Memory RAS features
RAS features help keep the system online and operational without significant impact to performance,
and can decrease data loss and crashing due to errors. RAS aids in rapid, accurate diagnosis of faults
that require service. Table 11 describes the RAS features supported on the T320.
Table 11. Memory RAS features
Dense configuration
optimized profile
Increased memory reliability can result from this selectable platform profile that
adjusts parameters to reduce faults regarding refresh rates, speed, temperature
and voltage.
Memory demand and
patrol scrubbing
Demand scrubbing is the ability to write corrected data back to the memory once
a correctable error is detected on a read transaction.
Patrol scrubbing proactively searches the system memory, repairing correctable
errors.
Recovery from single
DRAM device failure
Recovery from Single DRAM Device Failure (SDDC) provides error checking and
correction that protects against any single memory chip failure as well as multi-bit
errors from any portion of a single memory chip.
This feature provides the ability to identify a specific failing DIMM channel pair,
thereby enabling the user to replace only the failed DIMM pair.
Memory mirroring:
intra-socket
Memory mirroring is a method of keeping a duplicate (secondary or mirrored)
copy of the contents of memory as a redundant backup for use if the primary
memory fails. The mirrored copy of the memory is stored in memory of the same
processor socket.
Memory address parity
protection
This feature provides the ability to detect transient errors on the address lines of
the DDR channel.
Memory sparing allocates one rank per channel as a spare. If excessive correctable
