Windows and Linux Data Centers Lag Behind Unix in Realizing Economies of Scale

September, 2007


In this article, we examine total data center spending per server OS instance across data centers of varying sizes. We break down these metrics for Windows, Linux, and Unix systems. Interestingly, Unix data centers experience significantly better economies of scale than Windows or Linux shops. We report the metrics and examine the reasons for the greater efficiencies in large Unix shops compared to other operating systems. (3 pp., 1 fig.)
