After months of running the vSphere 5.1 appliance in my lab, I decided to install the 5.5 appliance to see just how far this little gem has come. So, I downloaded and deployed the OVA, and moved onto initial configuration. After the initial configuration was completed, I decided to tweak some values in the interface. First and foremost - the DHCP configuration had to go. Followed by setting the host FQDN, which was strangely omitted from the initial configuration. This made running AD authentication a little difficult since AD integration requires that the appliance have an FQDN before it will accept the configuration.
vCenter Server Heartbeat (vCSHB) is a great mechanism for protecting vCenter Server and related or supporting services, such as its Microsoft SQL database or Horizon View Composer. However, with any solution of this magnitude, there will be points in the design to which careful consideration needs to be applied.
