• 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.
• Intersocket Mirroring—The system is configured for mirrored intersocket AMP between
the memory of two processors or boards.
• Intrasocket Mirroring—The system is configured for mirrored intrasocket AMP between the
memory of a single processor or board.
Supported AMP Modes
• RAID-XOR—The system can be configured for AMP using the XOR engine.
• Dual Board Mirroring—The system can be configured for mirrored advanced memory
protection in a dual memory board configuration. The mirrored memory can be swapped
with memory on the same memory board or with memory on the second memory board.
• Single Board Mirroring—The system can be configured for mirrored advanced memory
