Reliability, Availability, And Serviceability - IBM System x3300 M4 Installation And Service Manual

Reliability, availability, and serviceability

Three important computer design features are reliability, availability, and
serviceability (RAS). The RAS features help to ensure the integrity of the data that
is stored in the server, the availability of the server when you need it, and the ease
with which you can diagnose and correct problems.
Your server has the following RAS features:
v 3-year parts and 3-year labor limited warranty (Machine Type 7382)
v 24-hour support center
v Automatic error retry and recovery
v Automatic restart on non-maskable interrupt (NMI)
v Automatic restart after a power failure
v Backup basic input/output system switching under the control of the integrated
v Built-in monitoring for fan, power, temperature, voltage, and power-supply
v Cable-presence detection on most connectors
v Chipkill memory protection
v Diagnostic support for ServeRAID and Ethernet adapters
v Error codes and messages
v Error correcting code (ECC) L3 cache and system memory
v Simple-swap cooling fans with speed-sensing capability
v Hot-swap hard disk drives
v Information and light path diagnostics LED panels
v Integrated Management Module II (IMM2)
v Light path diagnostics LEDs for memory DIMMs, microprocessors, hard disk
v Memory mirrored channel support (memory mirrored channel are mutually
v Memory error correcting code and parity test
v Memory down sizing (non-mirrored memory). After a restart of the server after
v Menu-driven setup, system configuration, and redundant array of independent
v Microprocessor built-in self-test (BIST), internal error signal monitoring, internal
v Parity checking on the small computer system interface (SCSI) bus and PCI-E
v Power management: Compliance with Advanced Configuration and Power
v Power-on self-test (POST)
v Predictive Failure Analysis (PFA) alerts on memory, microprocessors, SAS/SATA
v Redundant Ethernet capabilities with failover support
v Redundant hot-swap power supplies
v Redundant network interface card (NIC) support
v Remind button to temporarily turn off the system-error LED on the optional
v Remote system problem-determination support
v ROM-based diagnostics
v ROM checksums

memory controller cannot recover operationally, the IMM logs the uncorrectable
error and informs POST. POST logically maps out the memory with the
uncorrectable error, and the server restarts with the remaining installed memory.
