Why UCS Rocks #4: Efficiency
Note: If you want to read an in-depth article on power management, check out the Cisco white paper, Power Management in the Cisco Unified Computing System: An Integrated Approach.
SPECpower_ssj2008 is the first industry-standard benchmark that evaluates the power and performance characteristics of single server and multi-node servers.
It is not possible for a single benchmark to represent the energy efficiency for all of the possible combinations of an IT environment. . . . However, it is very possible for a single benchmark to give an indication of the relationship between power and performance for the components that the benchmark stresses. — SPEC.org
And this is with only a single eight-blade chassis; imagine the saving at scale! Since the Fabric Interconnects are only needed once, the savings scale out dramatically as you add more and more servers, because each chassis incrementally consumes less. Cisco UCS's power-to-weight ratio actually gets better as it gets bigger!
Choosing Cisco UCS would save you $250 annually in power costs. Of course that seems like a little, right? But a little bit here and a little bit there adds up. And imagine it at scale, too; if you are talking about two racks of chassis with 64 blades, the power savings will be in the thousands.
