1 Features and overview
The Autoloader provides a compact, high-capacity, low-cost solution for simple, unattended data
backup. This unique design houses up to eight tape cartridges in a compact 1U form factor with
easy access to tape cartridges via two removable magazines and a configurable mailslot. Each
magazine can hold up to four cartridges.
The Autoloader can support Ultrium half-height tape drives. To see the tape drives currently available
for the 1/8 G2 Tape Autoloader, see the MSL QuickSpecs at
www.hp.com/go/tape . For a list of
all supported configurations, go to www.hp.com/go/ebs .
The Autoloader is compatible with most operating systems and environments that support the SAS,
parallel SCSI, or Fibre Channel interfaces. However, the Autoloader requires either direct support
from the operating system or a compatible backup application to take full advantage of its many
features. To verify compatibility, go to
www.hp.com/go/ebs .
The Autoloader uses the interface types described in Table 1 (page 8) . The parallel SCSI Tape
Autoloader uses a single SCSI ID with two logical unit numbers (LUNs) — one for the tape drive
and the other for the robotic.
