At one point I worked with a MS SQL Server cluster and it required a special driver. This driver would do things like automatically switch ports/hosts depending on which box was the hot and which was the spare. I'm pretty sure we couldn't use the ODBC one because that was only driver that we could get (Java on AIX) and it didn't work well with the cluster.
