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 7944-12Y is 7944-12U. 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 the country- specific designator.
  2. LC abbreviation indicates that the US models ship standard with a line cord. Models without line cords will be indicated with a hyphen.
  3. Withdrawal dates are provided for U.S. and Canada only. Business Partner Inventory may be available.
  4. 2.5" SAS Form Factor
  5. For 7944 A2Y, B2Y, C2Y, D2Y, F2Y, G2Y, H2Y, J2Y, M2Y, N2Y, to upgrade maximum number of hard disk drive to 8, option 59Y3951 should be selected. When option 59Y3951 is selected, you cannot have an internal optical drive.
  6. For 7944 A2Y, B2Y, C2Y, D2Y, F2Y, G2Y, H2Y, J2Y, M2Y, N2Y, if optical drive is needed, option 59Y3952 should be selected.
  7. For 7944 E1Y, E2Y, E3Y, to upgrade maximum of hard disk drive to 8, option 59Y3992 should be selected
  8. Quad rank RDIMMs 192GB (12 x 16GB)
  9. If you select the 7944 E1U, E2U, E3U and try to remove the installed optical drive and add 8 HDD, you can only select the pn 59Y3992, selecting 59Y3951 which is incorrect to install 8 HDD.
