NLB questions |
|
|
I'm new to Network Load Balacing. I installed two Windows 2003 servers in a
test environment. I have some questions to make.
Each server has two NICs. One is connected to the intranet (10.1.x.x
addresses) and the other is connected to a private switch shared only by
this two servers (192.168.x.x addresses).
1) I created a cluster (with NLB manager) in the 10.1.x.x adapters. Is that
correct?
2) How do I tell NLB to connect to SERVER2 via the private network
(192.168.x.x) to "configure" the cluster?
3) Is it common that each host send 1-2 packets per seconds through the
10.1.x.x adapter?
Thanks a lot! |

That is fine.

You cannot. The second NIC can be used to configure a totally seperate
cluster or can be used to connect for admin of the cluster. All traffic
pertaining ot the NLB cluster on the 10.1.x.x network will go over that
particular NIC.

So what's the big deal about having two NICs. Why does NLB recommend that
configuration?
What do you mean with "connect for admin of the cluster". Are you talking
about NLB Manager application?
Thanks! |

Well, in Windows 2003 you can configure multiple NLB clusters on a single
node but on different NICS. You could not do that in earlier versions. We
normally suggest a second card to use for administering the node while
cluster traffic stays on the NLB NIC. There is no requirement for 2 NICS,
it is more for convenience and to keep unnecessary traffic off the NLB
network.

If you have a 2 node NLB cluster you can just use one NIC in each node and
enable Multicast.
For a active/passive type 2 node cluster (with shared storage) you need a
seperate card in each server with say a crossover cable - depending on NIC's.
