System Features
007-5832-002 45
– All high speed links including Intel Quick Path Interconnect (QPI), Intel Scalable
Memory Interconnect (SMI), and PCIe have CRC check and retry.
– The NUMAlink interconnect network is protected by cyclic redundancy check (CRC).
– Each blade/node installed has status LEDs that indicate the blade’s operational
condition; LEDs are readable at the front of the IRU.
– Systems support the optional Embedded Support Partner (ESP), a tool that monitors the
system; when a condition occurs that may cause a failure, ESP notifies the appropriate
SGI personnel.
– Systems support remote console and maintenance activities.
• 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:
– 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.
