1.4.6 N to N Configuration (Scalable)

An N to N or scalable configuration has all servers physically connected to all multihost disks. Data services can fail over from one node to a backup, to another backup, a feature known as cascading failover.

This is the highest redundancy configuration because data services can fail over to up to three other nodes.
