PureSystems, Bigger (and more Powerful) than a Bread Box

with 2 comments

IBM PureSystems combine the flexibility of a general purpose system, the elasticity of cloud and the simplicity of an appliance tuned to the workload.

Recently I’ve been hearing something that I find odd — Because of the simplicity, flexibility, and integrated design of PureSystems, I’ve heard the “blade” word mentioned. I mean nodes or IT Elements(ITEs) are involved here. Does this mean that the form factor appearance equates in any way to performance? How big exactly is one of these things? And I don’t mean floor space.

Using the Power Systems Performance Report, for instance, let’s take a look at the rPerf numbers.

As we know, rPerf is an estimate of commercial processing performance relative to other IBM UNIX systems. It is derived from an IBM analytical model which uses characteristics from IBM internal workloads, TPC and SPEC benchmarks. The model simulates some of the system operations such as CPU, cache and memory.

An IBM PureSystems 32-core p460 at 3.55 GHz is 331.1. What’s your guess on what that system can be compared with? The answer is: a Power 750 at 331.06. What about a 16-core p260? The rPerf is 176.6 compared with 176.57 for a 16-core Power 750. No small potatoes.

The point here is that these systems do have the advantages of blades and appliances. They have superb systems management capabilities. But also a whole lot more — including powerful performance.

It may look a little like an appliance. It may smell somewhat like a blade. It may taste like bread. But it’s also amazing in the ability to leap tall buildings in a single bound.
