Compression accelerator

The optional compression coprocessor adapter increases the speed of I/O transfers to and from compressed volumes.

You can optionally install 1 or 2 compression accelerator adapters in a SAN Volume Controller 2145-SV1 or SAN Volume Controller 2145-DH8 node. Each compression accelerator increases the speed of I/O transfers between nodes and compressed volumes. You must install at least one compression accelerator if you configured compressed volumes.
