ESXi Time Configuration: Don’t point it towards the Windows Domain name

By | December 16th, 2014|ESX, vCenter, Virtual Lab, Virtualization, VMware, vSphere|2 Comments

Like all VMware techies, I have also installed shared storage in different ways, to experiment with high-availability solutions.  One thing that has always bugged me is that virtual appliances providing shared storage, need to have the virtual environment running as a prerequisite.  In a home lab, one might not have an external NAS box so [...]

Building (or Upgrading) a Virtual Home Lab Machine – Part I

By | September 30th, 2012|ESX, Virtual Lab, Virtualization, VMware, vSphere, Workstation|8 Comments

I've had my virtual infrastructure labs in their various incarnations for more than a decade now and the most recent one is based around a "whitebox" Dual-Quad core Xeon server, with 24 GB RAM.  This system was built in 2007 so the processors (while the best in their time) have become a bit of a limitation now.
