Reliability, availability, and serviceability (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 which require service. Table 9 describes the memory
RAS features supported on the M620.
Feature
Description
Dense configuration
optimized profile
Increased memory reliability can be a 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.
