(NFT) provides the safety of additional backup links between the server and hub/switch. Dynamic
Dual Channel NFT is implemented with one channel team providing a primary adapter and another
channel team providing a secondary, backup adapter(s). During normal operations, if the adapters
in the primary team fail, a link to one of the adapters in the secondary, backup team automatically
takes over.
• 802.3ad Dynamic Dual Channel NFT and Preference Order (INP).
Available in the ProLiant Essentials INP only. Provides the same options as 802.3ad Dynamic Dual
Channel NFT except it offers the additional option of setting the priority order of the adapters that
are used in the primary and secondary channels.
• Switch-assisted Dual Channel Load Balancing (INP). Available in the ProLiant Essentials INP only.
There must be a minimum of two adapters in a dual channel team and a minimum of one adapter
per group. One group of team members is treated as a Switch-assisted Load Balancing (SLB) group
to one switch, and a second group of team members is treated as an SLB group to a second switch.
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. Only Gigabit adapters can be used for Switch-assisted Dual
Channel Load Balancing. When you select Switch-assisted Dual Channel Load Balancing, the Team
Members window becomes Team Members Grouping and displays two windows labeled Group 0
and Group 1. The up and down arrows are used to assign the members to be in Group 0 and
Group 1. If a team contains an iSCSI-enabled adapter, you cannot use the Switch-assisted Dual
Channel Load Balancing (INP) setting.
• Switch-assisted Dual Channel Network Fault Tolerance (INP). Available in the ProLiant Essentials INP
only. There must be a minimum of two adapters in a dual channel team and a minimum of one
adapter per group. Switch-assisted dual channel Network Fault Tolerance (NFT) provides the safety
of additional backup links between the server and hub/switch. It is implemented with one channel
team providing the primary adapter and a second channel team providing the secondary, backup
adapter(s). During normal operations, if the adapters in the primary team fail, a link to an adapter
on the Secondary team automatically takes over. Team members can be moved to Group 0 or
Group 1 on the Team Properties Teaming Controls tab.
• Switch-assisted Dual Channel NFT and Preference Order (INP). Available in the ProLiant Essentials
INP only. Provides the same options as Switch-assisted Dual Channel Network Fault Tolerance
except it offers the additional option to select the priority order of the group (Group 0 or Group 1)
used for the primary and secondary channels.
• 802.3ad Dynamic with Fault Tolerance. All team members are dynamically placed into a port-
trunk/channel by dynamic protocol agreement (LACP) with the switch. A failure of a team member to
synchronize joining a port-trunk or channel with the switch is treated as an error and that team
member is considered failed. 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. If a team contains an iSCSI-enabled
adapter, you cannot use the 802.3ad Dynamic with Fault Tolerance setting.
• Switch-assisted Load Balancing with Fault Tolerance (SLB). SLB increases a server's throughput using
Fast Ethernet or Gigabit Ethernet ports. SLB load balances all traffic. Unlike TLB, SLB can be
configured to increase both transmitting and receiving channels between your server and switch. For
example, an SLB team containing four HP Fast Ethernet adapters configured for full-duplex operation
would provide an aggregate maximum transmit rate of 400 Mbps and an aggregate maximum
receive rate of 400 Mbps, resulting in a total bandwidth of 800 Mbps.
