Advanced Memory Protection

This section displays the following information about the Advanced Memory Protection sub-system.

Advanced Memory Protection Mode Status displays status of the Advanced Memory Protection sub-system. The following states are supported:

  • Other - The system does not support Advanced Memory Protection or the Management Agent cannot determine the status.

  • Not Protected - The system supports Advanced Memory Protection but the feature is disabled.

  • Protected - The system supports Advanced Memory Protection. The feature is enabled but not engaged.

  • Degraded - The system was protected, but the Advanced Memory Protection has been engaged; therefore Advanced Memory Protection is no longer available.

  • dimmEcc - The system is protected via DIMM ECC only.

  • mirrorNoFaults - The system is protected by Advanced Memory Protection in the mirrored mode. No DIMM faults have been detected.

  • mirrorWithFaults - The system is protected by Advanced Memory Protection in the mirrored mode. One or more DIMM faults have been detected.

  • hotSpareNoFaults - The system is protected by Advanced Memory Protection in the hot spare mode. No DIMM faults have been detected.

  • hotSpareWithFaults - The system is protected by Advanced Memory Protection in the hot spare mode. One or more DIMM faults have been detected.

  • xorNoFaults - The system is protected by Advanced Memory Protection in the XOR memory mode. No DIMM faults have been detected.

  • xorWithFaults - The system is protected by Advanced Memory Protection in the XOR memory mode. One or more DIMM faults have been detected.

  • advancedEcc - The system is protected by Advanced Memory Protection in the Advanced ECC mode.

Available Advanced Memory Protection Mode displays the options available.

  • XOR - This system is configured for Advanced Memory Protection using the XOR engine.

  • Mirrored memory with dual memory boards - This system is configured for Mirrored Advanced Memory Protection within a dual memory board configuration. The mirrored memory may be swapped with memory on the same memory board or with memory on the second memory board.

  • Mirrored Memory within a single memory board - This system is configured for Mirrored Advanced Memory Protection within a single memory board.

  • Advanced ECC - This system is configured for the Advanced ECC type of Advanced Memory Protection

  • Mirrored (deprecated) - This system is configured for Mirrored Advanced Memory Protection

  • Online Spare - This system is configured for Online Spare Advanced Memory Protection.

Configured Advanced Memory Protection Mode displays the currently active type of Advanced Memory Protection based on the types available. The following connection states are supported:

  • Other - The Management Agent cannot determine the Advanced Memory Protection fault tolerance. You may need to upgrade your software.

  • None - This system is not configured for Advanced Memory fault tolerance.

  • Online Spare Memory - A single spare bank of memory is set-aside at boot time. If enough ECC errors occur, the spare memory will be activated and the memory experiencing the errors will be disabled.

  • Mirrored Memory - This 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 will be activated and the memory experiencing the errors will be disabled.

  • XOR - This system is configured for Advanced Memory Protection using the XOR engine.

Memory Board Summary

This section displays the following information about the Memory Board.

Board - The slot in which the memory board or cartridge is installed.

Board Status - This provides the current status of the Advanced Memory Protection memory board or cartridge.

Present - This value specifies presence of the memory board instance.

Removal Conditions describes the conditions under which a Memory Board can be removed.

Locked - The locked state of the Advanced Memory Protection board.

Total Memory - This value specifies the size of memory for this board or cartridge, including memory seen by the Operating System and the memory used for spare, mirrored, or XOR configurations.

Memory In Use By OS - This value specifies the size of memory for this board or cartridge as seen by the Operating System.

Memory Board Details

The following information about each processor in the system is available in this window. This information may vary depending on device type.

  • Socket displays the socket number for the memory module.

  • Status displays the status of the memory board.

  • Type displays the following values depending on the type of memory module selected.

    • Not installed

    • Board - (The memory module is permanently mounted (not modular) on a system board or memory expansion board.)

    • Single width module

    • Double width module

    • SIMM - (Single Inline Memory Module)

    • PCMCIA - (Personal Computer Memory Card International Association technology memory module)

    • Compaq/HP specific memory module

    • DIMM - (Dual Inline Memory Module)

  • Position in Row specifies the position of the physical memory in a row. For example, if it takes two 8-bit memory devices to form a 16-bit row, then a value of '2' means that this memory is the second device

  • Size displays the size of the memory module.

  • Data Width specifies the Data width of the physical memory, in bits.

  • Removal Condition describes the conditions under which a Memory Board can be removed.
