RAID Sets

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

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