Clustering DHCP
This is all in a Test lab.
I need some help with clustering dhcp. Here is what i have so far, i have 2 DHCP servers point to a single database on a 3rd machine. This is need because clustering does nothing for the DHCP database. My problem is i really do know much about setting up a cluster. I have configured the NICs on both machines (Public and Private). Communication is working well. Cluster Service account is created.
My question is how to setup the cluster. i really do under stand much about the Quorum. Where does it need to be stored. I have read i should put in on a seperate drive on the server, not a partition. I have also read about SANs, but i and currently not using one. Is the Quorum heald on each machine and replicated to eachother or something else?
Any direction would be great

I am running Server 2003 Enterprise on all machines. Forgot to notate that. We do have a SAN in our production network, but not in the test lab. So i cant produce what i want without the SAN?
I realy need to come up with a solution for this because our network is so large. We have about 7000 to 8000 DHCP clients in 433 Scopes. About 1200 Reservations that can not be lost. I copy the database to the backup server daily, but this is getting old.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Normally clustering uses shared disk that each server has access to via SCSI or FC. The shared disk is usually presented in several LUNS to the servers in the cluster. One shared LUN is generally used by the Quorum and you need a second one for the shared DHCP database.
You can use a local quorum or a majority node set in 2003, but you are using 2000 and that is not available.
Until you get shared disk, I would stick with 2 DHCP servers following M$'s 80/20 rule for scope overlap.
