Clustering: Designate a Hot-Standby Unit (Raid-5 style)

If one is concerned about up-time, it doesn't make sense to have a cluster where all units must be functional to handle the load.

Clustering should allow the use of a Hot-Standby unit for the Cluster, for example running two 320's as active with a spare 320 (thus more affordable) in reserve. Allows for true N+1 setups without paying always for the +1!

        It's been under review for over 26 months, so it should either be upgraded to "Planned" or the notation deleted.

        This could be an automatic thing. Install a 2-node license and bring up a total of four nodes, HA creates a Master on the first unit, a ***** on the second, a Hot-Standby on the third and ignores the fourth. When Master or ***** goes down, the Hot-Standby takes over as the ***** and the fourth node becomes the Hot-Standby.
