Correct, no additional IOPS out of using both ports on the same processor. If you have large IO size and want large throughput, you will get more throughput from both ports combined than a single port. Not double though since you will still likely run out of IOPS capability before hitting bandwidth limit. Since an FA will typically run out of IOPS before bandwidth, you are saving a switch port by not using the second port on the processor. i.e. One port is usually plenty to fully exercise the FA CPU.
VMAX FA port 0 and 1 of any FA director share the same processor like FA-1E0 and FA-1E1 use same processor. That mean IOPS supported with FA-1E would shared. My question is if we use only ports 0 of all FA and leaving port 1 unused then what are Pros and cons of this ? Assuming we don't cross the mapping limit of FA i.e. we have less devices than can be mapped to any FA.
Pros and cons of using both ports for single processor on VMAX FA
