Recommended Configurations For Nft Environments; Network Fault Tolerance Only With Preference Order; Nft With Preference Order Applications; Transmit Load Balancing With Fault Tolerance (Tlb) - HP Rx2620-2 - Integrity - 0 MB RAM Manual

requires fault tolerance in case of a network adapter malfunction, but does not have a demand
for receiving or transmitting more than the capacity of the Primary port.)

Recommended Configurations for NFT Environments

HP recommends the following:
• Heartbeats should be enabled (default).
• MAC addresses should not be manually set to a locally administered address (LAA) via the
Microsoft Adapter Properties User Interface. An administrator should not implement LAAs
on individual ports that are members of a team; otherwise teaming may not function correctly.
Setting an LAA for the team is permitted via the NCU.
• Spanning Tree's blocking, listening, and learning stages should be disabled, or bypassed,
on all switch ports to which an HP Integrity Network adapter team port is attached. These
stages are not needed when a non-switch networking device (for example, server) is attached
to the switch port. HP ProCurve switches have a feature called STP Fast Mode that is used
to disable these Spanning Tree stages on a port-by-port basis. Cisco switches have an
equivalent feature called PortFast.
• Team members can be split across more than one switch in order to achieve switch
redundancy. However, all switch ports that are attached to members of the same team must
comprise a single broadcast domain (in other words, same VLAN). Additionally, if problems
exist after deploying a team across more than one switch, all team members should be
reattached to the same switch. If the problems disappear, then the cause of the problem
resides in the configuration of the switches and not in the configuration of the team. If switch
redundancy is required (in other words, team members are attached to two different
switches), then HP recommends that the switches be deployed with redundant links between
them and Spanning Tree be enabled (or other Layer 2 redundancy mechanisms) on the ports
that connect the switches. This helps prevent switch uplink failure scenarios that leave team
members in separate broadcast domains.

Network Fault Tolerance Only with Preference Order

Network Fault Tolerance Only with Preference Order is exactly like Network Fault Tolerance
Only except that it allows the SA to rank teamed ports with a User Ranking. This user ranking
(or preference) is used by the teaming driver as a criterion in deciding which teamed port should
be the Primary port. Teamed ports are ranked higher or lower than each on the Team Controls
tab on the Team Properties page. In addition, the User Ranking mechanism is listed in the
Mechanism Priority list box on the Advanced Redundancy tab on the Team Properties page. The
User Ranking mechanism is always ranked lower than any other advanced redundancy
mechanisms (for example, Active Path or Fast Path). Otherwise, if User Ranking had a higher
priority, the other advanced redundancy mechanisms would be effectively disabled.
For all other aspects of this team type operation, refer to

NFT with Preference Order Applications

Network Fault Tolerance Only with Preference Order is mainly used in teaming configurations
where one or more teamed ports are better than others. For example, an NFT team of a Gigabit
network adapter and a Fast Ethernet adapter could utilize Preference order to rank the Gigabit
adapter higher than the Fast Ethernet adapter. As long as the Gigabit adapter is in a good state,
it will rank higher than the Fast Ethernet adapter and will be the team's Primary port.

Transmit Load Balancing with Fault Tolerance (TLB)

Transmit Load Balancing mode, previously known as Adaptive Load Balancing (ALB),
incorporates all the features of NFT, plus Transmit Load Balancing. In this mode, two to eight
ports may be teamed together to function as a single virtual network port. The load-balancing
algorithm used in TLB allows the server to load balance traffic transmitted from the server.
