High density data centers use electricity more efficiently, but they also tend to be busier – increasing total electric consumption. Further, according to Jim Shanahan (head of ABB’s Global Data Center business) in a recently published article (see link and embed below), as density increases, so do energy costs as a percentage of operating expense.
According to Shanahan, there are the four steps – admittedly much-simplified – to achieve hyper-efficiency in converting power to data.
Step 1: Implement the one-off improvements.
Step 2: Run the data center like a profit center.
Step 3: Chase every watt.
Step 4: Virtualize
