Chapter 4: Installing Components Memory online sparing The chipset on the system board in the server supports memory online sparing, which can provide a way to prevent data loss in case of DIMM failure. If a DIMM failure does occur, a DIMM fault LED adjacent to the DIMM slot will light orange to indicate the failed memory module. Using memory online sparing, one DIMM per channel (selectable in the BIOS setup utility) is used as a memory spare (the spare DIMM must be equal to, or larger than, the largest DIMM in that channel). If a DIMM begins to fail, the contents of the failing DIMM is copied to the spare DIMM in that channel. When all of the data is copied, the primary DIMM is automatically removed from service. Since one DIMM per channel is always maintained as a spare, only 75% of the installed memory is usable. Memory online sparing is configured in the BIOS. 68 www.gateway.com

Memory online sparing

The chipset on the system board in the server supports memory online sparing, which

can provide a way to prevent data loss in case of DIMM failure. If a DIMM failure does

occur, a DIMM fault LED adjacent to the DIMM slot will light orange to indicate the failed

memory module.

Using memory online sparing, one DIMM per channel (selectable in the BIOS setup utility)

is used as a memory spare (the spare DIMM must be equal to, or larger than, the largest

DIMM in that channel). If a DIMM begins to fail, the contents of the failing DIMM is

copied to the spare DIMM in that channel. When all of the data is copied, the primary

DIMM is automatically removed from service. Since one DIMM per channel is always

maintained as a spare, only 75% of the installed memory is usable. Memory online sparing

is configured in the BIOS.
