Been a bit slow on the posing, I had to buy a new lab server SuperMicro sys-5028d-tn4t (I will post about it at a later date…) this is due to my other 3 i7 ESX hosts being in transit from Australia as I had to move back to Switzerland for personal reasons.

Some free vRops online classes below.

I recently attended an advanced troubleshooting session for the vRops application by VMware Education Services if you are interested in watching it click here and below you will find some useful screens from the presentation before you invest 50 minutes watching it.
