Why you need to check those HCL's

We ordered a server to be installed as a vmware server for lab purposes this fall. As we did this, and told the vendor what we wanted to do with the server, we were confident we'ld get a functioning server. 
Well, imagine our surprise when it turned out we could not install the VMWare softare. We ran into the problem and solution described in this post: http://www.bramschoenmakers.nl/en/node/500. It is up and running, but I'm sad to say it is true what the post say about disk preformance. So I guess I'm all ready looking for a new server.....
