Cache memory
The VSP G1000, VSP G1500, and VSP F1500 can be configured with 64 GB to
1 TB of cache memory per controller. The cache memory is installed in one or
two cache path control adapters (CPA). A CPA feature consists of a pair of
redundant blades that are installed and work together to provide cache and
shared memory for the system. The following figure shows two CPAs (2-3,
and 1-4).
Cache memory modules (DIMMs) are available in either 16 GB or 32 GB
sizes. The minimum memory required per controller is 64 GB, either two 16
GB DIMMs or one 32 GB DIMM must be installed in each CPA blade. The
memory modules in a system must all be the same size.
The following table shows minimum and maximum cache capacities per
controller. The figures are doubled for a two-controller system.
