Talking about Dell blades

Green IT is the phrase of the day and reducing the “footprint” is the social goal for many organizations. Being able to accurately measure actual power consumption is an important part of the analysis of an organization’s power usage. Power supply readings are a start, but generally not accurate for actual usage as their listed figures are static and don’t take into consideration differing workloads between identical servers.
Dell’s new M1000e chassis ships with Chassis Management Controller software that provides a real-time look at how much power is being consumed by the chassis and the individual blades within the chassis. Although the software doesn’t provide a look at the power usage for each individual module in the back of the chassis, the software does tell you how much total power is being used by the chassis’ infrastructure components which include everything in the chassis except the individual blade servers.
I remain a fan of the new Dell M1000e blades, check out this article which is talking about them and illustrates the power features, an interesting read.
