Memory online sparing

The chipset on the system board in your Gateway server supports memory online sparing, which can provide a way to prevent data loss in case of DIMM failure. Memory online sparing is configured in the BIOS.

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
