2 IBM BladeCenter PS703 and PS704 Technical Overview and Introduction1.1 Overview of PS703 and PS704 blade serversFigure 1-1 shows the IBM BladeCenter PS703 and PS704 blade servers.Figure 1-1 The IBM BladeCenter PS703 (right) and BladeCenter PS704 (left)The PS703 blade serverThe IBM BladeCenter PS703 (7891-73X) is a single-wide blade server with two eight-corePOWER7 processors with a total of 16 cores. The processors are 64-bit 8-core 2.4 GHzprocessors with 256 KB L2 cache per core and 4 MB L3 cache per core.The PS703 blade server has 16 DDR3 memory DIMM slots. The industry standard VLPDDR3 memory DIMMs are either 4 GB or 8 GB or 16 GB running at 1066 MHz. The minimummemory required for a PS703 blade server is 16 GB. The maximum memory that can besupported is 256 GB (16 x 16 GB DIMMs).The PS703 blade server supports optional Active Memory™ Expansion, which is a POWER7technology that allows the effective maximum memory capacity to be much larger than thetrue physical memory. Innovative compression/decompression of memory content usingprocessor cycles can allow memory expansion up to 100%. This can allow an AIX 6.1 or laterpartition to do significantly more work with the same physical amount of memory, or a serverto run more partitions and do more work with the same physical amount of memory.The PS703 blade server has two onboard 1 Gb integrated Ethernet ports that are connectedto the BladeCenter chassis fabric (midplane). The PS703 also has an integrated SAScontroller that supports local (on-board) storage, integrated USB controller and Serial overLAN console access through the service processor, and the BladeCenter AdvanceManagement Module.The PS703 has one on-board disk drive bay. The on-board storage can be one 2.5-inch SASHDD or two 1.8-inch SATA SSD drives (with the addition of an SSD interposer tray). The
