The ETERNUS LT40 S2 tape library is a compact, high-performance and low-cost device for mounting in a rack for the purpose of simple and automatic data backup. It is available for the SE server in two variants:
ETERNUS LT40 S2 with FC or SAS connection and one or two half-height LTO-5 drives
ETERNUS LT40 S2 with FC connection and one or two half-height LTO-6 drives
ETERNUS LT40 S2 tape libraries can be be integrated into the SE server when required:
Up to two systems can be connected to an SU300.
On an AU up to two systems can be connected to one controller.
In this chapter the ETERNUS LT40 S2 tape library is referred to as “the tape library” for short.
In both variants ETERNUS LT40 may contain one or two disk drives and one or two removable magazines. The left-hand magazine has an import/export port (I/E port - this is referred to as the mailslot below). Each magazine can contain up to twelve magnetic tape cartridges. If the mailslot is activated, the number of usable slots for storing MTCs is reduced by three.
During BS2000 operation the mailslot is always activated, i.e. depending on the license 9 or 21 cartridge slots are available for BS2000 operation.
An integrated robot loads and unloads the drives. A barcode reader is integrated into the robot units, which enables the tapes to be addressed by means of the names on the labels of the cartridges.
