Multi Node (N+1) SQL Fail over Cluster

Hi,

I would like to set up 2 Active Nodes and 1 Passive Node SQL fail over cluster. Please correct me if i am misunderstanding about ISCSI Disks configuration Like--

NODE-1, NODE-3 SQL DATA

NODE-1, NODE-3 SQL LOG

NODE-1, NODE-3 SQL TEMPDB

NODE-1, NODE-3 SQL SYSTEMDB

NODE-1, NODE-3 SQL MSDTC

NODE-1, NODE-3 SQL QUORUM

=======================================

NODE-2, NODE-3 SQL DATA

NODE-2, NODE-3 SQL LOG

NODE-2, NODE-3 SQL TEMPDB

NODE-2, NODE-3 SQL SYSTEMDB

NODE-2, NODE-3 SQL MSDTC

NODE-2, NODE-3 SQL QUORUM

Here NODE-3 is Passive NODE.

Thanks

Zahid
