defining ip address as a resource

[anatheilper]

Hi, I'm new to the mscs, and I wanted to know if I can do the following in it:
I want to define a rsource group which contains an application and ip, so that in case of a failover, the application and the ip failover together to the other node at the cluster, and it is possible to communicate with that application by using the ip defined in its resource group ( although after the failover, it's not the ip of the machine the application is in). If it's possible, hwo do I define it? do I need additional hardware?(nics?)
Thanks a lot,
Anat.

Once your cluster is setup you can totally do this. This is exactly what the cluster service is designed to do.

Create a resource group, add a resource for the IP address. Add a resource for the service. You will also probably need to setup a shared disk as a cluster resource as well. You can also setup a network name for the IP address. This network name needs to be unique on your network.

In order to setup a cluster you need to have shared storage such as a SAN.

If you don't have shared storage available you can look into setting up a load ballancer with a 100/0 share ratio. This way all traffic goes to one machine, and in the event of a failure the traffic would then go to the backup machine.

If the application stores data on disk, then you would need shared storage. It's not always necessary; it depends on the application. You could always use an MNS quorum and FSW. A print cluster is an example where you might not need the shared storage (if you're ok with losing the queue on failover).
