The IBM Power 595 server is designed to help enterprises deploy the most cost-effective andflexible IT infrastructure, while achieving the best application performance and increasing thespeed of deployment of new applications and services. As the most powerful member of theIBM Power Systems family, the Power 595 server is engineered to deliver exceptionalperformance, massive scalability and energy-efficient processing for a full range of complex,mission-critical applications with the most demanding computing requirements.Equipped with ultra-high frequency IBM POWER6 processors in up to 64-core, symmetricmultiprocessing (SMP) configurations, the Power 595 server is designed to scale rapidly andseamlessly to address the changing needs of today's data centers. With advanced PowerVMvirtualization, EnergyScale technology, and Capacity on Demand (CoD) options, thePower 595 is ready to help businesses take control of their IT infrastructure and confidentlyconsolidate multiple UNIX®-based, IBM i, and Linux application workloads onto a singlesystem.

The Power 595 (9119-FHA) server consistsof the following major components:

� A 42U-tall, 24-inch system rack that houses the CEC, Bulk Power Assemblies (BPA) that are located at the top of the rack, and I/O drawers that are locatedat the bottom of the rack. A redundant power subsystem is standard.Battery backup is an optionalfeature. CEC featuresinclude:

–A 20U-tallCEC housing that featuresthe system backplane cooling fans, system electronic components, and mountingslots for up to eight processor books.

– One to eight POWER6 processorbooks. Each processorbook contains eight,

dual-threaded SMP cores that are packaged on four multi-chip modules (MCMs). Each MCM contains one dual-core POWER6 processor supportedby 4 MB of on-chipL2 cache (per core) and 32 MB of sharedL3 cache. Each processor book also provides:

•Thirty-two DDR2 memoryDIMM slots

•Support for up to four GX based I/O hub adapter cards (RIO-2 or 12x) for connection to system I/O drawers

•Two Node Controller (NC) service processors (primaryand redundant)
