VMWare and Snapshots

Posted by: Raj Perumal

This is one of those things you learn the hard way. The ability to snapshot a VM in VMWare is a great feature, but unfortunately if left unattended could grow to be a bit of an issue. Snapshots are great if you need to make changes and need to quickly undo them.

However once you take a...

With it being summer, it's got me thinking about heat on a daily basis. Especially server room heat. I've been through my fair share of server rooms and I've seen all sorts of solutions to the ever increasing heat problem. It seems more and more applications require a specific server to run;...

One of the most overlooked items during a server implementation is power planning. I have seen many administrators get excited about ordering their new servers or other network equipment, plan the outage for the day of the install and then once they have all their equipment realize that they...

Hi folks, today I'd like to talk about BES installations. I find that BES is one of those server installations that lends itself well to virtualization. You see I like to run BES on it's own server so if you need to reboot it or perform any maintenance, it won't affect other services.

There is one commonality here in Winnipeg, Manitoba. Lots of servers, using a lot of power. Being a province that generates our own Hydro, we have pretty cheap electricity without having to worry about the expense of power like other provinces or states do. However this doesn't mean we shouldn't...

Tuning VMWare

One of the most common mistakes I see when out in the field with VMWare, is incorrectly configured VMWare ESX servers. It is very common to see people configure virtual machines as if they are physical machines. If you are going to implement VMWare in your environment I highly suggest going...
