v Integrated network supportThe server comes with two integrated Broadcom Gigabit Ethernet controllers,which support connection to a 10 Mbps, 100 Mbps, or 1 Gbps network. For moreinformation, see “Configuring the Gigabit Ethernet controllers” on page 81.v Large system-memory capacityThe memory bus in the server is enabled for up to 48 GB of system memory.The memory controller supports error-correcting code (ECC) for up to 12industry-standard PC2-5300, 1.8 V, 184-pin, 8-byte, registered, double-data-rate2 (DDR2) synchronous dynamic random-access memory (SDRAM) dual inlinememory modules (DIMMs). The server supports 512 MB (type x8) DIMMs andthe following sizes of type x4 DIMMs: 1 GB, 2 GB, and 4 GB.The memory controller also provides Chipkill memory protection if all DIMMs areof the type x4. Chipkill memory protection is a technology that protects thesystem from a single chip failure on a DIMM.Note: Chipkill memory protection is not supported on 512 MB DIMMs.In addition, the memory controller contains built-in technology that improvesmemory-to-microprocessor processing performance.v Online-spare memoryOnline-spare memory disables a failed pair of DIMMs from the systemconfiguration and activates an online-spare DIMM pair to replace the failed pair.v Symmetric multiprocessing (SMP)The server supports up to two AMD Opteron 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 features that a network administrator or file server canuse to remotely manage and control the server.Reliability, availability, and serviceabilityThree important server design features are reliability, availability, and serviceability(RAS). The RAS features help to ensure the integrity of the data that is stored inthe server, the availability of the server when you need it, and the ease with whichyou can diagnose and correct problems.The server has the following RAS features:v Advanced Configuration and Power Interface (ACPI)v Automatic restart after a power failurev Basic input/output system (BIOS) code boot-block recoveryv Chipkill memory protectionv Cooling fans with speed controlv Customer support center 24 hours per day, 7 days a week 2v Cyclic redundancy check (CRC)v Diagnostic CDv Diagnostic LEDs on the system boardv Diagnostic support of Ethernet adapters2. Service availability will vary by country. Response time will vary depending on the number and nature of incoming calls.Chapter 1. The System x3455 Types 7984 and 7986 server 5
