receive flow control, and Jumbo Frame features of the Gigabit Ethernet Adapter and the
iSCSI Target. Tune network options and interface parameters for maximum iSCSI I/O
throughput on the operating system.
IBM System Storage N series
The combination of System p5 and IBM System Storage™ N Series as the first of a whole
new generation of iSCSI enabled storage products provide an end-to-end set of solutions.
Currently, the System Storage N series feature three models: N3700, N5200, and N5500.
All models provide:
򐂰 Support for entry-level and midrange customers requiring Network Attached Storage
(NAS) or Internet Small Computer System Interface (iSCSI) functionality.
򐂰 Support for Network File System (NFS), Common Internet File System (CIFS), and iSCSI
protocols
򐂰 Data ONTAP software (at no charge), with plenty of additional functions, such as data
movement, consistent snapshots, and NDMP server protocol, some available through
optional licensed functions.
򐂰 Enhanced reliability with optional clustered (2-node) failover support.
2.6.5 Fibre Channel adapters
The p5-550 and p5-550Q servers support direct or SAN connection to devices using Fibre
Channel adapters. Single-port Fibre Channel adapters are available in 2 Gbps and 4 Gbps
speeds. A dual-port 4 Gbps Fibre Channel adapter is also available. Table 2-7 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, 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.

2.6.6 Graphic accelerators
The p5-550 and p5-550Q 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.
In addition, the p5-550 or 5-550Q supports the POWER GXT4500P (FC 2842) and the
POWER GXT6500P (FC 2843) graphic accelerators, offering 3D graphics capabilities on the
