Online Sparing Configuration Guidelines
Online spare memory provides protection against degraded DIMMs by reducing the likelihood of uncorrected memory errors. This
protection is available without any operating system support.
Online spare memory protection dedicates one rank of each memory channel for use as spare memory. The remaining ranks are
available for OS and application use. If correctable memory errors occur at a rate higher than a specific threshold on any of the non-
spare ranks, the server automatically copies the memory contents of the degraded rank to the online spare rank. The server then
deactivates the failing rank and automatically switches over to the online spare rank.
For Online Spare memory mode configurations, observe the following guidelines:
Observe the general DIMM slot population guidelines.
Each channel must have a valid online spare configuration.
Each channel can have a different valid online spare configuration.
Each populated channel must have a spare rank.
A single dual-rank DIMM is not a valid configuration.
LRDIMMs are treated as dual-rank DIMMs.
HP Memory
NOTE:
HP memory from previous generation servers are not qualified or warranted with
this HP ProLiant Server. HP SmartMemory is required to realize the memory
performance improvements and enhanced functionality listed in this document for
Gen8. For additional information, please see the HP SmartMemory QuickSpecs at:
http://h18000.www1.hp.com/products/quickspecs/14225_na/14225_na.html
NOTE:
LRDIMM, RDIMM, UDIMM, and HDIMMs are all distinct memory technologies and
cannot be mixed within a server. The majority of ProLiant Gen8 servers support
LRDIMM, RDIMM and UDIMMs.
