For additional information about DSA, see the Problem Determination and Service 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 provides SMP 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 FAMM is 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

vAvailability of 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
