HP Integrity Server

Unlike NFT and TLB, SLB does not utilize the concepts of Primary and Non-Primary ports within

a team. All ports within a team are considered equal and perform identical functions as long as

the particular port is in a functioning state. The algorithm for load-balancing transmit traffic

used by SLB is identical to the algorithm used by TLB. Unlike TLB, SLB load balances all traffic

regardless of the protocol being used.

Network Addressing and Communication with SLB

SLB functions identically to TLB (refer to the section,

with

TLB", and the scenarios described in that section) except in its use of MAC addresses. SLB

requires a switch capable of grouping multiple switch ports as a single switch port and SLB

teaming uses the same source MAC address for all frames transmitted on all teamed ports in the

same team. This does not violate IEEE standards because the switch is fully aware of the port

groupings and expects that all teamed ports may transmit using the same source MAC address.

The algorithms for load balancing transmit traffic used by SLB is identical to the algorithms used

by TLB [see the section,

The switch connected to the SLB team determines which load-balancing algorithm is used to

load balance receive traffic for the team. An SLB team does not control which teamed port in the

team receives the incoming traffic. Only the switch can choose which teamed port to use to send

the traffic to the server. Therefore, consult the switch manufacturer to determine the algorithm

the switch uses.
