switch vendor redundancy mechanisms to make a single switch highly redundant.
For example, Cisco provides an option called High Availability on some switches.
This option allows a Cisco switch to have redundant Supervisor modules.
An HP customer using a Cisco switch with redundant Supervisor modules and
redundant power supplies can create an SLB team, a Dual Channel team, or a
Dynamic Dual Channel team of several ports, connect the team to two modules
inside the same Cisco switch, and enable High Availability. This provides
transmit/receive load balancing, network port fault tolerance, switch power supply
fault tolerance, Supervisor fault tolerance, and switch module fault tolerance. This
option is usually more expensive than purchasing a license to use Dual Channel or
Dynamic Dual Channel.
B.B.1.24 Which switch Port Trunking/Port Bonding technologies is SLB (Switch-assisted
Load Balancing) compatible with?
FEC/GEC, Load Sharing, MLT, IEEE 802.3ad (Static mode – no LACP), and so on
B.B.1.25 Which switch Port Trunking/Port Bonding technologies is Dual Channel
compatible with?
FEC/GEC, Load Sharing, MLT, IEEE 802.3ad (Static mode – no LACP), and so on
B.B.1.26 Which switch Port Trunking/Port Bonding technologies is 802.3 Dynamic
compatible with?
IEEE 802.3ad (Dynamic mode – using LACP)
B.B.1.27 Can I connect teamed ports to more than one switch?
Yes, with NFT, TLB, and Dual Channel teams only. Also, all switch ports that have
teamed ports connected to them must belong to the same broadcast domain. This
means that the broadcast domain must span between the switches.
B.B.1.28 What is the limit for the number of teams I can create in one server and what is
the limit for the number of network ports that I can include in one team?
The theoretical limit is 16 teams of 8 network adapter ports per server. This is defined
as a “theoretical” limit because very few servers will allow the installation of enough
network ports to create 16 teams of 8 network adapter ports.
B.B.1.29 Which HP Integrity Network Adapters can I team together? (or) Can I team together
embedded network adapter ports with standup network adapter ports? (or) Can
I team together ports from more than one standup network adapter? (or) Can I
team together Intel-based HP Integrity Network Adapters with Broadcom-based
HP Integrity Network Adapters?
One of the main benefits of HP Integrity Network Adapter Teaming for Integrity
customers is its flexibility to support teaming together ports from almost all HP
Integrity series Network Adapters. HP Integrity Network Adapter Teaming supports
teaming ports together from HP Integrity Network Adapters with Intel or Broadcom
ASICs, whether the ports are embedded ports (LAN on Motherboard – LOM) or
ports from standup network adapters. Support for a specific team type or advanced
feature (for example, offloading) may vary depending on the combination of HP
Integrity Network Adapter ports.
