First up is a piece about what does and what doesn’t work with a green IT strategy. The thing that stood out in this for me was:
“Data center audits inevitably turn up servers with no connections to network cables that remain turned on.”
Anyone who disconnects a server from the data center network and leaves it powered up needs a good swat to the back of the head.
The next piece up is a post from James Hamilton about PUE. As much as I’ve talked here about the flaws in PUE, it’s certainly of some use as an internal metric. The big problem with PUE is trying to compare different data centers based on it, as well as giving out official superiority awards based on it (Energy Star for data centers). It’s probably the most misused metric ever invented.
From the “bozo is contagious” file, we have the recent Bluehost data center outage in Provo, UT. Kudos to Bluehost for actually having a power backup system that worked, squeaky red noses to the local telecom carrier for not only losing Bluehost’s Internet connections but phone service to the whole city as well.
