Compression in HPE 3PAR Web Services API 1.6.4

Shravan2 — Mon, 04 Feb 2019 12:38:15 GMT

I was looking for HPE 3PAR Web Services API 1.6.4 for compression on Threepar Arrays and found the volume TUNING API with the compression option.

Questions:

1. Does Volume Compression work only when the compression is enabled on a whole array?

2. I am seeing a different type of volume provisions namely TVPP, TDPP, FULL and so on. Is the compression option limited to certain type of volumes?

3. What exactly is userCPG. Is it just a user-defined name while you compress a volume?

Hello Shravan2,

1. Does Volume Compression work only when the compression is enabled on a whole array?

You can chose to enable compression for a particular volume. Please keep in mind that they should be part of SSD CPGs to get this feature worked and not part of the feature AO.

2. I am seeing a different type of volume provisions namely TVPP, TDPP, FULL and so on. Is the compression option limited to certain type of volumes?
Compression option available for thin volumes (TPVV/TDVV)

3. What exactly is userCPG. Is it just a user-defined name while you compress a volume?

The user CPG is the one in which the VVs will be created or part of.
