Before upgrading my Virtual Center 2.5 server to vCenter Server 4.0, I decided to temporarily disable HA and DRS. This is just a precaution taken to avoid waiting for cluster reconfigurations right after the upgrade. Because I hate doing things more than once by hand, I used PowerCLI for this.

I ran into an issue with a vCenter database recently, where I couldn’t see historical performance data anymore in the past week-, month- and year-view.

$password = “rootPassword”

#Connect to [...]

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.

When taking the VMware vCenter Data Recovery lab on VMworld Europe 2009 I was totally surprised about this new product. The product, which will be part of the new vSphere line of products, is a complete disk based backup and restore solution. In my opinion it’s mainly aimed at SMB organizations however.
The product is build [...]

How could that happen?
