The AFCOM association, whose members include 4,500 administrators from 3,900 data centers around the world surveyed  436 data center sites last year. Some of the findings of the survey indicated that cyberterrorism is an increasing concern, mainframe deployment is on the decline, storage deployment is on the rise, and “green” technologies are definitely happening.

It was found that there is a shift in data centers away from mainframe computers and toward other types of servers.Just less than 40 percent of data centers run two or more mainframes, with 45.7 percent of such data centers planning to replace at least one of their mainframes in the next year. However 33 percent of those replacing mainframes plan to replace them with other types of servers.
