Server consolidation

Raj Perumal Raj Perumal Profile: Raj Perumal

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 be a little more green to help out the rest of the world.

It is quite often I will see server rooms filled with racks and racks of servers with no heed paid to virtualization at all. A lot of people believe it or not, still haven’t even heard of it as they are busy focusing on other things in their business and don’t keep their ear to the ground in the IT world. It’s at times like these that I like to point out the benefits of virtualization.

You can easily take an HP C3000 blade enclosure (this enclosure, aka the “shorty” is targeted at the SMB market) and fill it with server blades, a tape blade and a storage blade, and consolidate racks worth of servers down into 6U of space. Then you can install VMWare ESX Server on the server blades and potentially have tons of virtual machines per blade server. If you haven’t looked into these technologies lately I suggest you do, they are the next big thing in IT and have just been getting better and better.

 By doing this you can save your company money on power, thermal, physical space constraints, and sheer amount of servers and racks you have to buy. Also by implementing VMWare on a blade enclosure, you increase the level of redundancy you have greatly over what you would typically have in standard configuration of one server installation per rack mounted server by taking advantage of the features available to you in VMWare and in the blade enclosure.
