HP 3PAR recently released version 3.2.1 of the InForm OS, which most notably brought in-line deduplication to the already rock-solid storage platform. Last week, I wrote briefly about it and included screenshots of estimates in the CLI. Today, I’d like to share real-world results.
I’d like to give particular thanks to Ivan Iannaccone of the HP 3PAR team for reaching out and for early access to the 4.6.1 IMC with dedupe in the GUI.
After I ran the estimate in the previous post, I learned from Ivan that estimates (and jobs) of multiple virtual volumes (VVs) in the same common provisioning group (CPG) will return increased data reduction ratios (read: less used space). Thus, when I received the new InForm Management Console (IMC) yesterday, I ran a new estimate against two VDI (Microsoft RemoteFX) VVs to see how the numbers panned out.
As you can see, the dedupe ratio rose from 2.31 to 2.83. Every little bit helps, but what is the actual deduplication ratio?
