Does compaction ratio mean compression in 3PAR?

[dennischen]

Hi Everyone,

I'm new to 3par. In the IMC, what does the compaction ratio mean? And how is it caculated to 3.627:1.  I suspect it's compression. But seems like there isn't any compression option I can enable or disable.  Thanks for the guiding.

Hi dennischen,

It's not compression. It's your overall savings from thin provisioning. See page 22 of this doc:

Oh, make sense. Thanks for the help. 

And still another question, can I enable compression in 3par 3.2.1 & 3.2.2? I haven't found any compression configuration.

Hi,

compression is only for SSD and comes with the new 3.3.1 Firmware.

And Deduplication that is already possible needs SSD Disk too.

So - No, sorry you have FC Disks only

Get it. Thanks for the answer.
