sector (SATA HDD Only) Count > 32 or Current Pending Sector of a hard disk drive > 0 , for (SAS HDD) it has reported HDD status directly, the status of the disk will show “Warning”. This warning is only used to alert the system administrator that there are bad sectors on the disk, and they should replace those disks as soon as possible.

Capacity (MB) Capacity of the installed hard disks. Model Model number of the installed hard disks. Status Status of the installed hard disks. Used If this is checked, current hard disk is a part of a RAID volume. Spare If this is checked, current hard disk is designated as a spare for a RAID volume. Master RAID Check a box to designate this as the Master RAID volume. See the NOTE below for more information. Stripe Size This sets the stripe size to maximize performance of sequential files in a storage volume. Keep the 64K setting unless you require a special file storage layout in the storage volume. A larger stripe size is better for large files. Data Percentage The percentage of the RAID volume that will be used to store data. Create Press this button to configure a file system and create the RAID storage volume. To create a RAID volume, follow the steps below: 1. On the RAID Information screen, click create. 51 2. On the RAID Configuration screen, set the RAID storage space as JBOD, RAID 0, RAID 1, RAID 5, RAID 6, or RAID 10 — see Appendix C: RAID Basics for a detailed description of each. 3. Specify a RAID ID. 4. If this RAID volume is meant to be the Master RAID volume, tick the Master RAID checkbox. NOTE In a multiple RAID configuration, one RAID volume must be designated as the Master RAID volume. The Master RAID volume will store all installed modules. If the Master RAID is changed to another location (i.e. assigning volume 2 to be the Master RAID volume after volume 1 had been previously assigned), then all modules must be reinstalled. In addition, all system folders that were contained on the Master RAID volume will be invisible. Reassigning this volume to be the Master RAID will make these folders visible again. 5. Specify a stripe size — 64K is the default setting. 6. Specify the percentage allocated for user data by drag the horizontal bar. The remaining space will be made available for iSCSI. 7. Selected the file system you like to have for this RAID volume. The selection is available from ext3, XFS and ZFS. NOTE ．Select ZFS file system while snapshot is needed. It is only one ZFS file system allowed to be created per system. ．ZFS file system is only accessible by CIFS/SMB, not for AFP and NFS users. ．XFS file system is not support folder quota feature 8. Press Create to build the RAID storage volume. 52 NOTE Building a RAID volume may take time, depending on the size of hard drives and RAID mode. In general, while the RAID volume building process is up to “RAID Building” then the data volume is capable to be accessed. WARNING Creating RAID destroys all data in the current RAID volume. The data is unrecoverable. With a RAID 1, RAID 5, RAID 6, or RAID 10 volume, you can also add a spare disk after the RAID is created. See Chapter 6: Tips and Tricks > Adding a Spare Disk for details. For more information on RAID, see Appendix C: RAID Basics. RAID Level You can set the storage volume as JBOD, RAID 0, RAID 1, RAID 5, RAID 6 or RAID 10. RAID configuration is usually required only when you first set up the device. A brief description of each RAID setting follows: RAID Levels Level JBOD RAID 0 RAID 1 RAID 5 Description The storage volume is a single HDD with no RAID support. JBOD requires a minimum of 1 disk. Provides data striping but no redundancy. Improves performance but not data safety. RAID 0 requires a minimum of 2 disks. Offers disk mirroring. Provides twice the read rate of single disks, but same write rate. RAID 1 requires a minimum of 2 disks. Data striping and stripe error correction information provided. 53 RAID 6 RAID 10 WARNING RAID 5 requires a minimum of 3 disks. RAID 5 can sustain one failed disk. Two independent parity computations must be used in order to provide protection against double disk failure. Two different algorithms are employed to achieve this purpose. RAID 6 requires a minimum of 4 disks. RAID 6 can sustain two failed disks. RAID 10 has high reliability and high performance. RAID 10 is implemented as a striped array whose segments are RAID 1 arrays. It has the fault tolerance of RAID 1 and the performance of RAID 0. RAID 10 requires 4 disks. RAID 10 can sustain two failed disks. If the administrator improperly removes a hard disk that should not be removed when RAID status is degraded, all data will be lost.

Backup There are a number of ways to back up data with the N7700SAS. Nsync You can backup a share folder to another N7700SAS (Nsync Target) or any FTP server for safe keeping as long as you have appropriate access right on that target. When using Nsync between two N7700SASs, you have the option to transmit files securely between two N7700SASs. If the files on your N7700SAS are lost for any reason, you can restore those files from the target N7700SAS. To backup files regularly, you can set up a scheduled task to run only once, daily, weekly, or monthly. You can also limit the bandwidth of your Nsync tasks, so other users on the network can share the bandwidth equally. Under the Backup menu, click Nsync and the Nsync window appears. Below is a description of each field: Nsync Item Add Edit Restore Del Task name Server Share folder Last Time Last Status Schedule Action Bandwidth Setting Description Click to add a Nsync task Click to Edit an Nsync task. Restore share folder from an Nsync target. Click to delete an Nsync task. Backup files on Nsync target is also deleted. The name of your Nsync task. The IP address of your target server The share folder you would want to backup. The time when the last Nsync task was executed. The status of your last Nsync task. Schedule backup of your share folders. Administrator can run or stop an Nsync task by pressing the action button. Bandwidth control on Nsync tasks. Add Nsync Task From the Nsync screen, click Add to display the Add Nsync Task screen. 94 Add Nsync Task Item Description Task Name The name of your Nsync task.

Target Server IP The IP address of your target server. Address Source Folder The share folder you want to backup. Authorized Username The account name on the target server. on Target Server 95 Password on Target Server Test Connection Schedule Time Type Add NOTE The password for the username on the target server. Click to check the connection to the Target Server. Enable or Disable schedule backup of your share folders. The time when the Nsync task will run. Select whether to run the Nsync task daily, weekly, or monthly. Daily: input the time of day to execute Nsync task. Weekly: input which day of the week to execute the task. Monthly: decide which day of the month to execute the task. Press Add to submit your settings. Before starting an Nsync Task, make sure the target server’s Nsync Server (or FTP Server) is enabled. Setting Up an Nsync Target on an Nsync Device On the Nsync target server, the administrator of that server has to set up a user account with a folder named “nsync” and grant write access. 1. On the Nsync server, add a user for Nsync source (ex. nsyncsource1). For instructions on how to add a user on the N7700SAS, see Chapter 4: User and Groups Authentication> Local User Configuration > Add Users. 2. On the Nsync server, grant that user (ex. nsyncsource1) write access to the nsync folder. For instructions on how to set up a folder’s ACL, see Chapter 4: Storage management> Shore Folder> Folder Access Control List (ACL). 3. Once this is done, the target server will start accepting Nsync tasks from server using that ID and password. Setting Up an Nsync Target on Another Device If you selected “Other Device” when setting up your Nsync task, the N7700SAS will use the FTP protocol to back up the share folder. On the external storage device, make sure there is a folder named “nsync”, and the Auth ID has writable permission in that folder. Designating N7700SAS as an Nsync Target The N7700SAS can act as an Nsync server, enabling another Nsync-equipped Thecus NAS at a remote location backup their files to this N7700SAS. From the System Network menu, choose the Nsync Target item, and the Nsync Target Server screen appears.

Once a USB hard disk has successfully mounted, the entire volume will be linked automatically to the default USB HDD folder. The N7700SAS supports up to 4 USB external storage devices. All file names on the USB disk volume are case sensitive. The N7700SAS also supports eSATA hard disks with its eSATA port. Before attaching an eSATA or USB disk drive to N7700SAS, you have to partition and format it on a desktop computer or a notebook first. The attached device will be located at \\192.168.1.100\usbhdd\sdf1 where 192.168.1.100 means the IP address of N7700SAS and sdf1 stands for the first partition on disk #6, the eSATA or USB disk drive. If it is an NTFS partition, NAS users can open or copy files from \\192.168.1.100\usbhdd\sdf1 but cannot add new files or modify existing files. NOTE If you want to write to an USB storage device, the file system must be FAT32. USB FAT32 Storage Partition NTFS Partition Read OK OK Write OK - Adding a Spare Disk With a RAID 1, RAID 5, RAID 6, or RAID 10 volume, you can add a spare disk after the initial RAID is setup. To add a spare disk, follow the steps below: 1. On the RAID Configuration Screen, tick the checkbox of the hard disk you wish to designate as a spare disk. 2. Click Add Spare. The disk will be configured as a spare disk. The system automatically rebuilds the spare disk when one of the disks in the RAID set fails. Remote Administration You can set up your N7700SAS for remote administration. With remote administration, you can access your N7700SAS over the Internet, even if your N7700SAS is behind a router. This is especially useful if you are traveling and suddenly need a file from your N7700SAS. Setting up remote administration is a three-part process, and will require the following equipment: • • • • Thecus N7700SAS NAS device Cable / DSL Router with Dynamic DNS support Home PC Internet Connection NOTE Router setup will differ slightly depending on router used. For this example, we will use the Asus WL500g because it has support for Dynamic DNS. Contact your router hardware vendor for setup help. 115 Part I - Setup a DynDNS Account 1.

Hard Drive Damage When a hard drive is damaged and data in the RAID volume, the system LCD will display warning message also the system beeps. Replacing a Hard Drive To replace a hard disk drive in the N7700SAS: 1. Remove the tray with the damaged hard disk. 2. Unscrew the damaged hard disk and remove it from the tray. 3. Slide a new hard disk into the tray and fasten the screws. 4. Insert the hard disk tray back into the N7700SAS until it snaps into place. You can also lock it with a key if desired. 5. The LED blinks green when the HDD is accessed. RAID Auto-Rebuild When using RAID 1, 5, 6, or 10 on the N7700SAS, you can use the auto-rebuild function when an error is detected. 1. When a hard disk fails the system beeps and/or an email notification is sent to specified receivers. 2. Check the LCD to see which disk has failed. 3. Follow the steps mentioned above to replace the failed hard disk. 4. The system automatically recognizes the new hard disk and starts the auto-rebuild sequence to resume its status before the hard disk crash. 117 Chapter 7: Troubleshooting Forgot My Network IP Address If you forget your network IP address and have no physical access to the system, you can find out the IP address by either looking directly onto the N7700SAS’s LCD panel, or by using the setup wizard to retrieve the IP of your N7700SAS. 1. Start the Setup Wizard, and it will automatically detect all Thecus IP storage products on your network. 2. You should be able to find the IP address of the N7700SAS which you have forgotten in the Device Discovery screen. Can't Map a Network Drive in Windows XP You may have problems mapping a network drive under the following conditions: 1. The network folder is currently mapped using a different user name and password. To connect using a different user name and password, first disconnect any existing mappings to this network share. 2. The mapped network drive could not be created because the following error has occurred: Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again. To check out existing network connections, type net use under the DOS prompt. You may refer the URL below for more network mapping information. http://esupport.thecus.com/support/index.php?_m=downloads&_a=viewdownload& downloaditemid=57&nav=0 Restoring Factory Defaults From the System menu, choose the Factory Default item and the Reset to Factory Default screen appears. Press Apply to reset the N7700SAS to factory default settings. WARNING Resetting to factory defaults will not erase the data stored in the hard Problems with Time and Date Settings The administrator is able to select an NTP Server to keep the N7700SAS’s time synchronized. However, if the N7700SAS can not access the Internet, you may encounter a problem when setting the Time and Time Zone. If this happens: 1. Login to the Web Administration Interface. 2. Navigate to System Management>Time. 3. Under NTP Server, select No. 118 4. Set the Date, Time, and Time Zone. 5. Click Apply. In addition, if the N7700SAS is able to access the Internet and you want to keep the NTP Server clock.isc.org by default, please make sure the DNS Server is correctly entered, thereby allowing the NTP Server name to correctly resolve. (See System Network > WAN > DNS Server) Dual DOM Supports for Dual Protection The most advance and useful of N7700SAS is Dual DOM implemented. In the normal circumstance, it has no need to have this feature involved. But with irresistible cause like power cut or human error by accident occurred especially during system booting stage, this will become the great feature to prevent system down time. Practically while it happened, system will try to recovery the DOM 1 from DOM 2 first. If it is unachievable then system can boot from DOM 2. And all of this procedure can be operated by LCM. NOTE The Dual DOM in DOM1 is default master and FW upgrading will only execute in DOM1 unlike DOM2 is ‘Read only” initially. Any circumstance occurred, while DOM2 successes recover DOM1. The FW will be version of DOM2. Therefore, it may need to upgrade to the version of DOM1 it has. If DOM1 can not be recovery from DOM2, then system will boot up from DOM2. The original configuration in DOM1 may need to setup again with DOM2 operation. 119 Chapter 8: Revision updated (FW 3.00.03 to 3.00.04) What’s New There are additional features implemented into the new 3.00.04 version firmware. RAID Expansion for iSCSI Target Volume First, the iSCSI volume is now able to expand its capacity from unused space. From the volume list, simply select the iSCSI volume you like to expand and click the Expand button: You will then see the dialog box displayed below. Drag the Expand Capacity bar to the size you want. Then press Expand to confirm the operation. 120 RAID Volume Encryption With firmware v3.00.04, you can protect your data by using RAID Volume Encryption function to prevent the risk of data exposure. To activate this function, the Encryption option needs to be enabled while the RAID is created and followed by password input for identification. Also, an external writable USB disk plugged into any USB port on the system is required to save the password you have entered while the RAID volume is being created. See the screenshot below for details. Once the Create button has been pressed with the Encryption checkbox enabled, the following message pop-up will appear for confirmation. After the RAID volume has been created, you may remove this USB disk until the next time the system boots. The RAID volume can not be mounted if the USB disk with key can not be found in any system USB port when the volume is accessed. To activate the encrypted volume, plug the USB disk containing the encryption key and into any system USB port. We are strongly recommended copying the RAID volume encryption key to a safe place. You can find the encryption key file from the USB disk in the following format: (RAID volume created date)_xxxxxx.key WARNING Please keep USB disk in a safe place and also backup the encrypted key. There is no way to rescue data back if the key is lost. 121 NOTE 1. With RAID volume encryption enabled, the system performance will goes down. 2. With RAID volume encryption enabled, RAID volume expansion will operated in off line mode. RAID volumes with encryption enabled will be displayed with a key lock symbol next to volume ID name. iSCSI Thin-Provisioning An advanced thin-provisioning for iSCSI feature is available in this firmware release. With this function, the iSCSI capacity can be more flexible and more efficiently serve more users. The idea for iSCSI thin-provisioning is sharing the available physical capacity to a number of iSCSI target volumes and also setup virtual capacity to expand the physical size while it needed. To setup iSCSI thin-provisioning, go to Space Allocation under the Storage category. The iSCSI thin-provisioning volume needs to be created first. Simply click iSCSI Thin-Provision Target. You can refer the screen shot below. 122 Next, setup the physical capacity for iSCSI thin-provision volume by dragging the Allocation bar to the desired size. After the size has been determined, click OK to confirm. Now you will see the iSCSI thin-provisioning volume is available from the list. Please refer to the screenshot below. 123 Now you can start to create iSCSI targets to join the newly-created iSCSI thin-provision volume. Basically, the iSCSI target under iSCSI thin-provisioning has exactly same settings screen as the standard iSCSI target volume creation. The only difference is the “Virtual Size” of capacity. Unlike creating standard iSCSI target volumes, the capacity has been physically allocated. The iSCSI target volume creation under thin-provisioning can virtually be up to 16000GB (16TB). Let’s take the example below: 1. The physical size for the iSCSI thin-provision volume is 333.88GB. You can refer the screenshot above. 2. The iSCSI target volume under thin-provisioning starts with 333.38GB in physical size and you may use drag the Virtual Size bar to select the desired virtual size. The maximum virtual size is 16000GB. 3. In this case, if you make the iSCSI target volume 1700GB, then the virtual size is available for the next iSCSI target volume under thin-provisioning is 14300GB (16000-1700). 4. The limit is 5 iSCSI target volumes under thin-provisioning or a virtual size of 16000GB. iSCSI Thin-provision physical size starts with 333.8GB The virtual capacity is limited to 16000GB 124 The screen shot for iSCSI target volume creation under thin-provisioning; the physical capacity 333.8GB. The screen shot to setup an iSCSI target volume under thin-provisioning of 1700GB. iSCSI target volume creation. The maximum virtual size is 14300GB (16000GB – 1700GB(1st iSCSI target volume)). 125 This screenshot lists iSCSI target volumes created under thin-provisioning. The 2nd iSCSI target volume under thin-provisioning has been created with a capacity of 14300GB. This message appears if there is no more room for new iSCSI target creation. NOTE 1. Each RAID volume can only create one iSCSI thin-provision volume. 2. Each thin-provision volume can only create 5 iSCSI target volumes. 3. The notification will send out while the physical size of iSCSI thin-provision capacity has used up to 90%. iSCSI LUN ID When iSCSI target volume has been created, there is a default LUN ID of 0 in previous firmware versions which was un-configurable. From v3.00.04, it is configurable from 1 to 254 with a default of the next available number in ascending numerical order. The LUN ID is unique and can not be duplicated except for LUN ID 0. 126 Error Corrections None 127 Chapter 9: Revision updated up to FW 3.00.08 What’s New There are additional features implemented into the new 3.00.08 version firmware. Updated Login User Interface There is a brand new design for the admin login UI. NOTE The previous chapters have screenshots of the original user interface. Please note that all changes are visual only. There are no functional changes. Updated Photo Server User Interface Same as the admin login user interface, the photo server has a brand new art design from its previous version. 128 Disclaimer Page Added The following disclaimer page has been added to this firmware release. Please click the check box if you do not want to have this page displayed during the next login. 129 Updated Main User Interface The look and icons of the main user interface have been updated. Add On-Line Register Service From main menu tree, there is a new “On-line Register” option added with this firmware release. This on-line register service can periodically update the user when new firmware and software modules are released by Thecus. To enable this service, simply check the “Enable” check box. By enabling this service, the items in bold will be sent to Thecus via the Internet. Other than the defined items sent upon registration, there are also two additional items: “HDD Info” and “Time Zone”. These two optional items can also be sent to Thecus anonymously for analysis and statistics purposes. To send these items, simply check the desired checkboxes to help Thecus improve its products and services. 130 Added Rsync Setting under Nsync Target The Thecus Nsync feature has added a third way to use Rsync to replicate data between two systems. For the target side to allow source cross data, the Rsync target server needs to first select “Enable” and then assign a username and password for authentication. NOTE The Rsync target server username and password is used for this replication feature only. It is not related to the standard local user. Added Rsync Backup Feature Thecus Nsync now provides backup features to other Thecus NAS with VPN protection or legacy FTP server with the added Rsync option. Using “Rsync” to backup data to other Thecus NAS devices uses the exact same procedure as the original Nsync method. The only thing that needs to be done is to 131 enable the sync target server and input a valid username and password to grant access permission. Added 2nd Gateway for Clients of DHCP Server Route The adding of a 2nd gateway has been phased in to serve clients that use their Thecus NAS as a DHCP server to have another route to balance traffic bandwidth. NOTE If the IP sharing mode setting is set to “Enable” under WAN port, then this 2nd gateway cannot be configured. 132 Added Dual DOM for Auto Repair The unique Dual DOM feature can now perform “Auto Repair”. The Thecus NAS will backup up to five versions of the system configuration either by the default timing of 1:00am every day automatically or as scheduled by the user. This unique “Auto Repair” will be triggered if the primary DOM has a booting issue. In this instance, the 2nd DOM will take over the boot function. Then, the system will automatically load the most recent system configuration backup image to repair the primary DOM. 133 Chapter 10: Version 3.01.00 Firmware Updates What’s New There are additional features implemented into the new 3.01.00 version firmware. Updated Login User Interface The design of the admin login UI has been completely updated. NOTE The previous chapters have screenshots of the original user interface. Please note that all changes are visual only. There are no functional changes. Updated Main User Interface The look and icons of the main user interface have been updated. Additionally, a “My Favorite” shortcut has been added to allow the user to designate often used items and have them display on the main screen area. The figure below displays 12 default favorite functions. 134 Administrators can add or remove favorite functions to My Favorites by right clicking the mouse on the menu tree. The other way administrators can add favorite functions is by clicking the “Add Favorite” icon in each function screen. Please refer figure below in red circuit icon. To return to the favorite screen, simply click “My Favorite” located at the left hand corner of the main screen. 135 Added Additional Mode Support for Link Aggregation Link Aggregation now has six supported modes. The administrator can choose the most suitable mode to fit the network environment. You may choose from the following options: z z z z z z z Disable Load Balance Failover Balance-XOR 802.3ad Balance-TLB Balance-ALB See the right diagram for details. Additional LAN Card support (N7700PRO and N7700+ Only) With the system reserved PCI-e slot, you can install a supported third-party LAN card for a 3rd or 4th LAN port (the maximum supported ports is 2). Below is a list of currently supported LAN cards: z z z z Intel Ethernet Server Adaptor X-520 DA2 10G NIC Intel Ethernet Server Adaptor X-520 SR1/SR2 10G NIC Intel Gigabit EF Dual Port Server Adaptor 82576GB 1G NIC Tehuti ENW-9800 10G NIC After you have installed a supported NIC into the system, you will see the setting item appear under “System Network” named “Additional LAN1” and “Additional LAN2” accordingly. The default IP addresses will be “192.168.4.254” and “192.168.5.254”. Below as an example with an Intel 2-port 10G NIC has installed into the system. Note that the link detection and speed information is displayed. Error Corrections The description of the schedule settings for the snapshot has changed as below to avoid confusion. Original: The snapshot schedule rules can be setup for monthly, weekly or daily hour. Clicking on Apply after firmed with desired schedule Amendment: The snapshot schedule rules can be setup for monthly, weekly or daily hour.

A RAID system accesses several hard disks simultaneously, which improves I/O performance over a single hard disk. Data security is enhanced by a RAID, since data loss due to a hard disk failure is minimized by regenerating redundant data from the other RAID hard disks. Benefits RAID improves I/O performance, and increases data security through fault tolerance and redundant data storage. Improved Performance RAID provides access to several hard disk drives simultaneously, which greatly increases I/O performance. Data Security Hard disk drive failure unfortunately is a common occurrence. A RAID helps prevent against the loss of data due to hard disk failure. A RAID offers additional hard disk drives that can avert data loss from a hard disk drive failure. If a hard drive fails, the RAID volume can regenerate data from the data and parity stored on its other hard disk drives. RAID Levels The Thecus N7700SAS supports standard RAID levels 0, 1, 5, 6, 10, and JBOD. You choose a RAID level when you create a system volume. The factors for selecting a RAID level are: • • • Your requirements for performance Your need for data security Number of hard disk drives in the system, capacity of hard disk drives in the system The following is a description of each RAID level: RAID 0 RAID 0 is best suited for applications that need high bandwidth but do not require a high level of data security. The RAID 0 level provides the best performance of all the RAID levels, but it does not provide data redundancy. RAID 0 uses disk striping and breaking up data into blocks to write across all hard drives in the volume. The system can then use multiple hard drives for faster read and write. The stripe size parameter that was set when the RAID was created determines the size of each block. No parity calculations complicate the write operation. RAID 1 RAID 1 mirrors all data from one hard disk drive to a second one hard disk drive, thus providing complete data redundancy. However, the cost of data storage capacity is doubled. This is excellent for complete data security. 140 RAID 5 RAID 5 offers data security and it is best suited for networks that perform many small I/O transactions at the same time, as well as applications that require data security such as office automation and online customer service. Use it also for applications with high read requests but low write requests. RAID 5 includes disk striping at the byte level and parity information is written to several hard disk drives. If a hard disk fails the system uses parity stored on each of the other hard disks to recreate all missing information. RAID 6 RAID 6 is essentially an extension of RAID level 5 which allows for additional fault tolerance by using a second independent distributed parity scheme (dual parity) Data is striped on a block level across a set of drives, just like in RAID 5, and a second set of parity is calculated and written across all the drives; RAID 6 provides for an extremely high data fault tolerance and can sustain two simultaneous drive failures. This is a perfect solution for mission critical applications. RAID 10 RAID 10 is implemented as a striped array whose segments are RAID 1 arrays. RAID 10 has the same fault tolerance as RAID level 1. RAID 10 has the same overhead for fault-tolerance as mirroring alone. High I/O rates are achieved by striping RAID 1 segments. Under certain circumstances, RAID 10 array can sustain up to 2 simultaneous drive failures Excellent solution for applications that would have otherwise gone with RAID 1 but need an additional performance boost. JBOD Although a concatenation of disks (also called JBOD, or "Just a Bunch of Disks") is not one of the numbered RAID levels, it is a popular method for combining multiple physical disk drives into a single virtual one. As the name implies, disks are merely concatenated together, end to beginning, so they appear to be a single large disk. As the data on JBOD is not protected, one drive failure could result total data loss. Stripe Size The length of the data segments being written across multiple hard disks. Data is written in stripes across the multiple hard disks of a RAID. Since multiple disks are accessed at the same time, disk striping enhances performance. The stripes can vary in size. 141 Disk Usage When all 7 disks are of the same size, and used in RAID, N7700SAS disk usage percentage is listed below: RAID Level Percentage Used RAID 0 100% RAID 1 1/n x 100% RAID 5 (n-1)/n x 100% RAID 6 (n-2)/n x 100% RAID 10 50% JBOD 100% n：HDD number 142 Appendix D: Active Directory Basics Overview With Windows 2000, Microsoft introduced Active Directory (ADS), which is a large database/information store. Prior to Active Directory the Windows OS could not store additional information in its domain database. Active Directory also solved the problem of locating resources; which previously relied on Network Neighborhood, and was slow. Managing users and groups were among other issues Active Directory solved. What is Active Directory? Active Directory was built as a scalable, extensible directory service that was designed to meet corporate needs. A repository for storing user information, accounts, passwords, printers, computers, network information and other data, Microsoft calls Active Directory a "namespace" where names can be resolved. ADS Benefits ADS lets the N7700SAS integrate itself with the existing ADS in an office environment. This means the N7700SAS is able to recognize your office users and passwords on the ADS server. Other major benefits ADS support provides include: 1. Easy integration of the N7700SAS into the existing office IT infrastructure The N7700SAS acts as a member of the ADS. This feature significantly lowers the overhead of the system administrator. For example, corporate security policies and user privileges on an ADS server can be enforced automatically on the N7700SAS. 2. Centralized user/password database The N7700SAS does not maintain its own copy of the user/password database. This avoids data inconsistency between the N7700SAS and other servers. For example, without ADS support, an administrator might need to remove a specific user privilege on the N7700SAS and each individual server. With ADS support, the change on an ADS server is known to all of its ADS members. 143 Appendix E: Licensing Information Overview This product included copyrighted third-party software licensed under the terms of GNU General Public License.

Permission is granted to use CGIC in any application, commercial or noncommercial, at no cost. HOWEVER, this copyright paragraph must appear on a "credits" page accessible in the public online and offline documentation of the program.

GNU General Public License Version 2, June 1991 Copyright © 1989, 1991 Free Software Foundation, Inc. 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. PREAMBLE The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what 145 they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under 146 these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 147 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 148 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS 149
