This section provides the basic specifications for Spectra Logic RXT150
drive and media packs supported by the libraries. RXT drives bring RAID-
protected disk storage to the traditional tape library environment without
adding complexity to the backup environment. The RXT drives use an
internal RAID controller to write data to RXT media packs.
RXT150 drives are the same size as a standard full-height tape drive. They
mount into a drive sled similar to the ones used for the tape drives.
RXT media packs can be removed and stored as appropriate for your
backup strategy, while still providing the reliability of disk and the
redundancy of RAID (Redundant Array of Independent Disks). For a brief
overview of RAID, see

RXT Drive Transfer Rates

The drives in an RXT media pack achieve native transfer rates of up to
110MB/sec when configured as RAID 0 in an optimal environment (that is,
with an optimal data source and optimal performance from the server
connected to the RXT drive). The RAID level configured on the RXT media
pack, its network configuration, and the use of data compression will affect
the transfer rate.
