v Online-spare memoryOnline-spare memory disables a failed rank pair of DIMMs from the systemconfiguration and activates an online-spare rank pair of DIMMs to replace thefailed rank pair of DIMMs. For an online-spare pair of DIMMs to be activated, youmust enable this feature and have installed an additional pair of DIMMs of thesame speed, type, size (or larger), and technology as the failed pair of DIMMs.v PCI-X adapter capabilitiesThe server has two slots for PCI-X 64-bit adapters.v PCI Express x4 adapter capabilitiesThe server has one slot for PCI Express x4 adapters. These slots accept x8adapters, but the adapters will operate as x4 adapters.v PCI Express x8 adapter capabilitiesThe server has two slots for PCI Express x8 adapters.v Redundant cooling and power capabilitiesThe server supports up to two 835-watt hot-swap power supplies. If the servercomes with only one power supply, you can install an additional power supplywith three redundant hot-swap cooling fans to add redundant power and coolingcapabilities. If the maximum load on the server is less than 835 watts and aproblem occurs with one of the power supplies, the other power supply can meetthe power requirements. The redundant cooling of the fans enables continuedoperation if one of the fans fails.v ServeRAID ™ supportThe server supports ServeRAID adapters to create redundant array ofindependent disks (RAID) configurations.v Symmetric multiprocessing (SMP)The server supports up to two Intel Xeon dual-core microprocessors. If the servercomes with only one microprocessor, you can install an additional microprocessorto enhance performance and provide SMP capability.v Systems-management capabilitiesThe server comes with a Remote Supervisor Adapter II SlimLine, which providesservice-processor functions in addition to those that the baseboard managementcontroller provides.
