Installation Manual

AMP Mode Status
The status of the AMP subsystem.
• Other/Unknown—The system does not support AMP, or the management software cannot
determine the status.
• Not Protected—The system supports AMP, but the feature is disabled.
• Protected—The system supports AMP. The feature is enabled but not engaged.
• Degraded—The system was protected, but AMP is engaged. Therefore, AMP is no longer
available.
• DIMM ECC (Error Correcting Code)—The system is protected by DIMM ECC only.
• Mirroring—The system is protected by AMP in the mirrored mode. No DIMM faults have
been detected.
• Degraded Mirroring—The system is protected by AMP in the mirrored mode. One or more
DIMM faults have been detected.
• On-line Spare—The system is protected by AMP in the hot spare mode. No DIMM faults
have been detected.
• Degraded On-line Spare—The system is protected by AMP in the hot spare mode. One or
more DIMM faults have been detected.
• RAID-XOR—The system is protected by AMP in the XOR memory mode. No DIMM faults
have been detected.
• Degraded RAID-XOR—The system is protected by AMP in the XOR memory mode. One
or more DIMM faults have been detected.
• Advanced ECC—The system is protected by AMP in the Advanced ECC mode.
• Degraded Advanced ECC—The system is protected by AMP in the Advanced ECC mode.
One or more DIMM faults have been detected.
• LockStep—The system is protected by AMP in the LockStep mode.
• Degraded LockStep—The system is protected by AMP in the LockStep mode. One or more
DIMM faults have been detected.
Configured AMP Mode
The active AMP mode. The following modes are supported:
• None/Unknown—The management software cannot determine the AMP fault tolerance, or
the system is not configured for AMP.
• On-line Spare—A single spare bank of memory is set aside at boot time. If enough ECC
errors occur, the spare memory is activated and the memory that is experiencing the errors
is disabled.
• Mirroring—The system is configured for mirrored memory protection. All memory banks
are duplicated in mirrored memory, as opposed to only one for online spare memory. If
enough ECC errors occur, the spare memory is activated and the memory that is experiencing
the errors is disabled.
• RAID-XOR—The system is configured for AMP with the XOR engine.
• Advanced ECC—The system is configured for AMP with the Advanced ECC engine.
• LockStep—The system is configured for AMP with the LockStep engine.
• Online Spare (Rank Sparing)—The system is configured for Online Spare Rank AMP.
• Online Spare (Channel Sparing)—The system is configured for Online Spare Channel
AMP.
