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. DIMMs are DDR3-SDRAM registered, required in pairs. Memory Cards support 8 DIMMs each.
  2. For pre-configured models (i.e. GAVs/SEOs) , a minimum of 1 Memory card and 2 DIMMs are REQUIRED for EACH installed CPU.
  3. Maximum: Eight memory cards, each card containing four pairs of DIMMs, 64 DIMMs per node.
  4. DIMM's must be installed in pairs. Pairs must be matching IBM PN's.
  5. For memory mirroring, Card1 mirrors Card2, Card3 mirrors Card4, Card5 mirrors Card6, Card7 mirrors Card8.
  6. Mirrored configurations require pairs of memory cards. Min sets of 4, i.e., 2 memory cards with at least 2 DIMMs populated per card, per CPU.
  7. The Cost sensitive rules are for 1 Memory card per CPU.
  8. The Performance Sensitive Configuration should always be used when there are 2 Memory cards per CPU - unless mirrored.
  9. When using the Performance sensitive rules, you must skip the table entries when the associated CPU is not installed.
