IBM 3590-B11 Enterprise Tape Autoloader

The IBM TotalStorage Enterprise Tape Drive 3590 Model B11 is the rack-mountable model that includes a 10-cartridge Automatic Cartridge Facility (ACF) that can be used in a random access mode as a mini-library. Up to four 3590 Model B11 Tape Drives can be installed in a rack, thus reducing the floor space required. The ACF can be quickly loaded with a new magazine. This model includes an integrated SCSI-3 controller with two ports that support a 16-bit, fast-and-wide, Ultra SCSI differential interface. It can also be mounted in an IBM TotalStorage Enterprise Tape Drive Frame 3590 Model A14 with the IBM TotalStorage Enterprise Tape Controller 3590 Model A60 for non-library attachment to ESCON or FICON channels. The Model B11 tape drive has a 9 MB/second native data rate (with compression up to 27 MB/second sustained data rate).
