    General description Chapter 1. The IBM Power 710 (8231-E1C) and IBM Power 730 servers (8231-E2C) utilize the latest POWER7 processor technology designed to deliver unprecedented performance, scalability, reliability, and manageability for demanding commercial workloads. The high data transfer rates offered by the Peripheral Component Interconnect Express (PCI Express) Gen2 slots can allow higher I/O performance or consolidation of the I/O demands on to fewer adapters running at higher rates.

    Figure 1-3 Rear view of a Power 730 system 1.4 System features The system chassis contains one processor module (Power 710) or two processor modules (Power 730). Each POWER7 processor module has either 4 cores, 6 cores, or 8 cores. Each of the POWER7 processors in the server has a 64-bit architecture, up to 2 MB of L2 cache (256 KB per core), and up to 32 MB of L3 cache (4 MB per core).

  • Page 20: Power 730 System Features

    1.4.3 Minimum features Each system has a minimum feature-set in order to be valid. The minimum Power 710 initial order must include a processor module, processor activations, memory, one HDD/SSD, a storage backplane, a power supply and power cord, an operating system indicator, a chassis indicator, and a Language Group Specify.

  • Page 21: Power Supply Features

    The Power 730 supports two processor modules. Both processor modules in the system must be identical. The number of installed cores in a Power 710 or Power 730 must be equal to the number of ordered activation codes’ features.

    1.8 IBM Editions IBM Editions are available only as an initial order. If you order a Power 710 or Power 730 Express server IBM Edition as defined next, you can qualify for half the initial configuration's processor core activations at no additional charge.

  • Page 28: Server And Virtualization Management

    In general, multiple IBM POWER6 and POWER7 processor-based servers can be supported by a single HMC. Remember: If you do not use an HMC or IVM, the Power 710 and Power 730 runs in full system partition mode. That means that a single partition owns all the server resources, and only one operating system can be installed.
