Memory configurations
To optimize server availability, the server supports the following AMP modes:
• Advanced ECC—Provides up to 4-bit error correction and enhanced performance over Lockstep mode.
This mode is the default option for this server.
• Lockstep—Provides enhanced protection over Advanced ECC mode while continuing to make all
installed memory available to the operating system. The server can continue to function if a single- or
multi-bit memory failure within a single DRAM device occurs.
• 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 feature enables DIMMs that have a higher probability of receiving an uncorrectable
memory error (which results in system downtime) to be removed from operation.
Advanced Memory Protection options are configured in RBSU. If the requested AMP mode is not supported
by the installed DIMM configuration, the server boots in Advanced ECC mode. For more information, see
"HP ROM-Based Setup Utility (on page 76)."
The server also can operate in Independent Channel Mode or Combined Channel Mode (Lockstep). Lockstep
provides enhanced protection over Advanced ECC mode while continuing to make all installed memory
available to the operating system. The server can continue to function if a single-bit or multi-bit memory failure
within a single DRAM device occurs.
