easy questions related with A-P cluster

Hi everyone,

I'm just a newbie with clustering.

We've got a 64-bit A-P cluster running with Sql25k 64-bit too.

Each node own two local network adapters. One of them (the one currently is Active) own three IP and the another one only one.

Why? From CLUADMIN I see as one of these three is set as Cluster IP Address in Active Resources. So I see the following configuration for the Active node:

Adapter 1: IP public for Active Directory

Adapter2:IP1 (reserved or ?)

IP2 (used as SQL IP Address 1 in Active Resources)

IP3 (used as Cluster IP Address in Active Resources)

Passive node:

Adapter 1: IP public for Active Directory

Adapter2:IP (only have one ?)

Is this correct/necessary? Does anyone have similar configuration?

Thanks for your time,

Does anyone have any idea?|||

This issue has already solved.

Ip1: physical node

Ip2: virtual cluster

Ip3: virtual Sql
