IBM's Cluster 1600 will now link together as many as 32 of its most powerful Unix servers in a configuration that the company has tuned to get the best performance out of the systems.
IBM offers 32 of its p690 servers, each with 32 processors, or 32 of its p670 servers with 16 processors, along with its cluster management software. Both of these configurations are twice the size of its previous cluster offerings for those systems, said Barbara Butler, director of Unix clusters at IBM. IBM also builds larger clusters on a custom basis.
"This is for customers looking to clustering for performance or simply for easier ways to manage lots of servers," she said.
A cluster is group of servers connected together that can be managed either as one computer or divided up to run several applications. Linking servers together in this way can help scientific researchers or car manufacturers, for example, beef up their computing power to handle large calculations.
The Cluster 1600 runs IBM's AIX version of the Unix operating system. The servers can also be split up into multiple partitions, each running either AIX or Linux, Butler said.
A Cluster 1600 with only two 32-way p690 servers and a control workstation starts at about $2.4m (£1.5m)
The p690 systems run on either 1.1GHz or 1.3 GHz Power4 processors. The p670 systems are available only with 1.1GHz chips.
