Feature

Description

Memory mirroring:

intra-socket

Memory mirroring is a method of keeping a duplicate (secondary or mirrored)

copy of the contents of memory as a redundant backup for use if the primary

memory fails. The mirrored copy of the memory is stored in memory of the same

processor socket.

Memory address parity

protection

This feature provides the ability to detect transient errors on the address lines of

the DDR channel.

Memory sparing (rank)

Memory sparing allocates one rank per channel as a spare. If excessive correctable

errors occur in a rank or channel, they are moved to the spare area while the

operating system is running to prevent the errors from causing an uncorrectable

failure.

Memory thermal

throttling

This feature helps to optimize power/performance and can also be used to

prevent DIMMs from overheating.

For information on memory mirroring and sparing configurations, see the

Dell PowerEdge R720 and

R720xd Owner’s Manual

on Dell.com/Support/Manuals. Memory RAID is not supported.
