Integration of Disk
The Spectra T950 library’s TeraPack architecture allows for the addition of RAID
eXchangeable TeraPack (RXT) drives and media.
eXchangeable TeraPack (RXT) drives and media.
RXT drives use an internal RAID controller to write to RXT media packs, each made up
of multiple Serial ATA (SATA) disks sealed in a sturdy protective enclosure. media
packs dock in the RXT drive just like tapes dock in a tape drive, and can be easily
moved off-line and off-site. The media pack is configured with the RAID level you
specify when ordering the media. And the data automatically written using RAID
supplies redundancy to ensure the availability of your data. Using RAID 1, 5, and 1+0
(10) one of the disks in the media pack can fail without any data loss; the failed disk
can be replaced and the data on it rebuilt.

No changes to backup strategy are necessary, because backup software automatically
sees and writes to the disk, recognizing it as an LTO tape drive. This solution lets you
add disk without adding complexity to your backup environment. 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.

RXT drives match the size of a standard LTO (other half-inch tape) drive, so it fits into
the library in a drive sled much like the ones used for tape drives in the Spectra T950
library. RXT media packs have the same form factor as the TeraPack cases used to
transport tapes inside the Spectra T950 library, so the library’s transporter moves disk
packs the same way that it moves tape media.
