32 paths would require doubling the initiator or target ports beyond what the exhibit topology depicts, such as 4 HBA ports connecting to 4 controllers with 4 ports each.

With 2 host HBA initiator ports and 2 storage controllers each presenting 4 FC target ports, each initiator can form a path to every available target port, yielding 2 x 4 x 2 = 16 total paths. Multipathing software such as MPIO or DMP discovers and presents all 16 paths to the operating system, enabling load balancing and redundancy for the LUN.

8 paths would result from a reduced topology, such as 2 HBA ports connecting to 2 controllers that each expose only 2 FC target ports.

4 paths represent a minimal single-fabric configuration with 1 initiator port and 2 controllers each providing only 2 target ports, which is far fewer than shown.
