Basic Administrative Procedures and Setup Completion Figure 18: NIC Properties, Teaming Controls tab, Load Balancing option Detailed information about these four load balancing teaming options can be found in the HP Network Teaming Help. ■ Transmit Load Balancing-All transmit IP frames are load balanced among all team members based on a Load Balancing algorithm in the teaming device driver. The Current Primary adapter transmits all other frames, and receives all frames for the team. If a failover event occurs, one of the non-Primary adapters assumes the role of Current Primary adapter, and transmit IP packets are load balanced among all remaining team members. If a failure occurs in any of the non-Primary adapters, the packets are load balanced among all remaining team members. ■ Switch-assisted Load Balancing-All transmit packets are load balanced among all team members based on a Load Balancing algorithm in the teaming device driver. The receive packets are load balanced among all team members by the switch. If a failure of any team member occurs, the packets are load balanced among the remaining adapters. There is no primary adapter in a Switch-assisted Load Balancing team. ■ Balance with MAC Address-This feature allows load balancing of IP packets among the teamed NICs using the last four bits of the MAC Address. (See following Note.) ■ Balance with IP Address-This feature allows load balancing of IP packets among the teamed NICs using the last four bits of the IP Address. (See following Note.) Note: The teaming utility can load balance IP packets among the teamed NICs installed in a server. The primary NIC in the team receives all incoming packets. The choice is available to load balance with the source MAC address (the address transmitted from the workstation) or the source IP address. Using the last four bits of either source address, the teaming driver algorithm assigns this source address to the port of one of the NICs in the team. This port is then used to transmit all packets destined for that source address. If there are four NICs in the team, the packets are received by the primary NIC on the team. The packets are retransmitted through one of the four ports. 5. Click OK to accept the team properties. NAS 4000s and 9000s Administration Guide 43
