A PowerMax Storage Group has Host I/O limits set at 10000 IOPS. The Port Group contains four ports across different directors. The Dynamic Distribution is set to OnFailure.
What is the maximum IOPS the Storage Group can achieve in the event a switch port being used by one of the director ports fails but the director remains online?
If a switch port being used by one of the director ports fails but the director remains online, the maximum IOPS the Storage Group can achieve remains at 10,000 IOPS. This is because the Host I/O limits are set at 10,000 IOPS, and the Dynamic Distribution set to OnFailure will redistribute the I/O load among the remaining ports in the Port Group. Thus, as long as the director itself is still online, the storage group can achieve the maximum IOPS.
Correct answer D In the event that a switch port being used by one of the director ports fails but the director remains online, the maximum IOPS the Storage Group can achieve is 10,000 . This is because the Host I/O limits are set at 10,000 IOPS . The Dynamic Distribution policy is set to OnFailure, which means that if a port fails, the system will automatically redistribute the I/O load to the remaining ports in the Port Group . Since the director remains online, the Storage Group can still achieve the maximum IOPS of 10,000
