DS8300 (Models 922, 932, 9A2, and 9B2)
IBM System Storage DS8300 models (Models 922, 932, 9A2, and 9B2) offer higher
performance and capacity than the DS8100. Models 9A2 and 9B2 also enable you
to create two storage system LPARs (images) within the same storage unit.
All DS8300 models offer the following features:
v Dual 4-way processor complex
v
Up to 128 disk drives, for a maximum capacity of 64 TB
v Up to 256 GB of processor memory (cache)
v Up to 16 fibre-channel/FICON or ESCON host adapters
The DS8300 base models can support up to four expansion models. With expansion
models, you can expand the Models 922, 932, 9A2, and 9B2 as follows:
v
With one expansion model, you can support the following expanded capacity
and number of adapters:
– Up to 384 disk drives, for a maximum capacity of 192 TB
– Up to 32 fibre-channel/FICON or ESCON host adapters
v With two expansion models, you can support the following expanded capacity:
– Up to 640 disk drives, for a maximum capacity of 320 TB
v With three expansion models, you can support the following expanded capacity:
– Up to 896 disk drives, for a maximum capacity of 448 TB
v
With four expansion models, you can support the following expanded capacity:
– Up to 1024 disk drives, for a maximum capacity of 512 TB
Figure 4 on page 6 shows the configuration of a Model 922, 932, 9A2, or 9B2 with
two expansion models. Each of these models can attach up to four expansion
models. Models 922 and 932 can attach to the 92E expansion models. Models 9A2
and 9B2 can attach to the 9AE expansion models.
