is planning to release a new class of x86 servers that treat memory, processors and solid-state disk as interchangeable components, saying a more flexible server is needed to satisfy the requirements of virtualized data centers.

IBM's new eX5 server line, based on Intel's upcoming Nehalem-EX chips, is an early example of what Gartner calls "fabric-based" computing, which allows customers to scale up memory and other resources without necessarily having to buy a new server. IBM says its goal is to move beyond today's industry-standard servers to offer something more scalable and tuned to fit demanding workloads.
Today, "if a user needs more memory and only more memory, the user has to buy a whole new server," says Tom Bradicich, IBM fellow and vice president of systems technology.
For three decades, x86 servers have been based on a desktop PC architecture that locks memory and processors together, and that model is becoming outdated and contributing to sprawl and the underutilization of individual servers, Bradicich says.
"Fundamentally, we don't think it's a good strategy to allow the base architecture of the desktop PC masquerade as an enterprise server," he says.
