Refer to the exhibit. Server 1 fails to connect to the storage array over the Storage Area Network (SAN) of the Cisco NDS 9000 Series Switch. The requirements are to redesign the storage network and k

Enabling NPV and F-Port-channel on the ports facing Server 1 allows the Fibre Channel switch to operate in NPV mode, virtualizing server HBAs and aggregating them into a logical F-Port-channel towards the core fabric. This provides redundancy by bundling multiple physical links, isolates server traffic from the core fabric, and facilitates fault tolerance for hardware/software failures and nondisruptive upgrades by abstracting the server's connection.

Creating a SAN port channel that faces the storage device provides link redundancy for the storage array, but it does not address the server-side requirements for redundant and isolated traffic, nor does it inherently tolerate failures and upgrades of the SAN fabric devices connected to the server.

Adding an additional supervisor to the Fibre Channel switch enhances the switch's internal redundancy and supports nondisruptive supervisor upgrades, but it does not directly solve the problem of providing redundant and isolated server traffic paths across the SAN fabric.

Placing an additional Fibre Channel switch to create two physically independent storage fabrics is a method for fabric-level redundancy, but the question specifically asks for an action that addresses the server-side connection for Server 1 to meet the specified requirements, which NPV and F-Port-channel directly solve more effectively in this context.
