Features
Introduction
With a maximum of two hard disk drives and on-board RAID functionality,
enough capacity is available for installation of the operating system or applica-
tions with static content such as web server or terminal server software.
In order to use PCI (33 MHz or 66 MHz) or PCI-X low profile expander controller
cards for configurations with external hard disk drives or storage subsystems
the server blade Pentium
®
M can be expanded with LAN-PCI or FC-PCI
modules.
A fully redundant, hot-swap design of the server blade ensures that blades can
be added or exchanged without interruption of service. The compact design
allows up to 20 server blades to be installed in a chassis of only 3 HU (height
units) in a 19-inch rack.
All data traffic into and out of the Blade Server System moves via LAN connec-
tions. A common backplane in the server chassis with four redundant switch
blades provides high-speed LAN access via multiple Gigabit interfaces.
Each switch blade has ten downlink ports to the server blades and three uplink
ports to layer-3 switches. These LAN connections provide the only I/O function-
ality for the server blade.
The two management blades have separate LAN connections for maintaining
accessibility to the system even when the standard traffic network connections
are down.

Features
CPU
One or two low-voltage (LV) Intel
®
Pentium
®
III processors with 800 MHz up to
1 GHz and 512 kB second-level cache and/or Pentium
®
M processors with 1.4
GHz or 1.6 GHz and 1 MB second-level cache in up to 20 hot-swappable CPU
server blades ensure high data throughput and system performance.
Memory
There are two memory sockets available on each server blade. The server
blade Pentium
®
III can be populated with 256 MB, 512 MB or 1 GB 133 MHz-
SDRAM, the server blade Pentium
®
M with 512 MB 1 GB or 2 GB
200 MHz-DDR RAM modules. The maximum memory expansion is for 2 GB for
server blades Pentium
®
III and 4 GB for server blades Pentium
®
M.
ECC with memory scrubbing function is standard.
