Server features
The unique design of the server takes advantage of advancements in symmetric
multiprocessing (SMP), data storage, and memory protection. The server combines:
• Impressive performance using an innovative approach to SMP
The server supports up to four Pentium III Xeon microprocessors. The server
comes with one microprocessor installed; you can install additional
microprocessors to enhance performance and provide SMP capability.
• Integrated disk-array subsystem (optional)
Although many operating systems provide software fault tolerance through
mirroring, IBM provides hardware fault tolerance through the redundant array of
independent disks (RAID) controller. The IBM ServeRAID™ controller is a
standard feature. It provides three channels and supports RAID levels 0, 1, 1E, 5,
and 5E.
• Large data-storage and hot-swap capabilities
All models of the server support up to 10 slim-high disk drives. The hot-swap
feature enables you to remove and replace hard disk drives without turning off
the server.
• Hot-plug PCI adapter capabilities
The server has four hot-plug slots for PCI adapters. With operating system
support, you can replace failing hot-plug PCI adapters without turning off the
server. If the hot-add feature is supported by the operating system and the PCI
adapter, you can also add PCI adapters in these slots without turning off the
server.
• Redundant cooling and power capabilities
The redundant cooling and hot-swap capabilities of the fans in the server enable
continued operation if one of the fans fails, because you can replace a failing fan
without turning off the server.
The server comes standard with three 250-watt power supplies, which support
redundancy for a typical configuration. You can install one additional power
supply.
• Large system memory
The memory bus in the server supports up to 16 GB of system memory. The
memory controller provides error correcting code (ECC) support for up to 16
industry-standard, 3.3 V, 168-pin, 8-byte, registered, dual inline memory modules
(DIMMs). The memory controller also provides Chipkill™ memory protection.
Chipkill memory protection is a technology that protects the system from
component failure on a DIMM.
• System-management capabilities
The server comes with a Advanced System Management Processor. This
processor enables you to manage the functions of the server locally and remotely.
The Advanced System Management Processor also provides system monitoring,
event recording, and dial-out alert capability.
