A customer is attempting to connect a new VNX array to an existing, redundant FC fabric. Each FC fabric consists of a Cisco MDS9513 switch connected to an MDS9148 switch. The VNX storage processor FC ports are connected to available ports on the MDS9513 in each fabric.
After completing the FC connections between the VNX array and the MDS switches, the customer proceeds to configure the appropriate zones via the MDS configuration interface, but the VNX storage processor FC ports are not visible to the switches. What is a likely cause of this lack of visibility?
A. The MDS9513 port groups to which the VNX is connected already contain an ISL port.
B. The FC cables used for the VNX-to-MDS connections are too short.
C. The VNX storage processors are configured with insufficient write cache.
D. The VNX FC port properties are configured with an incompatible interface type.
A customer has implemented MirrorView/A.
What determines the upper limits for MV/A performance?
