xSeries 450 Planning and Installation Guide
3.1
System hardware
The x450 provides a scalable and flexible hardware platform. There are a
number of important aspects of the system hardware to consider when planning
your configuration. These are discussed in this section.
3.1.1
Processors
xSeries 450 servers combines copper-based, XA-64 Enterprise X-Architecture
technologies with 64-bit, Intel Itanium 2 processors.
Table 3-1 lists the processors standard in each x450 model and the part number
of additional processors.
Table 3-1
Processors in each x450 model
The L2 and L3 cache run at the full speed of the processor.
A total of four processors can be installed in the x450. One, two, three, or four
processors can be installed. Each processor within a node must be the same
speed and cache size. Each processor option includes the processor with
heatsink (pre-assembled) and its associated power module (which is referred to
as the
power pod
).
Processors must be installed in a specific order, as shown in Figure 3-1 on
page 41. Special tools are required to install the processors and these are
included in the option.
