Base Module
855-900549 2-4
2.2.2 Base Module
A base module is composed of cells, iSP cards, I/O modules, power bays, and DPSs.
2.2.3 Expansion Power Bay
The expansion power bay is used only when the power is supplied from two systems or
100VAC. It is never used for a single power supply system.
2.2.4 Cell
A cell is composed of up to four processors, a CPU node controller, a memory controller, and
main memory. The main memory can vary from the minimum 2GB to the maximum 64GB. At
least one cell needs to be installed for the base module. Up to two cells can be installed.
2.2.5. I/O Module
The I/O module provides 8 PCI slots corresponding to 133MHz PCI-X buses, allowing up to 8
PCI cards to be used.
The PCI card can be inserted or taken out in online mode (hereafter called the “hot swap”) with
some exceptions. Consequently, the base module need not be shut down or rebooted each time
the PCI card is added or replaced. High availability is achieved with this implementation (note
that the OS that supports this implementation is required).
One core module or HDD module is mounted on the I/O module. At least one core module is
required for each partition.
A DVD-ROM unit is installed in the I/O module as standard equipment. In addition, a DAT unit
and up to four 73GB/146GB/300GB magnetic disk units can be installed as optional units.
At least one I/O module is required for the base module.
