Linux for the cautious

	Agencies and integrators with significant investment and expertise in Unix can experiment with Linux while protecting their Unix base by using servers built on IBM Corp.'s Power 4 family of processors. The Power4 line runs IBM's eServer pSeries, which are high-performance Unix servers.

Agencies and integrators with significant investment and expertise in Unix can experiment with Linux while protecting their Unix base by using servers built on IBM Corp.'s Power 4 family of processors. The Power4 line runs IBM's eServer pSeries, which are high-performance Unix servers.

Last month, IBM introduced Linux support in its pSeries servers. Using IBM's logical partitioning technology, IT groups can run Linux and Unix concurrently. The Power4 is a 64-bit server processor designed with two separate, symmetrical, multiprocessing chips in a single design.

IBM is making a push to get Linux into government agencies, having received EAL 3 security certification for its servers running Novell Inc.'s Suse Linux.
