W2K3 Clustering and NLB on the same machines

We have to put the App Server and DB server on the same machine, if we need
to have NLB for the web farm and clustering for DB, is this possible and
would there be any issue?

Hi,

I think this can be done but you need a nic for the heardbeat, cluster
public lan, and a nic for the NLB.
But for the NLB nic you must set the disable ( enable this network for
cluster use ) -cluster conf-networks.

Becarefull that the trafic goes to the right NIC.

I disagree with Robert on this.

No, do not do this, while you might be lucky and able to make it work.
A configuration like this would not be a supported or qualified
configuration.

do not do this.

Rgds,
Edwin.

It clearly states that it is not supported.

Hello Russ,

Russ is right on the money. Totally different clustering applications.

Edwin,

You are right it is not supported but it wil work.
Sometimes you need to make choices supported or not. I know the right way is
get supported but I see to often that customers build something that is not
supported, and choose for the "el cheepo "version

Pbx ask it it wil work and yes it can work but I for get to say it is in no
way supported and there for a bad solution.

Greetings,

Robert

Unsupported and High Availability do not go hand in hand. A company that has
a need for high availability would be violating many tenents of HA by using
an unsupported solution.

Sorry, but in my previous post, I should have clearly stated that it is my
opinion on the matter, and I can see that Robert agrees that it is a bad
idea.
