What your server offers The design of your server takes advantage of advancements in symmetric multiprocessing (SMP), data storage, disk-array technologies, and memory management. Your server combines: v IBM X-Architecture technology IBM X-Architecture features leverage proven innovative IBM technologies to build the most powerful, scalable, reliable Intel-processor-based servers in the world. X-Architecture features include Light Path Diagnostics, Chipkill™ memory, Predictive Failure Analysis (PFA), and the Advanced System Management processor. v Impressive performance using SMP Your server supports up to two Intel Xeon microprocessors. Your server comes with at least one microprocessor installed; if it comes with one microprocessor, you can install an additional microprocessor to enhance performance and provide SMP capability. v Large data-storage and hot-swap capabilities All models of the server support up to six 25.4 mm (1-inch) slim-high, 3.5-inch hot-swap hard disk drives in the hot-swap bays. This hot-swap feature enables you to add, remove, or replace hard disk drives without turning off the server. v Active PCI (hot-plug) adapter capabilities Your server has two hot-plug slots for peripheral component interconnect (PCI) adapters. With operating system support, you can replace failing hot-plug PCI adapters without turning off the server. You can also add PCI adapters in these slots without turning off the server, if the operating system and the adapter support the hot-add feature. v Redundant cooling and power capabilities The redundant cooling and 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. Some models of the server come with two hot-swap 560-watt power supplies. The two hot-swap power supplies provide redundant power for many server configurations. If a problem occurs with one of the power supplies, the other power supply can handle the load. The NONREDUNDANT light-emitting diode (LED) on the diagnostic LED panel is lit when a problem is detected with one of the redundant hot-swap power supplies. For models that come with one fixed 560-watt power supply, a hot-swap power-supply option containing two hot-swap 560-watt power supplies is available; you can replace the fixed power supply with the hot-swap power-supply option to provide redundancy. (See the Option Installation Guide on the IBM xSeries Documentation CD for instructions.) v Large system memory Your server supports up to 6 GB of system memory. The memory controller provides error correcting code (ECC) support for up to six industry-standard, 133 MHz/266 MHz, 2.5 V, 184-pin, double-data-rate (DDR), PC2100 registered, synchronous dynamic random-access memory (SDRAM) dual inline memory modules (DIMMs). The memory controller also provides Chipkill Memory protection if all DIMMs are of the type x4. Chipkill Memory protection is a technology that protects the server from a single chip failure on a DIMM. v System-management capabilities Your server comes with an integrated system management processor (ISMP) and support for the Remote Supervisor Adapter. The ISMP, in conjunction with the 4 IBM xSeries 235 Type 8671: User's Guide
