For ``hpe3par:compression`` key, the HPE 3PAR StoreServ Storage array must meet
the following requirements:
* Firmware version HPE 3PAR OS 3.3.1
* HPE 3PAR Storage system with 8k or 20k series

* Supported only on Solid State drives
* The assigned CPG for a compressed volume must be set to device type of "SSD"
Other restrictions and considerations for ``hpe3par:compression``:
- For a compressed volume, minimum volume size needed is 16 GB; otherwise
resulting volume will be created successfully but will not be a compressed volume.
- A full provisioned volume cannot be compressed,
if a compression is enabled and provisioning type requested is full,
the resulting volume defaults to thinly provisioned compressed volume.
