Explanation

ProLiant Gen9 servers include these advanced memory protection features: Dynamic fail-over to a spare DIMM rank or spare rank pair behind the same memory controller. No OS involvement. You cannot enable this feature concurrently with memory mirroring. HP offers the rank sparing rather than DIMM sparing as rank sparing uses less spare memory resulting in less overhead.
