Gigabit Ethernet Features

The AD221A, AD222A, and AD393A cards have the following Gigabit Ethernet features and requirements:

• Supports Jumbo Frames. Because Jumbo frames reduce a server’s CPU processing of network packets, efficiency

increases especially for heavy traffic. The same amount of data can be transferred in less frames. The Jumbo Frame

maximum transmission unit (MTU) size is from 1501 to 9000 bytes.

• Supports virtual LANs (VLANs) for increased flexibility. A Virtual LAN (VLAN) is a logical or virtual network segment

that can span multiple physical network segments. VLANs also more efficiently use switches and end-stations by sending

broadcasts and multicasts only to the intended nodes. For more information on this feature, please see Using HP-UX

VLANs on http://docs.hp.com.

• Supports Auto-Port Aggregation (APA) for load balancing and single-system failover.

• Supports configuration through the NCWeb portion of the System Management Homepage (SMH) or command line

nwmgr on HP-UX 11i v3.

• On board Checksum Offload (CKO) to enhance server efficiency and performance over TCP, UDP, and IPv4.

• IPv4 TCP Segmentation Offload (TSO). TSO, also known as “large send” enables a system’s protocol stack to offload

portions of outbound TCP processing to a network interface card thereby reducing system CPU utilization and enhancing

performance.

• LAN boot support on HP Integrity systems.
