Guide on the IBM Documentation CD.
vRedundant connection
The addition of an optional network interface card (NIC) provides a failover
capability to a redundant Ethernet connection. If a problem occurs with the
primary Ethernet connection, all Ethernet traffic that is associated with the
primary connection is automatically switched to the redundant NIC. If the
applicable device drivers are installed, this switching occurs without data loss
and without user intervention.
vRedundant cooling and power capabilities
The redundant cooling of the fans in the server enables continued operation if
one of the fans fails. The server supports up to two hot-swap power supplies,
which provide redundant power for many server configurations.
vServeRAID support
The server supports ServeRAID controllers to create a redundant array of
independent disks (RAID) configurations.
vSymmetric multiprocessing (SMP)
The server supports up to four multi-core Intel Xeon microprocessors. One or
more multi-core microprocessors providesSMP capability.
Reliability, availability, and serviceability
Three important server 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.
The server has the following RAS features:
vAdvanced memory features:
– Single-bit memory error detection
– Single-bit memory error hardware correction
– Multi single-bit memory error recovery and corrections
– Uncorrectable error (UE) detection
– Full array memory mirroring (FAMM)redundancy
– Automatic failover recovery for UEs when FAMMis configured
– Automated logical removal of failed DIMMs on reboots prior to replacement
– Automatic address parity checking during writes and reads
vAutomatic BIOS recovery (ABR) for UEFI
vAutomatic error retry and recovery
vAutomatic restart after a power failure
vAvailabilityof microcode and diagnostic levels
vIntegrated management module (service processor)
vBuilt-in, menu-driven electrically erasable programmable ROM (EEPROM) based
setup, system configuration, and diagnostic programs
vBuilt-in monitoring for fan, power, temperature,voltage, and power-supply
redundancy
vError codes and messages
vError correcting code (ECC) L2 cache and system memory
vFault-resistant startup
vHot-swap hard disk drives
