Reliability Feature Benefit

• Data is written to two locations in system memory so that if a

DRAM device fails, mirrored memory enables continued operation

and data availability

Memory ECC

Enhanced Memory ECC

Memory Mirroring

Memory CRC

• Detects and corrects single-bit errors

• Retry double-bit errors

• Predicts a failing DIMM and copies the data to a spare memory

DIMM, maintaining server availability and uptime

• Address and command transmissions are automatically re-tried

if a transient error occurs

Symmetric Access to All CPUs

Memory Sparing

• Enables a system to restart and operate if the primary processor fails
