HP EML E-series Tape Libraries - Manual (Page 29)

Load ports and magazines
The load ports are mechanical devices on the front of the library that enable you to import and export
tape cartridges to and from the library through removable magazines, or act as additional library
storage slots. These two functions for a load port cannot be mixed; you must either designate an entire
load port to be import/export slots or storage slots. The base module contains a load port capable of
using one 5-cartridge magazine. The 8U expansion modules contain load ports capable of using two
5-cartridge magazines each.

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), and Ultrium 1840 (LTO4) tape drives.

Figure 14 LTO tape drives
The Ultrium 960 and Ultrium 1840 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:

For optimum performance, always use a tape cartridge that matches the specifications of your tape drive.
Table 3 on page 30 shows tape drive compatibility and tape capacity. You can find other comparisons
between the Ultrium tape drives in Table 32 on page 105.
