Fewer Is Better IBM is pitching the X440 as an ideal solution for system managers seeking to consolidate servers within their data centers. By utilizing partitioning technologies once only found in much larger and more expensive systems, IBM said, customers can use a single server in place of dozens they previously needed.
"We have seen a dramatic uptake by customers looking to do server consolidation," said Jim Gargan, vice president and business line executive for IBMs xSeries Intel servers. "The days when a customer would have 400 servers strewn throughout their environment are really rapidly going away."
On the X440, for example, a user could divide a 16-way box into four physical servers, or 64 virtual partitions, Gargan said, with each partition using its own operating system. Although the 64 virtual partitions may seem inefficient, since various partitions are sharing the same processors, Gargan said such a configuration is well-suited to handling most business workloads. "If you have a lot of servers, chances are that at any given time some of those servers are not being utilized to their fullest capacity," he said. "So what youre able to do is to consolidate onto dramatically fewer servers because with this system you can get better performance out of each of your processors, due in large part to the additional leverage you gain through the use of high-end mainframe technology." Another feature drawn from IBMs high-end systems, in particular the pSeries line, is remote I/O, which allows users to add a dozen PCI/PCI-X adapter slots outside the server. "In addition, were also introducing a technology called the Scalability Port, which allows users to connect together four servers with a very high-speed connection," Gargan said.
