Performance and Recommended Use of AB545A 4-Port Gigabit Ethernet Cards

Features and Benefits of the AB545A

Features and benefits of the AB545A include:

• The Gigabit Ethernet ports support virtual LANs (VLANs). A Virtual LAN (VLAN) is a

logical or virtual network segment that can span multiple physical network segments.

VLANs isolate broadcast and multicast traffic by determining which destinations should

receive that traffic, thereby making better use of switch and end-station resources. With

VLANs, broadcasts and multicasts go only to the intended nodes in the virtual LAN.

• The Gigabit Ethernet ports support Jumbo Frames with a maximum transmission unit

(MTU) of 9000 bytes. Jumbo frames achieve much higher throughput than the standard

1500 MTU before reaching optimum CPU utilization.

• Supports Ignite UX. Ignite-UX (IUX) is an HP-UX administration toolset to help you install

and configure (or recover) HP-UX systems.

• Supports HP Serviceguard and Auto-Port Aggregation (APA) for high availability.

• Supports PCI-X online addition/replacement (OLA/R) on specified systems.
