Power6 is designed to run at 4.7GHz, twice the processing speed of IBM's predecessor Power5+ chip. IBM not only aims to double the processing speed over the Power5 chip, but also .
The company plans to introduce the Power6 chip throughout two server lines--the System p machines that run Unix and the System i machines that run the i5/OS operating system. Both systems also can run Linux.
A shipping schedule and pricing for the System i with the Power6 chip are not yet available.
IBM also said it will release a feature called Power6 Live Partition Mobility later this year that will let customers move a running instance of Unix from one physical machine to another. The feature, which aids flexibility and protection against hardware failure, is currently in beta testing.
