Reliability, Availability, And Serviceability - IBM System x3690 X5 Installation And User 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 Types 7147 and 7148)
v 24-hour support center
v Automatic error retry and recovery
v Automatic restart on nonmaskable 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 Double-device data correction (DDDC) for x4 DRAM technology DIMMs
v Diagnostic support for ServeRAID and Ethernet adapters
v Error codes and messages
v Error correcting code (ECC) L3 cache and system memory
v Full Array Memory Mirroring (FAMM) redundancy
v Hot-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 (IMM)
v Light path diagnostics LEDs for memory DIMMs, microprocessors, hard disk
v Menu-driven setup, system configuration, and redundant array of independent
v Microprocessor built-in self-test (BIST), internal error signal monitoring, internal
v Memory mirroring support
v Memory error correcting code and parity test
v Memory down sizing (non-mirrored memory). After a restart of the server after
v Nonmaskable interrupt (NMI) button
v Parity checking on the small computer system interface (SCSI) bus and PCI
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
and 4-year parts and 4-year labor limited warranty (Machine Types 7149 and
7192)
management module (IMM)
redundancy
(available on 16 GB DIMMs only). Ensures that data is available on a single x4
DRAM DIMM after a hard failure of up to two DRAM DIMMs. One x4 DRAM
DIMM in each rank is reserved as a space device.

voltage regulator module failure identification through light path diagnostics
the memory controller detected a non-mirrored uncorrectable error and the
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 restrats with the remaining installed memory.
