Overview 1

The DX-Series 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

Time Required for Backup

Confidence in Completing the Backup

Time to Restore Data

Not only is the amount of data that needs to be backed up growing by nearly 100% per year, but 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 completing the backup job within the backup window can 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.

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.

Chapter 1 DX-Series System Description

DX-Series System

DX-Series System 1

The DX-Series system solves these problems by separating the backup target (servers) from the backup archive (tape libraries). The DX-Series system takes advantage of high speed hard drives to greatly reduce the time required for backup/restore functions and also improve confidence in completing the backup in the time allowed. The data stored on the DX-Series system can then be migrated to a tape library without utilizing valuable network resources.

The DX-Series system consists of the DX30 and DX100 devices. Both are backup devices based upon high speed disk drives instead of tape drives.

The DX30 consists of:

• A single controller and 1 to 4 storage arrays

The DX100 consists of:

• A single controller and 2 to 16 storage arrays

• One or two Fibre Channel switches

• An Ethernet switch, and two or more AC power sequencers

The system emulates an ATL P1000 library with up to 24 virtual digital linear tape (DLT™) 7000 tape drives (see figure 1 DLT7000 tape drives for DX30.

Note: The ATL P1000 library emulation is an inquiry string only and

can be configured via the remote management interface (see

Chapter 3

operates with all backup applications allowing the DX-Series system to integrate seamlessly in a data center.

Chapter 1 DX-Series System Description DX-Series System

Note: The DX-Series storage array is shipped with the following

RAID configuration:

• 1 LUN configured in RAID 5 (7 data drives + 1 parity

• 1 LUN configured in RAID 5 (6 data drives + 1 parity

• 1 global hot spare drive

To reconfigure the DX-Series storage array to either remove the hot spare or add an additional hot spare (total of two hot spares), contact Quantum customer support (see Customer

Support on page xvi). Reconfiguring the storage array RAID

configuration will cause all previously stored data to be lost.

Both the DX30 and the DX100 use the same system components (controller and storage arrays). The DX100 storage arrays, however, contain dual RAID controllers and the overall DX100 system can expand to sixteen storage arrays. The DX100 controller also has a full compliment of Fibre Channel HBAs (two quad port HBAs and four dual port HBAs) whereas the DX30 has two Fibre Channel HBAs (a single quad port HBA and a single dual port HBA).

Chapter 1 DX-Series System Description DX-Series System

Serial ATA hard drives are the heart of the DX-Series system. These hard drives (1 drive per drive sled = 16 total drives) appear to the backup application as up to 160 DLT tape cartridges per storage array (see

figure 2

Data is stored on the hard drives through an interface that appears as an ATL P1000 tape library. This allows backup applications to recognize and integrate a DX-Series system into a data center environment just like a typical tape library.

Caution: Removing hard drives during system operation may cause

loss of data or degraded system performance. Contact Quantum customer support (see report any hard drive failure.

RAID Sets 1

The DX-Series storage array is divided into two RAID sets. The first RAID set is made up of the first eight drive sleds (sleds 1-8). The second RAID set is made up of the next seven drive sleds (sleds 9-15). The last hard drive (drive sled 16) is reserved as a global hot spare. Each RAID set can sustain a single drive sled failure and can hold a maximum of 80 virtual tape cartridges. A maximum of 160 virtual tape cartridges are held within a storage array.

Drive Sleds 1

Each drive sled located on the front of the DX-Series storage array contains one hard drive.

The DX-Series controller contains a Linux based operating system that provides the library and tape drive emulation as well as Fibre Channel

and Ethernet interfaces (see

This connection can be a direct connection to the Fibre Channel host or to a Fibre Channel switch. The Fibre Channel interface automatically detects the mode being used by the network and sets itself appropriately.

Fibre Channel Switch (DX100 Only)

Figure 5 Fibre Channel Switch

The Fibre Channel switch provides twenty ports for connecting up to eight storage arrays to the DX-Series controller. Each storage array has two connections to the Fibre Channel switch for redundancy and

improved performance. One Fibre Channel switch is required for two to eight storage arrays; a second Fibre Channel switch is required for nine to sixteen storage arrays (see

figure 5).
