Memory configurations
To optimize server blade availability, the server blade supports the following AMP modes:
 Advanced ECC—Provides up to 4-bit error correction. This mode is the default option for this server
blade.
 Online spare memory—Provides protection against failing or degraded DIMMs. Certain memory is
reserved as spare, and automatic failover to spare memory occurs when the system detects a DIMM
that is degrading. This allows DIMMs that have a higher probability of receiving an uncorrectable
memory error (which would result in system downtime) to be removed from operation.
 Mirrored memory—Provides maximum protection against failed DIMMs. Uncorrectable errors in one
channel are corrected by the mirror channel.
