A customer has implemented a second Brocade director into their environment. They have moved several hosts and one of their two storage arrays onto the new director. When a large batch cycle was run, the customer experienced queuing on the directors when previously there was none.
The customer discovered the following during their analysis of the issue.
The hosts running the batch cycle used storage from both arrays.
The only LUNs having problems came from the array attached to the new director.
When the batch process was rerun with all LUNs made available through the original director, no problems were encountered.
What would you recommend to solve the performance problem?

A.
Add departmental switches to the fabric, creating a core/edge design

B.
Change FSPF costs

C.
Implement additional Brocade ISLs

D.
Utilize Brocade ISL Trunking to optimize the ISL traffic
