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. Maximum Memory possible: Single rank RDIMMs 36GB (18 x 2GB); Dual rank RDIMMs 288GB (18 x 16GB) Quad rank RDIMMs 192GB (12 x 16GB)
  2. When mirroring is selected, only half of the installed memory is available to the OS. Maximum addressable memory is reduced to half of total installed DIMMs.
