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 8843-01Y is 8843-01U. 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.
  2. Withdrawal dates are provided for U.S. and Canada only.
    Business Partner Inventory may be available.
  3. AMD Dual-Core Opteron processor with two 1MB L2 Cache, provides
    three high-performance HyperTransport links to I/O, as well as a
    128-bit high-performance DDR-2 SDRAM memory controller.
  4. Memory subsystem is two-way interleaved, Very Low Profile
    (VLP) DDR-2 SDRAMMs supporting chip kill technology. Each Opteron
    processor contains the memory controller responsible for four DIMMs.
  5. Integrated Service Processor subsystem supports Vulture 3
    features which include monitoring the LS21 systems management
    activity as well as communicating with the management module in
    the BladeCenter.
  6. Dual Broadcom BCM5706S Gigabit Ethernet Controllers
  7. An integrated LSI 1064 SAS Controller supporting one onboard
    SAS Hard Disk Drive
  8. Maximum internal storage capacity is
    based on installation of one 146GB SAS HDD.
  9. An optional BladeCenter expansion unit is available that
    attaches directly to the blade server adding three hot-swap
    SAS HDD bays for a total of four HDD bays and two expansion
    card slots for a total of three expansion card slots.
