2.2.7. I/O
Module
The I/O module is connected to the crossbar interconnect via two 2.4Gbps interface cables. It
has eight PCI slots compatible with 133MHz PCI-X bus, allowing up to eight PCI cards to be
mounted. To support standard option I/O interface, one base IO card can be mounted.
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 main cabinet. A maximum of four I/O modules can be
installed in the main and expansion cabinets, respectively.
