The demand for higher-speed, always-on network connections is growing at a tremendous rate in order to keep pace with the requirements of I/O-intensive applications such as database backups, 3D modeling, animation,  video, Web serving, and more. Data centers  process terabytes of data daily. Processing, sharing, and distributing this data requires faster and faster networks and greater levels of connectivity. Today, even many desktop tasks and applications require 100Mbps speeds or faster!  HP offers a suite of 10/100Base-T  Ethernet LAN network interface cards (NICs) for every networking requirement. From the basic single-port 10/100 Ethernet NIC to the 4-port 10/100 NIC to the 2-port 100Base-T and 2-port SCSI Combo adapter, HP provides a standards-based networking solution  or every need. All of the Ethernet/Fast  Ethernet NICs are tuned for high performance and high availability on the HP-UX servers. The HP Ethernet/Fast Ethernet LAN adapters fully support the IEEE 802.3 and 802.3u standards. These scalable network links allow  ustomers to move large amounts of data quickly while leveraging their existing investments in Ethernet technology. Based on the same Ethernet standards already widely deployed in the marketplace, the HP LAN adapters protect customers’ investments by allowing them to migrate from 10 to 100 Mbps quickly and easily, with fast deployment and minimal training. Use of the HP Ethernet adapters not only enables customers to implement streamlined high-speed networking projects but, with the multi-ported cards, also reserves valuable I/O slots in their enterprise servers. In addition, most HP Ethernet/Fast Ethernet adapters support HP-UX VLANs (Virtual LANs). This software-based solution offers IT Managers a powerful tool that simplifies the tasks of building, managing, and securing complex network infrastructures. Physical LANs can be segmented into smaller logical or “virtual” LANs, allowing broadcast traffic to be reduced, thereby improving overall network performance. Now a change to network topology no longer requires those dreaded trips to the wiring closet! HP-UX VLAN is compliant with host-based IEEE 802.1Q VLAN tagging, IEEE 802.1p (later incorporated in IEEE 802.1D) priority encoding, and IP Type of Service (ToS)—802.1p priority conversion. Other key features of HP-UX VLAN include:

 • IP subnet-based, protocol-based, and port-based VLAN support

• 1024 VLANs per NIC port

• designed to work seamlessly with HP high-availability products, such as MC/Serviceguard

• no changes to applications required

• preserves VLAN configuration across reboot
