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 technology is an IBM design blueprint that takes full
advantage of existing IBM technologies to build powerful, scalable, and reliable
Intel-processor-based servers.
v Impressive performance using an innovative approach to SMP
Your server supports up to four Intel Xeon MP microprocessors with
Hyper-Threading technology and Intel NetBurst
™
microarchitecture. Your server
comes with at least one microprocessor installed; you can install additional
microprocessors to enhance performance and provide SMP capability. You can
enable the Hyper-Threading feature through the
Advanced Setup menu of the
Configuration/Setup Utility program. See “Using the Configuration/Setup Utility
program” on page 14 for details about the Configuration/Setup Utility program.
v
Large data-storage and hot-swap capabilities
Your server supports up to six standard and six optional 26 mm (1-inch) slim-high
3.5-inch hot-swap hard disk drives in the hot-swap drive bays. This
hot-swap
feature enables you to remove and replace hard disk drives without turning off
the server.
v
Active
™
PCI and Active
™
PCI-X (hot-plug) adapter capabilities
Your server has six hot-plug slots for peripheral component interconnect (PCI)
adapters. With operating system support, you can replace failing hot-plug PCI
and PCI-X adapters without turning off the server. You can also add PCI and
PCI-X adapters in these slots without turning off the server, if your operating
system and the PCI and PCI-X adapter support the
hot-add feature.
