2.8.4 Fibre Channel adapter
The 570 servers support direct or SAN connection to devices using Fibre Channel adapters.
Table 2-10 provides a summary of the available Fibre Channel adapters.
All of these adapters have LC connectors. If you are attaching a device or switch with an SC
type fibre connector, then an LC-SC 50 Micron Fiber Converter Cable (FC 2456) or an LC-SC
62.5 Micron Fiber Converter Cable (FC 2459) is required.
Supported data rates between the server and the attached device or switch are as follows:
Distances of up to 500 meters running at 1 Gbps, distances up to 300 meters running at
2 Gbps data rate, and distances up to 150 meters running at 4 Gbps. When these adapters
are used with IBM supported Fibre Channel storage switches supporting long-wave optics,
distances of up to 10 kilometers are capable running at 1 Gbps, 2 Gbps, and 4 Gbps data
rates.
Table 2-10 Available Fibre Channel adapters
2.8.5 Graphic accelerators
The 570 support up to four graphics adapters. Table 2-11 provides the available graphic
accelerators. They can be configured to operate in either 8-bit or 24-bit color modes. These
adapters support both analog and digital monitors.

2.8.6 Asynchronous PCI 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 p servers using a serial connection, the use of the two system ports
is not supported. You should use one of the features listed in Table 2-12 on page 48.
