Tape drives
The Ultrium tape drive is a high performance streaming tape drive that uses LTO technology. The
library can use Ultrium 460 (LTO 2), Ultrium 960 (LTO 3), Ultrium 1840 (LTO4), Ultrium 3280
(LTO5) and Ultrium 6650 (LTO6) tape drives.
The Ultrium 960 and later include support for both rewriteable and Write-Once, Read-Many
(WORM) tape cartridges. WORM tape cartridges provide an enhanced level of data security
against alteration of data because you cannot erase or overwrite them. To check whether your
backup or archive software application supports WORM tape cartridges, see the following web
site: http://www.hp.com/go/connect.
For optimum performance, always use a tape cartridge that matches the specifications of your
tape drive. You can find comparisons between the Ultrium tape drives in (page 86).
Tape cartridges and cleaning cartridges are specifically formatted for use with Ultrium drives. To
order Ultrium tape cartridges, see “Ordering HP tape cartridges and barcode label packs” (page
102).
Switch for the internal network
CAUTION: Do not connect this switch to your local LAN. It is for internal library use only.
Connecting this switch to the LAN could cause library components to perform incorrectly or report
failures.
The 24-port Ethernet switch provides a private management network to connect the Interface
Manager card to the LTO4 or later tape drives. You must install one switch in each library that
contains LTO4 or later tape drives.
