Using a Dell PowerEdge R750 server with a single Broadcom 57508 dual-port 100Gb network interface card, we found it offered up to 2.3x higher bandwidth than a configuration with four 25Gb NICs, as measured by iPerf synthetic tests. The 100Gb NIC solution also provided more consistent 100% bandwidth for multiple data streams. Testing showed the 100Gb NIC achieved significantly higher throughput compared to the four-port 25Gb alternative.

Using the synthetic iPerf test tool to compare two solutions:
Š A Dell PowerEdge R750 server with
Broadcom®
57508™
Dual Port 100Gb
network interface card
Š The same PowerEdge R750 server
with four 25Gb NICs*
We found using a single 100Gb
Broadcom 57508 NIC offered
Up to 2.3x the Gbps of a four-NIC solution
Plus, the 100Gb Broadcom 57508 NIC solution offered
100% bandwidth consistency for multiple data streams
