Upgrades to VMware vSphere will Impact Availability and Security!

I was upgrading my nodes from VMware VI3 to VMware vSphere and used the VMware Update Manager to perform the update. Given that my existing filesystems were implemented to meet the requirements of the DISA STIG for ESX, as well as availability. I was surprised to find that when the upgrade of the first node of my cluster completed, that the install did NOT take into account my existing file system structure, but instead imposed the default file system used by the standard VMware vSphere ESX 4 installation.

Going to vSphere — The Need to Upgrade

I have been preparing my virtual environment for a VMware vSphere upgrade. Specifically I have been going over my existing hardware with an eye towards running all aspects of vSphere including VMware Fault Tolerance (FT), NPIV, Cisco Nexus 1000V, and well everything.
