Hi all, we are thinking about moving to a iSCSI SAN for our SQL and Exchange processes and I was hoping to get some advice on how the features of 2005 or sQL 2008 will allow us to have the highest availability while using the best amount of resources.

We're currently running:
SQL 2000
One server holds three live databases
the other 3 servers are currently setup as readonly's
We also have a Netscreen load balancer that balances the readonlys.

My question is:
If we upgrade to SQL 2005 and have a SAN, is it possible to cluster the 4 servers together for data pulling from the SAN, or do I still have to have a single "live" server that processes all the inserts and updates?

Tnx.

Yes you can cluster servers together if they share a SAN.

I don't understand your question about the live server and processing inserts/updates.

From our front end (ColdFusion), we have to select a DSN for the SQL server that it should be using for the SQL Inserts/Updates. In the case of the SAN, does it matter which server is doing the inserts?

Using a SAN does not change how you have things setup.
