Error Correction and Parity

The server's processor provides parity protection on its internal cache memories and
error-correcting code (ECC) protection of the data. The system can detect and log to
the ILOM event log the following types of errors:
Correctable and uncorrectable memory ECC errors
■
Uncorrectable CPU internal errors
■
Advanced ECC corrects up to 4 bits in error on nibble boundaries, as long as they are
all in the same DRAM. If a DRAM fails, the DIMM continues to function.
For instructions for clearing DIMM faults, see the Oracle Integrated Lights Out Manager
(ILOM) 3.0 Supplement for Sun Fire X4170 M2 and X4270 M2 Servers (821-0489).
