Memory RAID
If four memory boards with equal memory capacity are installed on the
server, the system can be configured for Memory RAID. Memory RAID
mode acts similar to RAID level 4, where data is written to three of the
memory boards and the fourth is held in reserve for memory parity
information.
When one board fails, the memory subsystem operates in non-
redundant mode. The data from the remaining three boards is used to
reconstruct the data that was on the failed memory board. When the
failed memory board location is hot-replace, the BIOS rebuilds the
RAID by reconstructing the data that was on the previously failed
memory board and writes the data to the newly installed board. When
the rebuild is complete, the system is once again in redundant mode.
The BIOS sets the memory board RAID LED to indicate that the memory
board is operating in the memory RAID mode.
