I have been assured by my manager that a compatibility matrix between NICs in Dell server hardware (example: PowerEdge R720 with Broadcom BCM5720) and switch hardware (example: Brocade NetIron CER-2048CX-AC) exists.  

I have been unable to find one online.  After being transferred 9 times by Dell technical/sales/customer services, I gave up there and have come here for an answer.

Does Dell do such compatibility testing and if so do they have a document (aka compatibility matrix) with their findings?

Thanks!
