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
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
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:
–
–
–Multi
–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)

vError codes and messages
vError correcting code (ECC) L2 cache and system memory
