A while ago I received a request from the storage department to move a whole ESX cluster to another storage I/O-Group. This would be a disruptive action.
I was wondering if storage VMotion would help me out here if they assigned me some new storage on the other I/O-Group instead of moving the current LUNs.

Today VMware just released this KB article on password aging in the ESX console. This way you can force a password change after an [...]

Because we have over [...]

When I was reshuffling some VMs from one cluster to the other, I had a VM that was cut off from the network. When I did some investigation I found that the network adapter was disconnected in the VM Settings. Hmmmm strange.
How could that happen?

Last Friday I was brainstorming with Gabrie van Zanten about the optimal placement of the VMDKs across our LUNs. We tried to come up with an algorithm that could give us insight in what would be our optimal storage layout.
First read the complete post here.
This weekend I was continuously thinking about this challenge.
I came up [...]

Ivo Beerens posted this article last week on the defunct cimservera processes that render an ESX Host unmanageable.
See also this VMWare KB Article.
Symptoms include:
Unable to log in through SSH to the ESX host.
Unable to log in on the local service console.
HA errors.
I ran into this problem a while ago too.
The reason why you cannot login [...]
