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. 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 Sleds 1

Each drive sled located on the front of the DX-Series storage array

contains one hard drive.

DX-Series

Controller

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

figure 4).
