5.5 Update 1 Release Notes

vSphere 5.5 Update 1 was released on March 11th, 2014. The primary drivers for this release were lots of bug fixes and support for VSAN. At the risk of duplicating a huge amount of the release notes, please review in detail those things that are important to you. There’s a number of things in Upgrade and Installation and there’s a specific Security section that would be of interest. Also review the Known Issues section as there’s some interesting tidbits in there as well.

5.5 Hardening Guide Update

I will be releasing an update to the vSphere Hardening Guide to go along with 5.5 Update 1 in the next couple of weeks. I’ve been collecting updates since it was released shortly after 5.5. No MAJOR changes, just minor fixes and a couple of clarifications and at least one deletion. More on this soon. I know it’s a hot button for some folks.

If there’s something YOU think needs to be corrected, now is the time to let me know!

Get in touch as a reply to this blog or preferably an email to me. I’m mfoley at
