BladeCenter LS22 (7901)


Attention
Attention:
A four-digit feature code is used to specify a component that is configurable in the IBM configurators, the eBusiness Configurator (eConfig) and the IBM Web-based Hardware Configurator, used in US and Canada. Options that do not have feature codes cannot be integrated by IBM into a system using these IBM configurators. To purchase options separately, refer to the option part number provided in this document.

Notes:
  1. Model numbers provided are worldwide generally available
    variant (GAV) model numbers which are not orderable as
    listed and need to be modified by country. The U.S. GAV
    model numbers use the following nomenclature: xxU.
    For example, the U.S. orderable part number for 7901-3QY
    is 7901-3QU. See the product-specific Official IBM announce-
    ment letter for other country-specific GAV model numbers.
    GAV to MTM mapping for A.P. Geographies follow the same
    pattern. Substitute the last character with a country-specific
    designator.
  2. The AMD Opteron processor is designed for high-performance
    and server applications. It provides three high-performance
    HyperTransport links to the I/O as well as a 128-bit high-
    performance DDR-2 SDRAM memory controller. Each AMD
    Quad-Core Opteron processor contains four CPUs, memory
    controller, and coherent HyperTransport interface between
    the processors as well as a non-coherent HyperTransport
    interface to the other bridge chips.
  3. The voltage regulation for the AMD Opteron processor is
    set up in a "Split Plane" configuration where a three-phase
    voltage regulator is responsible for the processor cores and
    a single-phase voltage regulator is responsible for the north
    bridge. The LS22 includes two 1207-pin LGA sockets for dual
    processor operation with integrated memory controllers.
  4. Express model.
