Drives - Spectra Logic T-Series Spectra T200 User Manual

Chapter 1 — Library Overview
D
RIVES
The library's drives are installed in modular drive bay assemblies (DBAs).
Each DBA has four drive bays and can accommodate up to four full-height
tape drives or four RXT drives. Drives are hot-swappable to provide
uninterrupted operation.
Each drive is mounted in a drive sled which provides the electrical and
logical connections to the library. The drive sled includes intelligence
which assigns a serial number to the drive based on its location in the
library. This location-based serial number remains constant even if the
physical drive is replaced by a new drive. The new drive simply retains the
designated serial number, so drive replacement is completely transparent
to the backup software.
In addition to the electrical connections for the drive, the drive sled
includes a handle to simplify sliding the drive into or out of a drive bay
and a lock to prevent the drive from being accidentally pulled out of the
library.
