vSphere 5.5 Update 2 Released
VMware vCenter Server and ESXi 5.5 Update 2 has just been released with a number of fixes and additional features such as vCenter Server database support for Oracle 12c, Microsoft SQL Server 2012 Service Pack 1, and Microsoft SQL Server 2014 in vCenter Server and support for ESXi hosts with 6TB of RAM in the ESXi 5.5 update 2 release! For the full list, check here.
One particular change was a bit buried in the release notes and was not mentioned in the blog post, which tries to say it’s not a major change. However, for VMware administrators, this might be the most important change in Update 2 and the reason they will upgrade; In Update 2, you will be able to edit virtual machines with hardware version 10 again!
