I was doing an in-place upgrade of a vCenter 5.5 to vCenter 6 (Windows), when I encountered an unusual error, that didn’t seem to have a relevant KB article or much other information. This was most definitely NOT a database incompatibility, as was indicated by the second error. It turns out that the solution is

For the last 10 to 15 years, I have been in and out of Data Centers of all types. I’ve also had the privilege of working in many different capacities, from corporate IT pawn, to the guy running the project. During this time I have had the privilege of working with and learning from some

I began an upgrade of the VMware vCenter Server Appliance from 5.5 to 6 for a small (in VMware’s own terminology ‘Tiny’) vSphere environment of 3 hosts and about 30 VMs. I certainly didn’t anticipate any trouble beyond the usual hassles associated with upgrading an infrastructure-level service like vCenter.

One of the advantages of my job is: unprecedented access to vendors and resources! If there is a specific lab you would like to see, just comment on this post and I will try to get it done! I am approaching a long bit on-the-road (until January 25th!), so no promises as to how quickly

We are going to install ESXi 6 on a physical server using HP’s IPMI interface known as iLO to perform the install. iLO is considered best-in-class for IPMI consoles, but still can take some getting used to. IPMI out-of-band interfaces collectively have the advantage of allowing users to: Power servers on and off Connect to ISO

One extremely important advantage of the VMware vCenter Server Appliance (VCSA) is its native PostgreSQL (vPostgres) database. With the embedded database and VCSA, it is now possible to support installations which scale to the maximum capability of vCenter, without additional Operating System or Database licensing costs.

Integrating VMware vCenter Server with Microsoft Active Directory has always been a requirement for enterprise deployments of VMware vSphere. Before SSO, In VMware vCenter 5.0 and prior, the Windows Server (VM or physical) where vCenter was installed was required to be a member-server of an Active Directory domain. In those days all Administrators of the
