Entry Tape Autoloader
The IBM 3581F28 is a new 2U rack-mountable tape autoloader built around a single LTO-2 drive. It provides 1.6 TB native capacity per cartridge and 3.2 TB compressed capacity across eight slots. The unit targets small to midsize environments that need automated, unattended backup without the complexity of a full library.
Fibre Channel Rack Integration
The autoloader connects through a Fibre Channel interface and fits a standard 19-inch rack with a depth of 34 inches and a height of 3.5 inches. One drive handles all eight cartridges sequentially, freeing staff from manual tape swaps while keeping cabling and power requirements to a single drive module.
Suited For Predictable Batch Workloads
Organisations with stable data sets that fit within the 1.6 TB native or 3.2 TB compressed per cartridge envelope will find the slot count adequate. Buyers who need simultaneous multi-stream restores, higher native throughput than 40 MB/s, or capacity beyond eight cartridges should evaluate larger library configurations.

- 6 TB native capacity per LTO-2 cartridge
- 40 MB/s native transfer rate for steady throughput
