v Redundant cooling and power capabilities The server supports up to eight hot-swap fans. Eight fans provide redundant cooling. The hot-swap capabilities of the fans in your server enable continued operation if one of the fans fails. You can also replace a failing fan without turning off the server. The server supports up to two 514-watt power supplies, which ensure redundancy and hot-swap capability for a typical configuration. v ServeRAID™ support Your server supports ServeRAID adapters to create redundant array of independent disks (RAID) configurations. v Symmetric multiprocessing (SMP) Your server supports up to two Intel Xeon microprocessors. If the server comes with only one microprocessor, you can install an additional microprocessor to enhance performance and provide SMP capability. v Systems-management capabilities Your server comes with features that a network administrator or file server can use to remotely manage and control the server. Some of the features include Wake on LAN®, IBM Director, Remote Administration, and System Migration Assistant. See the information provided with your system-management software for more information. If your server is connected to an Advanced System Management (ASM) interconnect network that is managed by a Remote Supervisor Adapter, you can view the system health; turn on, turn off, and restart the server; view the error log; view the vital product data; and send alerts over the ASM interconnect network. To obtain an optional Remote Supervisor Adapter, contact your IBM reseller or IBM marketing representative. Reliability, availability, and serviceability Three important computer design features are reliability, availability, and serviceability (RAS). The RAS features help to ensure the integrity of the data that is stored in your server, the availability of the computer when you need it, and the ease with which you can diagnose and repair problems. Your server has the following RAS features: v Automatic error retry and recovery v Automatic restart after a power failure v Backup basic input/output system (BIOS) switching under the control of the service processor v Built-in monitoring for fan, power, temperature, voltage, and power-supply redundancy v Cable-presence detection on most connectors v Chipkill memory protection v Error codes and messages v Error correcting code (ECC) L2 cache and system memory v Hot-swap hard disk drives v Information and Light Path Diagnostics LED panels v Integrated service processor subsystem for remote system management v Memory scrubbing and Predictive Failure Analysis® (PFA) (background and real time) v Menu-driven setup, system configuration, and redundant array of independent disks (RAID) configuration programs v Availability of microcode and diagnostic levels 6 IBM xSeries 345 Type 8670: User's Guide
