Which model should be included with a single frame IBM TS4500 L25?
Which model should be included with a single frame IBM TS4500 L25?
- AAdditional I/O station
- BTop rack with PDU
- CHD2 storage frame
- DAdditional cartridge magazines
Correct Answer:
B
The TS4500 tape library offers high-density (HD), drive-capable and storage-only frame models that are designed to greatly increase storage capacity without increasing frame size or required floor space. The top rack, 3584 Model TR1, provides an extra 10U of rack space on any frame in a library without requiring more floor space.
