Overview
Overview1
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
1
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
1
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
1
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 System1
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.

system to integrate seamlessly in a data center.
Note:The DX-Series storage array is shipped with the following
RAID configuration:
• 1 logical drive configured in RAID 5 (7 data drives + 1
• 1 logical drive configured in RAID 5 (6 data drives + 1
• 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 xvii). 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).

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 DLT tape cartridges (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.

RAID Sets1
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. Both RAID sets
contain 2 LUNs or logical units. Each RAID set can sustain a single drive
sled failure and can hold a maximum of 160 virtual tape cartridges (80
cartridges per LUN).
Drive Sleds1
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
1
and Ethernet interfaces (see
