As everyone probably already knows by now there’s a problem with 3.5 U2.  VMware is working on a patch as we speak. There has been a KB article released, but it seems like everyone is clicking on the same link at the same moment cause it’s hard to get a decent respond. The error message that appears: This product has [...]

I’ve seen a lot misinterpretations of the new advanced HA option “das.allowNetwork”. What is this option for and when should I use it or shouldn’t is the most asked question. So let’s start with a little history, back in the days “pre 3.5 U2″ one could configure a cluster on multiple IP subnets without facing any problems, but this could [...]

Seva, a VMware Technical Account Manager, put together a cool table with the implications of a VirtualCenter crash. This is a follow up to my blog about VirtualCenter getting more important by the minute.

There has always been much discussion about the VirtualCenter database if it was important enough to back it up. Most people agreed that the information that the database held was not important. A datacenter and cluster could be easily reconfigured and all other settings were saved on the host. HA wasn’t even using VirtualCenter, and DRS well a day without [...]

How about backing up that dreadful application/server that you couldn’t or did not wanted to virtualize to your ESX environment? It could be useful to have a copy of a server that for whatever reason you did not virtualize. The new VMware Converter plugin for VirtualCenter gives you this option. You can create a reoccurring schedule for a p2v, you [...]
