Dell OpenManage Server Administrator Version 7.3 Command Line Interface Guide

spare: Disables the memory module that has a correctable memory event and copies the failing module’s data to a spare bank.

mirror: Switches the systems to a mirrored copy of the memory if the failing module has an uncorrectable memory event. In the mirror mode, the operating system does not switch back to the original module until the system reboot.

disabled: Indicates that the system is not to use other available memory modules if uncorrectable memory events are detected.

raid5: Method of system memory configuration. This is logically similar to the RAID-5 mode used in hard drive storage systems. This memory mode provides an extra level of memory checking and error recovery at the expense of some memory capacity. The RAID mode supported is RAID level 5 striping with rotational parity.

dddc: The dddc mode enables double device data correction. This ensures data availability after hard failure of x4 DRAM.

mirror: Switches the systems to a mirrored copy of the memory if the failing module has an uncorrectable memory event. In the mirror mode, the operating system does not switch back to the original module until the system reboots.

optimizer: Enables the DRAM controllers to operate independently in 64-bit mode and provide optimized memory performance.

advanced ECC (advecc): Enables the two DRAM controllers to combine in 128-bit mode and provide optimized reliability. Memory that are not teamed by the controllers is not reported to the operating system.
