5 Installing the tape library

5.1 AP Series TL4000 4U tape library features and requirements

The AP Series tape library provides a compact, high-capacity, low-cost solution for simple, unattended

data backup. This unique design houses up to 48 tape cartridges in a compact 4U form factor with easy

access to tape cartridges via two removable magazines and a mailslot. The magazines can hold up to

twelve (left magazine including mailslot) and twelve (right magazine) cartridges.

The library can support up to four LTO3 half height tape drives, two LTO3 full height tape drive or two

LTO4 full height tape drive. The library occupies one SCSI target address (for the single drive version)

and uses dual LUNs for the tape drive and library robotic.

The AP Series tape library is compatible with most operating systems and environments that support

the SCSI interface. However, the library requires either direct support from the operating system or a

compatible backup application to take full advantage of its many features.
