ServerB
of checking the integrity of data in DRAM. ECC provides more elaborate error
detection than parity; ECC can detect multiple-bit errors and can locate and
correct single-bit errors.
ECC Error Log
This setting logs the ECC error.
Chipkill
Chipkill is a new Advanced ECC (Error Correction Code) memory technology
that protects servers from system downtime caused by memory failures.
ECC Scrub Redirection
This setting enables/disables ECC Scrubber to correct errors detected in
DRAM during normal CPU requests (foreground scrubbing).
DRAM ECC Scrub Control
The DRAM ECC Scrub option controls the frequency at which memory read
options are corrected while the system is in an idle state.
DCache ECC Scrub Control
The Data Cache ECC Scrub option controls the time allotted for the L1 memory
cache to be corrected when in an idle state.
L2 ECC Scrub Control
The L2 ECC Scrub option controls the time allotted for the L2 memory cache
to be corrected when in an idle state.
Online Spare
Online Spare Memory mode provides a higher level of memory protection
than Standard Memory mode. It protects against single-bit errors and is
beneficial to businesses with sites that do not have sufficient IT staff avail-
able to service a failure, do not always have replacement memory on hand,
or where the server cannot be brought down before a scheduled shutdown.
