a. Each compute module has four internal PCI/PCI-X slots; however, the lowermost slot of the base compute module
is required for the IO9 PCI 66 MHz card. Therefore, only the two topmost slots are available for PCI/PCI-X cards
while the third slot down, which is on the same bus as where the IO9 card is installed, can only support a PCI card
running at a speed of 66 MHz or slower.

The base configuration can consist of 2 to 8 processors. A system that contains 2 or 4
processors requires one base compute module. With this system configuration, you can
add one PCI expansion module or one MPX module to your system. If space is available
in the rack, you can also add SGI TP900 storage modules to your system or you can add
additional storage racks to your system.
A system that contains 6 or 8 processors requires one base compute module and one
expansion compute module that are connected together with a NUMAlink cable. This
system configuration does not allow you to add a PCI expansion module or an MPX
module to your system. However, you can add TP900 storage modules or storage racks
to your system.
The components of the base configuration can be placed on a table top or housed in a 17U
rack or a 39U rack. Each rack can contain more than one system, as shown in Figure 2-6.
