What is the maximum number of disk shelves per loop in a fabric-attached MetroCluster?

• A. 2
• B. 1
• C. 6
• D. 4

Answer: (A)

In a fabric-attached MetroCluster, disk shelves connect over Fibre Channel loops to provide redundant paths. NetApp design limits how many shelves share a single loop to keep path arbitration simple and performance predictable. The maximum is two disk shelves per loop, so you don’t overload a loop and you retain reliable failover across the fabric. Having more than two on one loop isn’t supported and would risk performance and path management issues, while fewer would underutilize the loop’s capacity.
