IBM server goes 16-way, on demand

An expandable, partitionable 16-way Intel Xeon MP server from IBM Corp. comes in a 14-inch-high rackmount case like the company's other eServers. But the new eServer x440 has XpandOnDemand architecture, said Mike Nelson, director of Internet technologies for IBM's server group.

A data center can buy a four-way system and add four-processor modules as needed. Interconnects link the modules at speeds of up to 3.2 Gbps.

Users can divide the 16 processors into as many as four physical and 16 virtual partitions, which can run different operating systems, Nelson said.

The x440 accommodates up to 64G of memory. IBM's Chipkill memory architecture transfers data to a spare memory module if a main module fails. Microsoft Windows 2000 Datacenter Server is the standard operating system. An eight-way configuration lists for $50,808 with 1.4-GHz Intel Xeon MP processors, 16G of synchronous dynamic RAM and two 36G hard drives. A 16-way setup with the same CPUs and four 36G disks is $102,494.
