Altos G530 supports memory sparing function. To provide a more fault tolerant system, Altos G530 includes special hardware to support fail- over to a spare DIMM device in the event that a primary DIMM in use exceeds a specified threshold of runtime errors. One of the DIMMs installed per channel will not be used, but kept in reserve. In the event of significant failures in a particular DIMM, it and its corresponding partner in the other channel (if applicable), will, over time, have its data copied over to the spare DIMM held in reserve. When all the data has been copied, the reserved DIMM will be put into service and the failed DIMM will be removed from service. Only one sparing cycle is supported. If the memory sparing feature is not enabled, then all DIMMs will be visible in normal address space.
Refer to “Memory Configuration” on page 101 for more information about configuring the memory spare parameter in the BIOS Setup Utility.
