Why is traffic not being load balanced out of my server? (or) Why is traffic not
being load balanced during backups?
Either TLB or SLB is required for load balancing of transmit traffic. NFT will not
provide for any type of load balancing.
HP Integrity Network Adapter Teaming uses either the MAC or IP address of the
destination, or the TCP port information in the frame to make its load-balancing
decisions. If the destination always has the same MAC and IP address (another
server or client), no load balancing will result. If the destination has the same MAC
address but the IP address is different (for example, several clients on the other side
of a router), then HP Integrity Network Adapter Teaming needs to be configured
to load balance by TCP port or IP address instead of by MAC address. HP
recommends using the Automatic method for load balancing.
Why is traffic not being load balanced into my server? (or) Why isn't traffic being
load balanced during backups?
A team type of SLB, 802.3ad Dynamic or Dual Channel and a supporting switch are
needed to achieve receive load balancing. Receive load balancing is determined by
the switch connected to the HP team in SLB mode. If the HP NIC team is configured
for SLB, then receive load balancing should occur if the switch is configured properly.
Consult the technical resources provided by the switch manufacturer.
I am trying to team two NICs for load balancing but the system will not let me.
Why? (or) I have an HP NC series Fast Ethernet adapter and an HP NC series
copper Gigabit Ethernet adapter in a TLB or SLB team but I can not add an HP
NC series fiber Gigabit Ethernet adapter to the team. Why?
To team multiple ports together for load balancing, all ports must be capable of
supporting a common speed. For instance, any 10/100 port can be teamed for load
balancing with a 100/1000 port because both ports support a common speed. The
ports don't have to be operating at the common speed. Teaming a 1000 fiber port
with a 10/100 port is not supported for load balancing because the ports don't support
a common speed.
What is the difference between HP's load-balancing teams and Microsoft's Network
Load Balancing (NLB) or Window's Load Balancing Service (WLBS) features?
HP teaming provides for fault tolerance and load balancing across network ports
and is aimed at server resilience. Microsoft's NLB and WLBS are for fault tolerance
and load balancing across servers and are aimed at application resilience.
Can I use HP Integrity Network Adapter Teaming with Microsoft's NLB or WLBS
features?
Yes, however, some special configuration may be required. Support is limited to
NLB and WLBS in Multicast mode only, not Unicast mode.
What effect will teaming have on the use of Cisco's Hot Swap Router Protocol
(HSRP) or the IETF's Virtual Router Redundancy Protocol (VRRP) in my
environment?
None. HSRP and VRRP operate independently of teaming.
Can I use HP Integrity Network Adapter Teaming in conjunction with Cisco Local
Director?
Yes, teaming will work correctly with Cisco Local Director.
I want to force a locally administered MAC address on my HP Integrity Network
adapter team. How should I do it?
Open the HP Network Teaming and Configuration Properties GUI (NCU). Click the
appropriate team in the GUI interface and select Properties. Go to the Settings tab
and type the LAA address in the Team Network Address field.
