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
