That call comes from distinguished engineer Dr. Dileep Bhandarkar, of Microsoft Global Foundation Services, a core part of the team that looks after Microsoft’s data centers. So you can assume he knows what he’s talking about in their server space and that Intel will take his request seriously.
Although not suitable for all server workloads, Bhandarkar believes Atom is better suited than Xeon chips for specific tasks. He thinks the power savings would make Atom servers worth deploying for the overall cost savings they would offer. He also believes the same is true of AMD’s low-power Bobcat chips. There’s hope for ARM chips appearing in Microsoft data centers in the future too. Windows is going to get support for ARM, and Bhandarkar says ARM just needs to prove its performance worth. For the moment, Intel says it has no plans for a server version of its low power processor, but with Microsoft executives as enthusiastic as Bhandarkar putting the pressure on, it may just happen in the next few years.
