The significant cost of hosting your servers is the power. Take a computing on demand solution, one where I call HP and say I need 500 blades to operate in a calculation farm type setting. I need no EMC/SAN, just the blades and say three rackmount servers for controlling/managing them. If you ask for the break down costs of the solution, the most expensive parts form the power, the cooling and the datacenter space. The datacenter space costs we can fix, choose a remote location, somewhere outside London or a major city with reasonable communication links, reasonable transport locations, the power and the cooling we can’t do much about. Yes we can choose IBM’s bladecenter which is meant to use less power than the HP equivalent, but that only saves me so much, what we need is more efficient data center design, more efficient application coding coupled with vmware where appropriate.
In the example above, you need three physical boxes (using traditional thinking) I need an altiris/build server, a DNS box, maybe a SMS box or another management server like a rendezvous market feed server.
How about I have one DL585 (or equivalent), or even a few blades running ESX which then provide this functionality? One physical box hosting the management infrastructure? From the business case iinfrastructure is a fixed cost, it’s a loss, a cost of doing business, why not make it virtual, less space/power intensive?
