First off today is reading about SSDs (solid state drives) and where they fit into the network, servers, storage, etc. These things are “quite inexpensive”? $6900 for 320GB, $11000 for 146GB (minimum of 3 required for $33000!), or the bargain basement price of $2000 for just 64GB? Are you kidding? At less than $100 for 1TB hard drives, these things have maybe a use as strategically positioned accelerators for critical services or where cost is no issue. Otherwise, I don’t think the mechanical hard drive has much to worry about.
Next is this little piece about data center retrofit strategies. Doing something different with the data center UPS is a no-brainer, but changing the PDUs? A PDU doesn’t consume any power. Don’t change your data center PDUs expecting your electrical usage to go down from it.
