If you have 2240 systems, max number of nodes in SAN cluster is 4 ( 2x HA)
If you have 2500 or 3200 systems, max number of nodes in SAN cluster would be 8 nodes (4x HA)
Any other models - 12 nodes (6x HA)

If you have mix of systems, the smallest system will determine max number of nodes in your cluster.
