We’ve been setting up Active Directory Federation Services (ADFS) on Windows Server 2012 R2 to tie up with Office365, and we ran into a snag with load balancing ADFS on our aging F5 BIG-IP LTM. It’s on the dinosaur end of the historical timeline, or to put it another way, “it’s in its sunset year”, and the latest supported code is 10.2.4.

This poses a bit of an issue with monitoring the ADFS servers, since the version shipping with Windows Server 2012 R2 includes a new SSL TLS feature called “Server Name Indication”, or SNI. The prehistoric 10.2.4 BIG-IP code doesn’t support SNI. Thankfully, Microsoft provides a way to monitor the servers over HTTP (instead of HTTPS), but the documentation we found–links below–was lacking an important detail.

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 theĀ actual deduplication ratio?
