DS8800 model 951 and 95E comparison
With a dual 4-way processor complex, the DS8800 Model 951 supports up to 240
disk drives for a maximum capacity of up to 216 TB. With the introduction of the
900 GB 10k drive and the 3 TB 7.2k drive, the maximum capacities have changed
for the base model (951), and expansion frames. The base model now supports up
to 120 3.5" disk drives for a maximum capacity of up to 360 TB. It also supports up
to 384 GB of processor memory with up to eight Fibre Channel/FICON adapters.
The DS8800 95E is an optional expansion model. Up to three expansion models can
be added. The 95E scales with 3.5" drives as follows:
v With one DS8800 Model 95E expansion units, the DS8800 Model 951 (4-way)
supports up to 288 3.5" disk drives, for a maximum capacity of up to 864 TB,
and up to 16 Fibre Channel/FICON adapters.
v With two DS8800 Model 95E expansion units, the DS8800 Model 951 (4-way)
supports up to 528 3.5" disk drives, for a maximum capacity of up to 1.58 PB,
and up to 16 Fibre Channel/FICON adapters.
v With three DS8800 Model 95E expansion units, the DS8800 Model 951 (4-way)
supports up to 768 3.5" disk drives, for a maximum capacity of up to 2.3 PB, and
up to 16 Fibre Channel/FICON adapters.
The 95E scales with 2.5" drives as follows:
v With one DS8800 Model 95E expansion unit, the DS8800 Model 951 (4-way)
supports up to 576 2.5" disk drives, for a maximum capacity of up to 518 TB,
