Notes:
  1. This machine is a 32-bit platform only. 64-bit operating systems
    are not supported.
  2. 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
    7981-2FY is 7981-2FU. See the product-specific Official IBM announcement
    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.
  3. Withdrawal dates are provided for U.S. and Canada only. Business
    Partner Inventory may be available.
  4. High-speed, two-way interleaved PC2-3200 RDIMMs. Maximum capacity
    requires replacing the standard DIMMs. Memory-mirroring, hot-spare
    memory and Chipkill functions are supported.
  5. System management functionality, interconnect network connectivity
    and console connectivity are managed through the standard management
    module. The standard integrated service processor monitors HS20 - (7981)
    system management activity, communicating with the management
    module in the BladeCenter.
  6. Dual Broadcom 5704S Gb Ethernet controllers.
  7. An integrated, SAS controller supports integrated RAID-0 and 1.
  8. Maximum internal storage capacity is based on installation of
    two 73.4GB SAS HDDs.
  9. BladeCenter storage expansion units and PCI expansion units are
    not supported on the 7981.
