Quantum DXi3500 and DXi5500 User’s Guide xx Chapter 1 1DXi3500 and DXi5500 System Description
This chapter describes the DXi3500 and DXi5500 system and its components. The chapter consists of: • Overview • Features and Benefits • DXi3500 and DXi5500 Systems • Hard Drive Storage • Supported RAID Configurations • Typical Configurations
Overview
The DXi3500 and DXi5500 Enhanced Backup Solution utilizes a disk- based backup system to complement a tape library. This solution addresses the most important problems facing Information Technology professionals: • Time Required for Backup • Confidence in Completing the Backup • Time to Restore Data
Quantum DXi3500 and DXi5500 User’s Guide 1 Chapter 1 DXi3500 and DXi5500 System Description Features and Benefits
Time Required for Not only is the amount of data that needs to be backed up growing, but Backup 1 the time window for performing the backup is shrinking due to the impact of global operational expansion. Adding more tape drives is no longer an efficient way to reduce the time required for backup.
Confidence in Confidence in completing the backup job within the backup window can Completing the Backup 1 be very low because of time constraints or “hang ups” during the backup process due to errors generated by mechanical problems. If these types of errors could be eliminated by removing issues that are inherent in any mechanical device, confidence in the backup job completing would improve greatly.
Time to Restore Data 1 The time required to restore data from a tape library is determined by how long it takes to mount a cartridge in a tape drive and find the proper position on the tape. This can take several minutes and then the restore time is also reduced by the tape drive transfer speed. Restoring data from hard drives (emulating tape cartridges) improves restore time by eliminating the time required to load a cartridge and transfer speed restrictions.
Features and Benefits
Both the DXi3500 and DXi5500 systems provides the following features and benefits: • High availability features: •RAID 5 file system • Event monitoring and logging • Redundant cooling, power supplies, and disk parity protection • Global spare (DXi5500 Only) and hot-swappable hard drives • Flexible alert notification including e-mail and SNMP traps • Serial ATA II drive technology

Quantum DXi3500 and DXi5500 User’s Guide 3 Chapter 1 DXi3500 and DXi5500 System Description Data Reduction
Data Reduction
Data reduction is the process of reducing the amount of storage capacity required to store your data. The DXi3500 and DXi5500 systems provide two techniques to optimize the storage space required on your system: • Data De-duplication • Hardware Compression
Data De-duplication 1 The DXi3500 and DXi5500 systems can reduce the amount of storage capacity required through a data de-duplication process. The term data de-duplication refers to the elimination of redundant data. During this process, duplicate data is ignored, leaving only one copy of the data to be stored. Indexing data is retained and used to restore the previously de- duplicated data. Since only the unique data is stored on the system, the amount of required storage space is reduced. For more information on data de-duplication ennoblement, refer to NAS Area on page 40 and Adding a Partition on page 54.
Caution: Server side software compression, encryption, or multiplexing should NOT be used with the DXi3500/ DXi5500 system. This can impair the systems ability to de- duplicate data.
Hardware Compression 1 The DXi3500 and DXi5500 systems are configured with the Optyon™ hardware-based compression card. With an Optyon card installed in your system, unique data that has been through the de-duplication process can be compressed at a ratio of 2:1. This enables you to maximize the storage capacity of your system as well as increase overall backup performance.

Caution: Removing hard drives during system operation may cause loss of data or degraded system performance. Contact Quantum customer support (see Contacts on page xvi) to report any hard drive failure.
The hard storage area can be used in the following ways: • Virtual Tape Storage • Network Attached Storage (NAS)
Virtual Tape Storage 1 Virtual tape storage or virtual tape library (VTL) allows the storage space on these hard drives to appear to the backup application as tape cartridges (DLT or LTO). Data is stored on the hard drives through an interface that appears as a DXi series system. This allows backup applications to recognize and integrate a DXi series system into a data center environment just like a physical tape library.
Network Attached The DXi3500 and DXi5500 systems have the ability to serve as a NAS Storage (NAS) 1 appliance for backup purposes (see figure 6). The following backup protocols are supported:
Quantum DXi3500 and DXi5500 User’s Guide 11 Chapter 1 DXi3500 and DXi5500 System Description Hard Drive Storage
• CIFS Protocol • NFS Protocol
CIFS Protocol 1
The CIFS (Common Internet File System) protocol defines a standard for remote file access using many computers at a time. This protocol allows users with different platforms to share files without installing additional software. This protocol is used with Windows networks.
NFS Protocol 1
The NFS (Network File System) protocol was originally designed by Sun™ Microsystems and allows all network users to access shared files stored on computers of different types. NFS provides access to shared files through an interface called the Virtual File System (VFS) that runs on top of TCP/IP. Users can manipulate shared files as if they were stored locally on the user's own hard disk. With NFS, computers connected to a network operate as clients while accessing remote files, and as servers while providing remote users access to local shared files. This protocol is used with UNIX/Linux networks.

The NAS portion of DXi3500/DXi5500 is optimized for backup rather than file sharing.
Quantum DXi3500 and DXi5500 User’s Guide 12 Chapter 1 DXi3500 and DXi5500 System Description Hard Drive Storage
RAID Sets 1 The DXi3500/DXi5500 system is divided into RAID sets. The number of RAID sets differs depending on the system: • DXi3500 can contain two RAID sets: • The first RAID set is made up of either the first four drive sleds (drive sleds 1-4) in a four drive system or eight drive sleds (drive sleds 1-8) in an eight drive system. • If the original system was upgraded from four to eight drives, the second RAID set is made up of the last four drive sleds (drive sleds 5-8). • DXi5500 can contain four RAID sets: • The first RAID set is made up of the first six drive sleds (drive sleds 1-6). • The second RAID set is made up of the next five drive sleds (drive sleds 7-11 with drive 12 as a hot spare). If the DXi5500 is fully populated with twenty-four hard drives: • The third RAID set is made up of the next six drive sleds (drive sleds 13-18 if installed). • The fourth RAID set is made up of the next five drive sleds (drive sleds 19-23 with drive 24 as a hot spare).
Hard Drive Failures 1
• In a DXi3500, each RAID set can sustain a single hard drive failure. • In a fully populated DXi5500, there are two hot spares. The first hot spare protects the first and second RAID sets and the second hot spare protects the third and fourth RAID sets. If a hard drive failure occurs, one of the two designated hot spares is used to rebuild the RAID set. Once the RAID set is rebuild, the DXi5500 can sustain another single hard drive failure.
Virtual Tape Cartridges 1
The DXi3500 can contain 1600 virtual cartridges and the DXi5500 can contain 3200 virtual cartridges.
Quantum DXi3500 and DXi5500 User’s Guide 13 Chapter 1 DXi3500 and DXi5500 System Description Supported RAID Configurations
Supported RAID Configurations
RAID is short for Redundant Array of Independent (or Inexpensive) Disks, which is a category of hard disk drives that employ two or more drives in combination for fault tolerance and performance. There are a number of RAID levels in use today such as 0, 1, 3, 5, and 10. The DXi3500 and DXi5500 systems support RAID 5, but only the DXi5500 systems can be configured with a hot spare.
RAID 5 Configuration 1 The RAID 5 configuration is the most common RAID level in use today. RAID 5 minimizes the write bottlenecks of other RAID levels by distributing parity stripes over a series of hard drives. In doing so it provides relief to the concentration of write activity on a single drive, which in turn enhances overall system performance. Instead of allowing any one drive in the array to assume the risk of a bottleneck, all of the drives in the array assume write activity responsibilities. The distribution frees up the concentration on a single drive, improving overall subsystem throughput.
Typical Configurations
The DXi3500/DXi5500 system has many advantages over typical tape cartridge based systems such as faster data transfer, instant availability, and greater reliability. There are several ways to implement a backup strategy using a DXi3500 and DXi5500 system. Refer to the following examples: • Disk to Disk to Tape Scenario • Disk to Disk Replication Scenario
Quantum DXi3500 and DXi5500 User’s Guide 14 Chapter 1 DXi3500 and DXi5500 System Description Typical Configurations
Disk to Disk to Tape In a Disk to Disk to Tape scenario (see figure 7), backup data is written Scenario 1 from the backup server(s) directly to the DXi3500/DXi5500 via a network or SAN (Step: 1). Once the backup data is stored on the DXi3500/ DXi5500, you can replicate the data to a tape library (Step: 2) using a backup ISV (Independent Software Vendor). This is a simple and effective way of taking advantage of the faster transfer speed and reliability of the DXi3500/DXi5500.
Figure 7 Disk to Disk to Tape Scenario
Disk to Disk Replication In a Disk to Disk Replication scenario (see figure 8), backup data is written Scenario 1 from smaller, remote locations and stored at a larger or centralized data center via a network. Backup servers at the remote sites would backup
Quantum DXi3500 and DXi5500 User’s Guide 15 Chapter 1 DXi3500 and DXi5500 System Description Typical Configurations
their data to a local DXi system. The DXi system would then replicate that backup data to a DXi system located in a larger data center. If the data is lost at a remote site, the backup data could be rebuilt from the replicated data located on the larger data center’s DXi system.

Data Replication
Data replication is the process of creating and managing duplicate versions of your data. The replication process not only copies the data but also allows you to schedule the replication process so it can run automatically. For optimization purposes, the underlying data is continuously updated and will become available when the replication is either run manually or via a scheduled replication. When replication is configured on the DXi3500 or DXi5500, copies of a VTL partition or NAS share can be copied to a remote DXi system (see Data Replication on page 107).
Note: Data replication is a licensed feature for the DXi3500 and DXi5500. Contact your Quantum Sales representative for more information on purchasing this option.
• Data Recovery • Data Failback
Note: For more information on setting up your systems for data replication, see chapter 5, Implementing a Data Replication Plan
Quantum DXi3500 and DXi5500 User’s Guide 25 Chapter 2 Basic Operations Data Replication
Data Recovery 2 The data recovery process allows a replicated VTL partition or NAS share on a secondary or “target” DXi system to become available for recovery purposes. For more information on recovering a replicated VTL partition or NAS share, see Data Replication on page 107.
Data Failback 2 Data failback allows a replicated VTL partition or NAS share to be replicated from the secondary or “target” system back to the original source system or other DXi system. Once the VTL partition or NAS share is replicated back to the original source system, the VTL partition can be recovered and the system returned to normal operation. For more information on failback, see Data Replication on page 107.

See Joining a Domain using a Domain User Credential for an example. • Administrator Password - Enter the Administrator Password.
Quantum DXi3500 and DXi5500 User’s Guide 44 Chapter 3 DXi3500 and DXi5500 Remote Management Configuration
• Confirm Administrator Password - Re-enter the password to confirm. 2 Click Apply.
Note: When the system is joined to the Active Directory domain all the share security is managed by the MMC (Microsoft Management Console) that is running on the domain controller. By default, when a CIFS share is created the default security setting is to allow access for all users. Any access restriction on individual users will have to be managed from the MMC.
Joining a Domain using a Domain User Credential 3
Many large companies do not want to use the Administrator account to join the ADS domain. They prefer to delegate a normal domain user account with special rights to join the domain. The purpose of this section is to provide an example of delegating a normal domain user account with special rights to join the domain. To facilitate this example, the following information is assumed: • The ADS is running on a Windows 2003 Server system • ADS domain name: abc.def.xyz.com • "user1" is a normal domain user that has basically no administrative privileges • The server host name is DX1. • DNS domain name: abc.def.xyz.com • DNS IP address: 10.20.30.40 1 Steps to complete on the Windows 2003 MMC: a Delegate the right to join the domain • Select the domain name abc.def.xyz.com • Right click and choose: "Delegate Control" | Next | Add • Type the username: user1 •OK | Next • Delegate the following common tasks • Join a computer to the domain
Quantum DXi3500 and DXi5500 User’s Guide 45 Chapter 3 DXi3500 and DXi5500 Remote Management Configuration
•Next | Finish b Delegate the right to read/write dNSHostname and servicePrincipalName: • Select the organizational unit "Computers" or the appropriate name. This is the folder that contains individual computers that belong to the domain. • Right click and choose: "Delegate control" | Next | Add • Type the username: user1 • OK | Next | Create a custom task to delegate • Next | Only the following objects in the folder: • Check the box: Computer objects • Check the box: Create selected objects in this folder • Next | Check box: Property-specific • Scroll down the list and check the boxes for: •Read dNSHostName • Write dNSHostName • Read servicePrincipalName • Write servicePrincipalName •Next | Finish 2 Work to do on the GUI a Network page: Note on these edit boxes: •Hostname: DX1 • Domain name: Enter abc.def.xyz.com. This is the DNS domain name. The DNS domain name is usually, but not necessarily, identical with the ADS domain name. • Domain name server IP address: Enter 10.20.30.40. This is the IP address of the domain name server that can resolve the domain name abc.def.xyz.com that you are trying to join to.
Quantum DXi3500 and DXi5500 User’s Guide 46 Chapter 3 DXi3500 and DXi5500 Remote Management Configuration
b Windows Domain page: • Domain type: Active Directory • Domain name: abc.def.xyz.com
Note: You must use a fully qualified domain name; character case is not important.
• Primary Domain Controller: Preferred option if DNS is working: Use DNS discovery If DNS is not working well or if you cannot ping abc.def.xyz.com, then use the IP address of the PDC explicitly. If you cannot ping the domain name abc.def.xyz.com, you may not join successfully unless you can resolve abc.def.xyz.com using the command: # host abc.def.xyz.com ip_address where the ip_address is the IP address of DNS as specified at the bottom of the network page. • Organizational Unit: This is optional. There is usually a default organizational unit such as "Computers". If you want to join to an organizational unit that is different from the default, then enter the name of that organizational unit as seen in MMC. • Administrator Name: user1 • Password:
Troubleshooting ADS Join Issues 3
For troubleshooting purposes we will assume the sample settings in Joining a Domain using a Domain User Credential were used to join the domain abc.def.xyz.com through the remote management pages, but the operation failed. This assumption is important in that all the necessary settings were already written in relevant files and you can log on the server to perform a number of tests to determine the root cause.
Quantum DXi3500 and DXi5500 User’s Guide 47 Chapter 3 DXi3500 and DXi5500 Remote Management Configuration
1 Is the DNS server specified on the Network page capable of resolving the domain name? # nslookup abc.def.xyz.com Or # host abc.def.xyz.com 10.20.30.40 to see if the DNS server 10.20.30.40 can resolve abc.def.xyz.com. If it cannot, change to a different DNS server IP address on the Network page. 2 Specify the fully qualified domain name on the Windows Domain page. Do not specify the short name abc. Must specify abc.def.xyz.com. 3 Check the Primary Domain Controller. To avoid any DNS issue, enter the IP address of the PDC on the Windows Domain page. Make sure you can ping the PDC successfully. 4 Check the clock time difference Time on the ADS server: # net time -S abc.def.xyz.com Time on the local server: # date Make sure the time difference is less than 300 sec. 5 Make sure the username exists in the ADS. Test by logging in the Kerberos server: # kinit [email protected] Note that the name after '@' must be all capitalized. If the command fails, it should tell what happened. Again, must make sure ABC.DEF.XYZ.COM can be resolved by the DNS. If the command succeeds, you should run the next two commands: # klist This command is to list all the Kerberos tickets just issued to user1. # kdestroy This command is to destroy all the Kerberos tickets issued to user1.
Quantum DXi3500 and DXi5500 User’s Guide 48 Chapter 3 DXi3500 and DXi5500 Remote Management Configuration
6 If the username is not a member of the Administrator or Domain Admins group, then check to make sure he has the correct rights to join a domain: # net ads status -U [email protected] Make sure you see the following lines in the output: dNSHostName: dx1.abc.def.xyz.com servicePrincipalName: HOST/ dx1.abc.def.xyz.com servicePrincipalName: HOST/DX1 If these lines are absent, user1 does not have the required rights to join the domain. In this case, follow the instructions in Section C (both items 1.a and 1.b) to delegate enough rights to user1 so that he can join the domain. 7 Finally, the errors from joining ADS domain are logged in: /tmp/nas/cifs.ads.join The contents are overwritten each time you join the domain either from the GUI or by running an appropriate CLI command. The CLI command is not officially supported. You can run # nastool without options to show the syntax. Note that certain subcommands require a password. If you do not type the password option, you will be prompted interactively and the password entered will not be echoed on screen.

Configuring the Device Mappings 3
The Device Mapping page allows you to map or assign DXi3500/DXi5500 virtual devices (robot and tape drives) to specific iSCSI or Fibre Channel ports. The default setting for both the DXi3500 and DXi5500: • Ethernet port 1 is assigned the robot and tape drives 0 through 5. To access the Device Mapping page: 1 In the Hardware page, click Device Mapping. The management frame displays the Device Mapping page (see figure 39).
Quantum DXi3500 and DXi5500 User’s Guide 72 Chapter 3 DXi3500 and DXi5500 Remote Management Configuration
Figure 39 Device Mapping Page
2 There are four ways to assign virtual devices to a specific iSCSI or Fibre Channel port: •Click Auto Populate (Partition Per Port) to allow the DXi3500/ DXi5500 controller to automatically assign virtual devices to a port. The controller assigns a robot and partition to each port. Example: A system with 1 partition would have a robot assigned to LUN 0 and all other devices within that partition assigned to additional LUNs on that port. •Click Auto Populate (iSCSI only) to allow the DXi3500/DXi5500 controller to automatically assign virtual devices to ONLY the iSCSI ports. The controller assigns a robot and partition to each iSCSI port. Example: A DXi3500/DXi5500 has two potential iSCSI ports. A system with 2 partitions would have a robot assigned to LUN 0 on Eth 1 and Eth 2 and all other devices within that partition assigned to additional LUNs on that port.
Quantum DXi3500 and DXi5500 User’s Guide 73 Chapter 3 DXi3500 and DXi5500 Remote Management Configuration
•Click Auto Populate (FC only) to allow the DXi3500/DXi5500 controller to automatically assign virtual devices to ONLY the Fibre Channel ports. The controller assigns a robot and partition to each Fibre Channel port. Example: A DXi3500 has two potential Fibre Channel ports and a DXi5500 has four potential Fibre Channel ports. A system with 2 partitions would have a robot assigned to LUN 0 on FC 1 and FC 2 and all other devices within that partition assigned to additional LUNs on that port. •Click Add LUN to add additional rows or LUNs at the bottom of the page. The maximum number of LUNs is 256. • Use the drop down boxes located under the port number to select the devices mapped to that port. Do NOT assign the same device to more than one port unless your backup application can support multiple mappings of the same device to more than one port. Example: Assign the robot and tape drives 0 and 1 to Eth1. From the host, only the robot and tape drive 0 and 1 are visible from Eth1. Assign tape drive 2 and 3 to FC1. Only tape drive 2 and 3 are visible from FC1. •Click Clear to clear all of the device mappings. Please make note of the following device mapping restrictions: • The maximum number of virtual devices is 64 per system. • The maximum number of virtual tape drives on a Fibre Channel port is 32 per port. • The maximum number of virtual tape drives on an Ethernet port is 64. • The maximum number of virtual disks on an Ethernet port is 64. When all of the virtual devices have been assigned to the appropriate port, click Apply to accept the port settings.
Note: Microsoft Windows has a known issue recognizing more than eight LUNs on a single Fibre Channel port. See Microsoft Knowledge Base Article 310072: http://support.microsoft.com/default.aspx?scid=kb;en-us;310072 for information on reconfiguring Windows to overcome this limitation.

Configuring the iSCSI Options 3
The DXi3500/DXi5500 system allows you to control and configure each of the iSCSI Ethernet input ports that connect to the customer storage network. The iSCSI Ethernet input ports are numbered 0 through 1 and are located on the back of the DXi3500 and DXi5500 systems (see figure 40).

To access the iSCSI configuration page: 1 In the Hardware page, click iSCSI. The management frame displays the iSCSI Port Settings page (see figure 42).
Quantum DXi3500 and DXi5500 User’s Guide 75 Chapter 3 DXi3500 and DXi5500 Remote Management Configuration
Figure 41 iSCSI Configuration Page
Configure the following iSCSI settings as desired: • CRC/Checksum - Cyclic Redundancy Check is a common technique for detecting data transmission errors. Messages are divided into predetermined lengths that are divided by a fixed divisor. According to the calculation, the remainder number is appended onto and sent with the message. When the message is received, the computer recalculates the remainder and compares it to the transmitted remainder. If the numbers do not match, an error is detected. • Authentication for all iSCSI initiators - Authentication for iSCSI initiators is the process of identifying an initiator based on a username and password. If you want to authenticate the iSCSI initiators, enter a User Name and Password for the initiator. • Authentication for all iSCSI targets: • CHAP - Challenge Handshake Authentication Protocol is an authentication type in which the authentication agent (typically a network server) sends the client program a random value that is used only once and an ID value. Both the sender and peer share a predefined secret. The peer concatenates the random value (or nonce), the ID and the secret and calculates a one-way hash using MD5. The hash value is sent to the authenticator, which in turn builds that same string on its side, calculates the MD5 sum itself and compares the result with the value received from the peer. If
Quantum DXi3500 and DXi5500 User’s Guide 76 Chapter 3 DXi3500 and DXi5500 Remote Management Configuration
the values match, the peer is authenticated. If you want to authenticate the iSCSI targets with CHAP, select OK and enter a User Name and Password for the target. • SRP - Secure Remote Password is a password based authentication The two peers can be identified using a single password, or there can be combinations where the client is authenticated using SRP and the server using a certificate. The advantage of SRP authentication is that SRP does not require the server to hold the user's password. The SRP requires a verifier which is calculated using the user's password. If you want to authenticate the iSCSI targets with SRP, select OK and enter a User Name and Password for the target.
Configuring the Fibre Channel Options 3
The DXi3500/DXi5500 system allows you to control and configure each of the Fibre Channel input ports that connect to the customer SAN. To access the Fibre Channel page (see figure 42): 1 In the Hardware page, click Fibre Channel. The management frame displays the Fibre Channel Port Settings page (see figure 42).

Note: The DXi3500/DXi5500 system must be off-line to configure the Fibre Channel options.
2 While the Port WWNs are always unique, the Node WWNs can be set according to the Make the Node WWN section as follows: a Selecting Globally Unique but same for all ports makes the Node WWNs the same for all Fibre Channel ports. b Selecting Equal to the Port WWNs for each port makes the Node WWNs equal to the Port WWNs. 3 Selecting The Port Settings page (see table 18 for field descriptions) allows you to set the AL_PA, Loop ID and link speed for each Fibre Channel port connecting the DXi3500/DXi5500 system to the customer SAN.
Caution: If you are manually assigning the robot and tape drives to your Ethernet and Fibre Channel ports, you MUST assign the devices in numeric order starting with L0 and continuing with L1, L2, L3 and so forth. You MUST restart with L0 for each additional port. Do NOT assign the devices out of order.

Figure 58 Data Services Page
The Data Services page is divided into the following tabs: • Space Management • Data Replication
Space Management 3 When data de-duplication is enabled on the DXi3500 or DXi5500 system, it is not possible to accurately predict the amount of storage space required since the de-duplication process depends on the type of data being stored. This makes it necessary to define storage space thresholds so the user can be notified when storage space begins to run low. Space management provides the ability to monitor the storage space available on the system and notify the user if storage space begins to run low.
Note: When a “low-disk space” emergency occurs on a host, the current host will pause its replication activity and any source hosts that are currently replicating to this host are paused. When the “low-disk space” emergency ends, the current host will resume its replication activity and the source hosts that were replicating to this host resume.
Quantum DXi3500 and DXi5500 User’s Guide 102 Chapter 3 DXi3500 and DXi5500 Remote Management Data Services
De-duplication Policy: Data de-duplication works by recognizing repeated blocklets in a steam of data. Only a single instance of each blocklet is stored and references (tags) are made for all of the duplicate blocklets. These references or tags are stored in an index for use later to reconstitute the de-duplicated data. By only storing one instance of the blocklet, a great deal of capacity is saved. For a virtual tape cartridge, the DXi system waits for 30 seconds of inactivity before a file can be de- duplicated. For a NAS share, the DXi system waits for 60 seconds of inactivity before a file can be de-duplicated. Truncation Policy: Another way the DXi system reduces the amount of filesystem capacity used is to truncate the deduplicated data. Once the deduplicated data is truncated, only the metadata is available on the filesystem. This reduces the amount of capacity required in the filesystem. Once truncated, the file must be reconstituted using it’s tag before you are able to access the file. The DXi waits for a period of inactivity for a file before it truncates the file. For a virtual tape cartridge, the DXi system waits 90 seconds before it truncates the file. For a NAS share, the DXi system waits 120 seconds before it truncates the file. The Space Management page is divided into the following sections: • System Usage • Space Reclamation
System Usage 3
The Space Usage pages allows you to set notifications and define the system usage threshold. The threshold is the percentage of filesystem capacity at which a notification is automatically sent to the user. Crossing the threshold does not stop normal processing. An informational message or trap is sent when the filesystem usages is within 5% of the threshold. A warning message or trap is sent when the threshold is exceeded. To configure space usage: 1 From the Space Management page, click the Space Usage link. The Space Usage page displays (see figure 59).

Critically Low Filesystem Capacity 3
When the filesystem capacity reaches a critically low point, certain steps are taken to ensure that the system remains usable. The thresholds for critically low filesystem capacity is not configurable, but are as follows:
Quantum DXi3500 and DXi5500 User’s Guide 104 Chapter 3 DXi3500 and DXi5500 Remote Management Data Services
• The critically low filesystem capacity threshold is 250 GB. When the free filesystem capacity drops below this level, the system transitions to critically low filesystem handling. • The threshold for transitioning out of critically low filesystem capacity handling and back to normal operations is 260 GB. If the system is operating in critically low filesystem handling mode: • VTL tape cartridge writing is not operational • NAS share writing is not operational • Replication to this system is not allowed and is paused automatically • Truncation of all deduplicated files will proceed, regardless of policy
Space Reclamation 3
The block pool data area of both the DXi3500 and DXi5500 systems is used to store tags that reference deduplicated and replicated data. Tags are used to rebuild a deduplicated file if it needs to be recovered. If this deduplicated or replicated data has been deleted from the system, the tags need to be removed from the block pool so the space can be used for additional reference tags. In the DXi3500 and DXi5500 systems, there are two processes that are used to remove unused reference tags: • Reconciliation - The reconciliation process prepares a list of candidate tags (including reference counts for those tags) to be discarded. These tags represent de-duplicated files that have been deleted from the filesystem or replication sets that have been deleted. Reconciliation takes a few minutes on systems that will not replicate data to target systems or receive replicated data from sources. Reconciliation may take several hours on systems that are replication targets (they must wait for replications in progress to complete). • Reclamation - The reclamation process reviews the list of discarded candidate tags prepared by reconciliation and deletes the tag as many times as required (i.e., until its reference count is zero). Reclamation may take anywhere from a few minutes to a few days, depending on the amount of de-duplicated data to be discarded. When a tag is deleted, the reference counts of the blocklets referenced by it are reduced. When the count of a blocklet becomes zero, the blocklet is
Quantum DXi3500 and DXi5500 User’s Guide 105 Chapter 3 DXi3500 and DXi5500 Remote Management Data Services
discarded and the disk space it occupied is returned to the filesystem for use. To configure space reclamation: 1 From the Space Management page, click the Space Reclamation link. The Space Reclamation page displays (see figure 60).

Data Replication
The DXi3500 and DXi5500 systems can be configured to automatically replicate data on another DXi system as part of a disaster recovery plan. Replication is the process of sending replicated data from a source VTL partition or NAS share to a target VTL partition or NAS share. This process is configurable on a per VTL partition or NAS share basis. The source system must have replication enabled. The target system can store replicated VTL partition or NAS share data for one or more source systems. A system can be both a source (VTL partition or NAS share sending replicated data) and target (receiving replicated data).
Replication The following list provides requirements for replication: Requirements 3 • One to one replication only (a VTL partition or NAS share cannot be replicated to more than one target VTL partition or NAS share). • All source VTL partitions or NAS shares must replicate to the same target system. • Only VTL partitions or NAS shares with de-duplication enabled can be replicated. • All tape cartridges that are in use in a VTL partition and all files that are in use in a NAS share during replication are skipped.
Note: For optimization purposes, the underlying data is continuously updated and will become available when the replication is either run manually or via a scheduled replication.
Quantum DXi3500 and DXi5500 User’s Guide 107 Chapter 3 DXi3500 and DXi5500 Remote Management Data Replication
• It is strongly recommended the replication is set up on a dedicated subnet on Eth port 1 on the DXi3500/DXi5500 system. Data Transmission: Once a replication set has been de-duplicated, it may be replicated (nonredundant data is transmitted from a source system to a target). De-duplication tags representing files with a high probability of being replicated (example: NAS share marked for replication) are queued for replication after de-duplication is complete without regard to the replication schedule. This continuous transmission of data is an optimization allowing replication to be used with low bandwidth networks. Replication Set Transmission and Accounting - When a replication set is scheduled for transmission, the system scans the files comprising the replication set and a namespace file is created. A namespace file contains the complete set of de-duplication tags for the replication set. Data that is active (a NAS file that is open) or data that is not yet de-duplicated is not included in the namespace file. The namespace file is then de-duplicated and transmitted to the target system after the data transmission of the replication set is complete. Once both the replication set and namespace file have been transmitted to the target system, the replication can be recovered. To configure your system for replication: 1 From the Data Services page, click the Replication tab.
Note: Data replication is a licensed feature for the DXi3500 and DXi5500. Contact your Quantum Sales representative for more information on purchasing this option.

NFS Performance 4 For optimal performance it is necessary to use 1000BaseT instead of 100BaseT. On NFS clients, use the vers=3, rsize=262144 and wsize=262144 mount options, and use TCP mounts instead of UDP. When possible, it is also best to utilize TCP Offload capabilities as well as jumbo frames. It is best practice to have clients directly attached to the same network switch as the NFS server. Any routing required for NFS traffic incurs additional latency that impacts performance. It is critical to make sure the speed/duplex settings are correct, because this severely impacts performance. Most of the time auto-detect is the correct setting. Some managed switches allow setting speed/duplex (for example 1000Mb/full,) which disables auto-detect and requires the host to be set exactly the same. However, if the settings do not match between switch and host, it severely impacts performance. For example, if the switch is set to auto-detect but the host is set to 1000Mb/full, you will observe a high error rate along with extremely poor performance. On Linux, the ethtool tool can be very useful to investigate and adjust speed/ duplex settings. It can be useful to use a tool such as netperf to help verify network performance characteristics.
Quantum DXi3500 and DXi5500 User’s Guide 142 Chapter 5 5Implementing a Data Replication Plan
The DXi3500 and DXi5500 can be used as part of your disaster recovery plan through its built in data replication capability. Data replication is used to create another copy of your data on a remote DXi3500 or DXi5500 system. In the event of a disaster where the original data was lost, the replicated data can be quickly recovered from the remote system allowing your business to resume normal operations.
Note: Data replication is a licensed feature for the DXi3500 and DXi5500. Contact your Quantum Sales representative for more information on purchasing this option.
The following sections provide information on setting up data replication and also recovering replicated data: • Setting Up Data Replication • Recovering Replicated Data

Setting Up Data Replication
Setting up data replication on the DXi3500 and DXi5500 consists of the following steps (see figure 79): • Setting Up the Target DXi System • Setting Up the Source DXi System • Enabling and Running Replication
Figure 79 Major Replication Setup Steps
Quantum DXi3500 and DXi5500 User’s Guide 144 Chapter 5 Implementing a Data Replication Plan Setting Up Data Replication
Setting Up the Target DXi Before data can be replicated from a source system to a target system, the System 5 target must be authorized to receive data from a specific source. To authorize a target system to receive data from a source, you must add the source hostname or IP address to the Source Host List on the target system. To add a source hostname or IP Address on a target system: 1 Access the remote management pages on the target system.
Note: For more information on accessing the remote management pages, see chapter 3, DXi3500 and DXi5500 Remote Management.
2 From the Replication page, click the Target Role link. The Target Role page displays (see figure 80).

B Bit The basic unit of data in a binary numbering system (binary digit), represented by a 0 or a 1. Eight bits equals one byte. Byte The basic unit of computer memory which is large enough to hold one character.
C Class A digital device Class A equipment is intended for Commercial installation. Compression The DXi3500 and DXi5500 systems are configured with the Optyon™ hardware-based compression card. With an Optyon card installed in your system, unique data that has been through the de-duplication process can be compressed at a ratio of 2:1. This enables you to maximize the storage capacity of your system as well as increase overall backup performance.
D Data De-duplication Data de-duplication refers to the elimination of redundant data. During this process, duplicate data is ignored, leaving only one copy of the data to be stored. Indexing data is retained and used to restore the previously deduplicated data. Since only the unique data is stored on the system, the amount of required storage space is reduced. DLT Digital Linear Tape technology is owned, developed, and manufactured by Quantum Corporation. DLT tape drives use half-inch wide tape.

H Host The device or devices to which the library is connected.
I In-Line A process (like de-duplication) is running while the data is ingested. IEC The International Electrotechnical Commission is based in Geneva, Switzerland.
L LTO Linear Tape-Open (LTO) technology was developed jointly by HP, IBM and Quantum to provide a clear and viable choice in an increasingly complex array of tape storage options. LTO technology is an "open format" technology, which means that users will have multiple sources of product and media. The "open" nature of LTO technology also provides a means of enabling compatibility between different vendors' offerings. The Ultrium format is the "high capacity" implementation of LTO technology.
