ompared to enabling the same bandwidth
capability using four 25Gb NICs

While using multiple 25Gb NICs is an option to increase overall bandwidth of a server, our tests show that it may not optimize bandwidth usage as well as configuring your Dell PowerEdge R750 with a single 100Gb Broadcom 57508 NIC. Across tests using varying TCP stream counts, the Broadcom 57508 solution delivered higher bandwidth and more consistent performance than the same server with four 25Gb NICs. If your organization’s applications demand consistent, fast performance, consider equipping your PowerEdge R750 servers with Broadcom 57508 Dual Port 100Gb network interface cards.
