System Features
007-4857-002 75
• Power-on and boot:
– Automatic testing occurs after you power on the system. (These power-on self-tests or
POSTs are also referred to as power-on diagnostics or PODs).
– Processors and memory are automatically de-allocated when a self-test failure occurs.
– Boot times are minimized.
• Further RAS features:
– Optional RAID 1 in base I/O (IA2 blade), check with your SGI sales or service
representative for availability. Note that RAID 0 (striping), while supported by the IA2
hardware, is not recommended as a RAS option.
– Systems have a local field-replaceable unit (FRU) analyzer.
– All system faults are logged in files.
– Memory can be scrubbed using error checking code (ECC) when a single-bit error
occurs.
