IBM 3584-D53 TS3500 Library Expansion Frame

The IBM 3584 TS3500 Tape Library Model D53 expansion frame is designed for IBM TS1030 LTO Ultrium Fibre Channel Tape Drives and LTO data cartridges. Up to 15 Model D53 expansion frames may be added to the TS3500 Tape Library Model L22, L23, L32, L52, or L53 base frame to increase LTO cartridge storage or drive capacity. Each Model D53 supports up to 440 LTO cartridge slots and up to 12 IBM LTO Ultrium 3 Tape Drives, with an incremental reduction of storage slots for each set of four tape drives installed. Each frame can have up to 12 logical libraries or 12 control paths (one per tape drive).
