2.6.6 Graphic accelerators
The p5-520 and p5-520Q support up to four enhanced POWER GXT135P (FC 1980) 2D
graphic accelerators. The POWER GXT135P is a low-priced 2D graphics accelerator for
IBM System p5 servers. This adapter supports both analog and digital monitors and is
supported for System Management Services (SMS), firmware, and other functions, as well as
when AIX 5L or Linux starts an X11-based graphic user interface (GUI).

2.6.7 InfiniBand Host Channel adapter
The p5-520 and p5-520Q support the RIO-2 expansion cards (FC 2888) to connect the
supported additional I/O subsystems. The server also supports one GX Dual-port 4x
InfiniBand Host Channel Adapter (FC 1812) that enables the attachment of the Topspin
Server Switch models 120 and 270. Only a single GX Dual-port 4x InfiniBand HCA or RIO-2
expansion card can plug into the system planar, using the GX slot, at a time. Connection to
the Topspin Server Switches is accomplished by using the 4x IB Cables.

Topspin Server Switch models 120 and 270
Switches are the fundamental components of an InfiniBand fabric. An IBM System p5 server
proposal might also include the Topspin Server Switch model 120 and 270 in an initial system
order.

The Topspin Server Switch models 120 and 270 are programmable switching platforms that
consist of a switched multiple-terabit interconnect and an intelligent control architecture. The
high-bandwidth, low-latency interconnection is extremely adaptable. The switches enable an
outstanding level of application scaling, rapid deployment, and resource consolidation.

2.6.8 Asynchronous PCI-X adapters
Asynchronous PCI-X adapters provide connection of asynchronous EIA-232 or RS-422
devices. If you have a cluster configuration or high-availability configuration and plan to
connect the IBM System p5 servers using a serial connection, the use of the two default ports
is not supported. You should use one of the features listed in Table 2-8.
