Chapter 1: DXi4701 System Description Overview

Overview

The DXi4701 is Quantum’s entry level and midrange disk backup solution that integrates data deduplication and replication technology to connect backup and DR (disaster recovery) protection across distributed corporate environments. The DXi4701 disk-based backup appliance uses Quantum’s patented data deduplication technology to increase disk capacities by 10 to 50 times, and make WAN replication a practical, cost-effective part of disaster recovery planning. With Capacity-on-Demand scalability from 5 TB up to 135 TB, the DXi4701 is designed for departmental and medium business customers.

Advanced Data Deduplication Increasing Disk Retention for Backup Data

The DXi4701 leverages Quantum’s patented data deduplication technology (U.S. Pat. No. 5,990,810) to dramatically increase the role that disk can play in the protection of critical data. With the DXi4701 solution, users can retain 10 to 50 times more backup data on fast recovery disk than with conventional arrays.

Remote Replication of Backup Data Providing Automated Disaster Recovery Protection

With the DXi4701, users can transmit backup data from a remote site to a central, secure location to reduce or eliminate media handling. DXi™-Series replication is asynchronous, automated, and operates as a background process.

Enterprise Features Provide Secure Repository

The DXi4701 features Capacity-on-Demand scalability from 5 TB up to 135 TB. The DXi4701 offers two options for storage presentation:

• DXi4701 NAS Configuration - Presents storage as NAS shares (CIFS and NFS) or OST storage servers.

• DXi4701 VTL Configuration - Presents storage as VTL (virtual tape library) partitions.

2 Quantum DXi4701 User’s Guide

DXi Accent distributes deduplication between the DXi4701 and the backup server to accelerate backups over bandwidth-constrained networks. Compatibility with Quantum's vmPRO software provides consolidated support for backup of physical and virtual servers.

In addition, DXi4701 systems optionally support Data-at-Rest Encryption to secure all data stored on the DXi4701. Data-at-Rest Encryption ensures that a hard drive that is physically removed from the DXi4701 cannot be read using another system or device

DXi4701 Replication on

Chapter 1: DXi4701 System Description

What’s New in DXi 2.3 Software

• Replication Send Page - The redesigned Replication > Send page lets you easily manage data replication for all shares or partitions. In addition, you can quickly enable or disable replication for one or more shares or partitions (see

Replication Send on page 122).

• OST Status Page - The enhanced Status > OST page provides statistics for recent OST optimized duplication as well as DXi Accent activity (see

OST Status on page 188).

• Replication Configuration Page - The redesigned Configuration > Replication page allows you to manage both replication targets and sources using a single, unified interface (see

Replication

Configuration on page 249).

• Increased Replication Snapshots - You can retain up to 32 snapshots for each share or partition configured for replication (see

Changing the Maximum Number of Snapshots on page 259).

• Scheduler Page - The redesigned Configuration > Scheduler page provides tools for quickly adding a new scheduled event, as well as for managing schedules for multiple shares or partitions (see

Scheduler on page 292).

Enhancements in Previous Releases

• Network Address Translation (NAT) - You can specify a NAT IP address for the DXi to enable replication across a public network, when the source and target are located behind NAT-enabled routers (see

Network on page 303).

• Software Upgrade Utility - The Software Upgrade Utility can automatically check for software upgrades for your DXi system. If an upgrade is found, you can choose to download and install it to update your DXi to the latest software version (see

Software

Upgrades on page 382).

• Chargeback Reporting - DXi Advanced Reporting (included with DXi 2.3 Software) enables per share reporting, also called chargeback reporting. Using the chargeback reports, you can see ingest, incoming replication, and outgoing replication statistics for individual CIFS/NFS shares or OST LSUs (for more information, see the Quantum DXi Advanced Reporting User’s Guide (6-67353).

The following enhancements were introduced in DXi 2.2.x Software:

• Site Map - The User Interface Site Map displays a visual map of all management pages in the DXi remote management console. Use

activities performed by administrative and service users in the past 90 days. You can view the user who performed the activity, the time the activity was performed, and other information. You can also download the activity log to an XML file (see

Activity Log on

page 189).

NetBackup 7.1 or higher, you can configure an LSU for Automatic Image Replication. If enabled, data on an LSU is automatically replicated to a remote LSU that resides on a DXi in a different NetBackup domain (see

Replicating OST Data on page 261).

Duplication, as data is written to the storage server, it is simultaneously replicated to the target DXi. When optimized duplication or Automatic Image Replication subsequently occurs, the operation is more efficient because a portion of the required data has already been replicated to the target storage server (see

Replicating OST Data on page 261).

• DXi Accent Improvements - DXi Accent supports Windows based media servers running Symantec Backup Exec or NetBackup. In addition, data sent from the media server to the DXi can be encrypted using AES (Advanced Encryption Standard) encryption methods (see

DXi Accent on page 289).

• Consolidated Job Scheduler - All scheduled functions of the DXi are now managed on the Scheduler page, including the scheduling of replication, replication throttling, e-mail reports, healthchecks, and space reclamation (see

Scheduler on page 292).

• VLAN Tagging - You can enable VLAN tagging and Jumbo Frames for any configured network interface on the DXi (see

Network on

page 303).

• Space Reclamation Improvements - Scheduled and on demand space reclamation has been tuned for increased performance, while automatic space reclamation during low space conditions provides maximum free space recovery. Also, the blockpool automatically reuses free bytes when ingesting data (see

Space Reclamation on

page 371).

6 Quantum DXi4701 User’s Guide

Chapter 1: DXi4701 System Description

What’s New in DXi 2.3 Software

• Secure Shred - With Secure Shred, you can securely and permanently erase sensitive data stored on the DXi. To securely erase data, first delete files on NAS shares or storage servers, then start secure shred. During secure shred, all residual data associated with the deleted files is securely erased from the disk drives and is overwritten with random patterns (see

Secure Shred on page 379).

The following enhancements were introduced in DXi 2.1.x Software:

• Additional OpenStorage (OST) Improvements - Enhancements include support for optimized synthetic full backups, and support for HP-UX 11i v3 IA-64 platforms (NetBackup only).

• Replication Throttling and Scheduler - With replication throttling, you can configure the DXi to limit its outgoing data replication bandwidth to a specified maximum in order to avoid network contention. Use the new Scheduler page to set up a recurring schedule for replication throttle, and to manage schedules for space reclamation and healthchecks.

• AES 256-bit Encryption - When sending replicated data to a target system, the DXi can take advantage of 256-bit encryption for stronger security.

• New CLI Functionality - The command line interface (CLI) supports new and updated functionality for enabling symlinks and hard links on NAS shares, enabling SMB server signing for NAS shares, mapping OST IP addresses, scheduling replication throttling, and performing advanced configuration of network interfaces.

• Improved Space Reclamation Process - The space reclamation process now better adjusts its use of system resources, consuming fewer resources during data ingest and performing space reclamation more quickly when more system resources are available.

The following enhancements were introduced in DXi 2.0.x software:

• Inline Data Flow - The new, inline data flow enabled by the DXi

2.0.x Software deduplicates data as it is ingested into the DXi appliance. Optimized for the new generation of purpose-built DXi hardware platforms, it provides enhanced performance and more efficient dynamic use of system resources (see

Data Reduction on

page 8).

• OpenStorage (OST) Improvements - Enhancements include increased total performance, including writes, reads, and replication; simplified deployment (see

Quantum DXi4701 User’s Guide 7

Data Reduction

Data reduction is the process of reducing the amount of storage capacity required to store your data. The DXi4701 systems provide two techniques to optimize the storage space required on your system:

• Data Deduplication

8 Quantum DXi4701 User’s Guide

Chapter 1: DXi4701 System Description

Data Reduction

• Compression

Data Deduplication The DXi-Series disk backup and replication systems use Quantum’s

patented data deduplication technology to dramatically increase the role that disk can play in data protection. With DXi-Series solutions, users can retain 10 to 50 times more backup data on fast recovery disk than with conventional arrays. This advantage allows IT departments to cost-effectively retain months of backup data on disk for faster, more reliable restores and more data recovery points. Quantum’s innovative implementation of this core technology means that users do not have to compromise on performance to take advantage of extended retention capability. The new, inline data flow in the DXi 2.x Software provides streamlined deduplication that offers a maximum combination of total system performance, manageability, and value.

Quantum's deduplication technology uses a sub-file, variable-length approach to identify redundant blocks in a data stream—blocks that have appeared before in the same dataset or in datasets processed at an earlier time. When a block appears that has already been stored, the DXi system inserts a reference pointer to the earlier instance of the data segment instead of storing another copy. The result is a dramatic reduction in the storage capacity needed to store the data set, and a similar reduction in the bandwidth needed to replicate deduplicated data sets over a network. For more information on enabling data deduplication, see

NAS Summary on page 204.

Compression The DXi4701 systems use compression technology after duplicate blocks

have been identified and replaced as part of the deduplication process. With compression, unique data that has been through the data deduplication process can be compressed at a typical ratio of approximately 2:1. This enables you to maximize the storage capacity of your system.

Quantum DXi4701 User’s Guide 9

Chapter 1: DXi4701 System Description Space Reclamation

Space Reclamation

The space reclamation process performs multiple functions on the DXi4701.

When data is deduplicated it is stored in a block pool—a pool of all unique data blocks that were captured during the data deduplication cycle. When subsequent backup jobs occur, the data deduplication engine searches for new data entering the DXi and uses a variable length compression algorithm to compare new data to existing data in the block pool. Unique blocks are added to the block pool and known blocks are indexed.

The space reclamation function searches the blockpool for data blocks that are not referenced by any pointers (that is, the files associated with the block have been expired and removed). Once such a data block is identified, the block is removed to make the space reusable.

For correct system operation, space reclamation must be run at regular intervals (at least once a week). Quantum recommends creating a schedule to automatically run space reclamation (see

Reclamation on page 301).

Scheduling Space

It may be beneficial to schedule space reclamation for a time when other operations are not normally being carried out. Therefore it is important to know when to schedule the space reclamation process. As best practice it is recommended that this process commences at least two hours after your backup job has completed on a daily basis. It is far more efficient to process a day’s worth of new data than a week’s worth.

Remote Replication

Today most backup occurs on isolated devices, making it difficult to deploy disk backup when disaster recovery protection is required. DXiSeries solutions use data deduplication and replication to decrease by up to 50 times the bandwidth required to move backup data over networks and between sites. This dramatic gain makes it practical and cost-effective for users to replicate backup data over WANs for secure,

10 Quantum DXi4701 User’s Guide

network-based disaster recovery protection, and it lets users combine rapid, local restores with sound disaster recovery protection.

With DXi-Series replication, users can transmit data from a single site or multiple sites to a central location using any DXi model. DXi-Series replication is an asynchronous, automated background process that includes encryption of data in transit. This model for protecting the distributed enterprise allows users to combine disk, replication, and tape for an optimal combination of performance, simplicity, and security.

For more information on implementing a replication plan, see

Chapter 6, DXi4701 Replication.

Note: A DXi4701 can only replicate data to a DXi that supports the

same protocol as the DXi4701 (NAS or VTL). That is, a DXi4701 NAS system can only replicate data to a DXi that supports NAS. Similarly, a DXi4701 VTL system can only replicate data to a DXi that supports VTL.

DXi4701 System

The DXi4701 (see Figure 1) includes the following features:

Hard Drive Storage

The DXi4701 system is based upon high speed disk drives instead of tape drives (see

• DXi4701 VTL configurations present the drive storage area as VTL partitions (see

• DXi4701 NAS configurations present the drives storage area as NAS shares or OST LSUs (Logical Storage Units) (see

HDDs on page 13). The usable capacity is 5–135 TB.

Virtual Tape Storage on page 15).

Network Attached

Chapter 1: DXi4701 System Description

Hard Drive Storage

By making use of high speed drives, the DXi4701 greatly reduces the time required for backup/restore functions and improves confidence in completing the backup in the time allowed.

DXi Usage Scenarios

DXi storage presentations are optimized for backup usage rather than file sharing. Backup application usage is typically characterized by:

• Aggregated name spaces and file contents.

• Limited direct, active file access.

• Limited browsing, scanning, or stating.

• Limited metadata manipulation (including rename).

Usage diverging from these characteristics must be qualified to ensure acceptable behavior with respect to functionality, performance, replication, and recovery.

Note: Using Backup Exec with GRT (Granular Recovery Technology)

over CIFS is not recommended usage. GRT requires frequently overwriting portions of and appending data to existing files, which is inconsistent with the DXi usage scenarios. Instead, Quantum recommends using OST.

HDDs Depending on the configuration, the DXi4701 Node supports 6 or 12

high capacity (4 TB) hard disk drives (HDDs) (see hard drives are used for the operating system, system software, and indexes needed for data deduplication, replication, space reclamation.

The DXi4701 Expansion modules (JBODs) each support 12 high capacity (4 TB) hard disk drives (see

are used for data storage.

All hard disk drives are mounted and pre-assembled in drive carriers (see

Hard Drive Storage

Virtual Tape Storage A virtual tape storage or virtual tape library (VTL) presentation 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 tape library, with virtual cartridges, virtual drives, and a virtual changer mechanism. A DXi4701 can be configured to present multiple VTL interfaces of different sizes and types at once. This allows backup applications to recognize and integrate a DXi series system into a data center environment just like one or more physical tape libraries.

Quantum DXi4701 User’s Guide 15

Chapter 1: DXi4701 System Description Hard Drive Storage

Figure 5 VTL Example

Virtual Media—How Many and What Size?

There is no correct answer to this question as it really depends on your backup regime and the backup application in use. A DXi system does not preallocate disk space when a virtual tape cartridge is created, there can be an inclination to create a lot of large virtual tape cartridges, greater than the amount that is actually required. While this has no initial bearing on the DXi’s capacity utilization, it can cause issues down the track.

Regarding the quantity of virtual media you need to create, as long as there is sufficient media to hold the amount of backup data for the required retention period, the quantity does not really matter. However, it is extremely important, as mentioned earlier, that the aging and expiry rules of the media pool are defined early. If these rules are not defined, the virtual tape cartridges will never enter the scratch pool resulting in you running out of virtual media, and in turn space on the DXi system. As a rule of thumb, more is better than less; as long as expiry rules are defined.

Although there is no perfect size when it comes to creating virtual tape cartridges, there are a few factors to consider. If a virtual tape cartridge

16 Quantum DXi4701 User’s Guide

Chapter 1: DXi4701 System Description

Hard Drive Storage

is created at 200 GB, then it will be presented as storing 200 GB of native data.

Creating smaller sized media is preferred, for example 50 GB or 100 GB, as it allows a virtual tape cartridge to be completely filled even when backing up smaller data sets. Smaller sized media also aids the transfer of data from virtual to physical tape platforms. Once again, virtual tape cartridge size will depend on the backup application in use.

It is important to note that the design of the DXi will not allow a virtual tape cartridge to be written to it if its size is larger than the amount of free space available on the DXi. For example, if you have a virtual tape cartridge size of 400 GB but only 300 GB of free space is available on the DXi, the backup will fail when attempting to write data to the virtual tape cartridge. As a result, smaller virtual tape cartridge sizes are better.

Remember, the DXi system is always cautious of being filled up so that the integrity of stored data is not compromised.

Network Attached Storage (NAS)

The DXi4701 system has the ability to serve as a NAS backup system (see

Figure 6) where the following protocols are supported:

• CIFS Protocol

• NFS Protocol

CIFS Protocol

The CIFS (Common Internet File System) protocol defines a standard for remote file access from many computers at a time in Windows environments. This protocol allows users with different platforms to share files without installing additional software.

Active Directory Support

The DXi4701 supports ADS (Active Directory Services) as well as ACLs (Access Control Lists). This provides the following benefits:

• Compatibility with CIFS domains - NAS shares are able to join CIFS domains and use domain authentication.

• Precise control of file system permissions - Administrators can specify which users and groups can perform what actions.

NFS Protocol

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 and Linux networks. It can also be used with Windows networks.

Windows 2008 R2 are supported for Active Directory domain membership.

same as the default permissions for a Windows 2003 share with the addition of an ACE (Access Control Entry) that permits full access to the share for all authenticated users. Administrators can choose to remove this full access ACE, set up custom permissions, or leave the ACL (Access Control List) as is if the server is set up in a fully trusted environment.

Chapter 1: DXi4701 System Description

Hard Drive Storage

OpenStorage (OST) With the OST presentation, the DXi system presents storage servers to a

Symantec NetBackup or Backup Exec media server through a specific Symantec protocol. A storage server consists of logical storage units (LSUs), which are similar to directories in a NAS file system.

The OST presentation requires the Symantec NetBackup (6.5.3 or later) or Backup Exec 2010 or later host application and the OST Plug-in client installation on the media server. Plug-in clients are host-OS dependent and are supplied by Quantum. To use the DXi in OST mode, you must configure an OST storage server and LSUs on the DXi. You must also map the LSUs on the NetBackup server so that NetBackup can perform backups and restore from them. Additionally, policies for optimized duplication (OST replication) and OST direct to tape may need to be set on the NetBackup server.

Supported RAID Configurations

RAID is short for Redundant Array of Independent (or Inexpensive) Disks, which is a category of storage that employs 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, 6 and 10. The DXi4701 uses RAID 6.

RAID 6 Configuration

RAID 6 uses block-level striping with two parity blocks distributed across all member disks. Dual parity provided by a RAID 6 configuration ensures that your data retains full integrity even in the event of two hard drive failures. Since single parity RAID levels are vulnerable to data loss until the failed drive is rebuilt: the larger the hard drive, the longer the rebuild will take and the longer the system is vulnerable to possible data loss.

The DXi4701 Node and Expansion modules (JBODs) use RAID 6 volumes for data storage (see

Figure 8 and Figure 9):

• DATA - HDD slots 1–11 (data storage)

• Hot Spare - HDD slot 0

Note: The hot spare drive is initially located in slot 0. If a hard drive is

replaced, the replacement drive becomes the new hot spare.

Network Configuration

During network configuration, each individual interface on the DXi4701 can be configured as a subnet with its own network settings. Each physical Ethernet port can be configured as an interface. In addition, you can also create bonded interfaces (logical ports) consisting of two or more physical ports.

Keep in mind that any traffic can pass through any of the configured Ethernet ports. This means that the routing of different traffic types, as well as firewall capability, must be controlled using the network infrastructure (routers and switches) that the DXi4701 is connected to.

available slots in the initial location. For example, if 50 I/E slots are available, you cannot create more than 50 cartridges if the initial location is set to I/E Slot.

• Number of Media - The number of cartridges to create in the partition.

• Starting Barcode - The first barcode number in the cartridge sequence.

You can enter any alpha-numeric string for the starting barcode. Subsequent barcodes are incremented accordingly. For example, if you enter AA, the cartridges are numbered AA0000, AA0001, AA0002, and so on. If you enter a starting barcode with less than 6 characters, zeroes are appended to the barcode to make it 6 characters long.
