The IBM-SP was initially aquired in January 1998. The IBM-SP is made up of an IBM SP2, an IBM SSA Array, and an IBM 3494 Tape robot unit. The initial configuration consisted of 1 Computing frame with 1 High node and 6 thin nodes, 2 SSA sleds each with 16 9 GB drives with a total capicity of 288 GB and 3 cabinets for the 3494 tape robot with 4 Tape drives.

In January 1999 the system was expanded.The new components were 3 silver nodes for the computing frame, 2 SSA sleds each with 16 18GB drives, and two more Tape drives for the 3494. As it stands the system has 10 nodes with a total of 16 processors, over 800 GB in SSA disk storage and over 8000 GB in Tape storage. The tape drives were later upgraded to increase storage to over 16Tb.


Past Data warhousing wasdone primarily though IBM's High Performance Storage System (HPSS). This allows for the awsome storage capacity of a large Tape robot, without all the hassles normally associated with such a warehouse.

The SP2 is currently undergoing reconditioning.
