Which brings me around to an article I just read about keeping IT simple. So many organizations keep accumulating box after box after box, each of which does a simple little thing. Oftentimes, the infrastructure never gets reevaluated and then you are stuck supporting this stuff. Branton mentions that:
Capacity utilisation — or the lack of it — is one of the biggest issues with server sprawl. Analyst firm Gartner estimates that on average the capacity utilisation of servers in a typical company is no more than 20%. The remaining 80% is largely wasted. For a company that has 100 servers, that is a huge waste of computing resources, considering the costs of maintaining these servers are not cheap.Those figures comport with my experience - five times as much iron as you need. Here's some advice - have a IT garage sale every two years. Repack and consolidate. You'll be glad that you not tripping over this stuff when you are finished.
