There are also some architectural limits for current Arm-based chips that could hamper server adoption, Brookwood said. For example, memory limits of up to 4GB could limit server operations from a software standpoint.

The current and Cortex-A15 architectures are also based on 32-bit processor design, Brookwood said. While Intel and AMD moved up to 64-bit design a while ago, Arm is behind its rivals.

"The next iteration of Arm in 2011 or 2012 will come out with 64-bit extensions," Brookwood said.
