GREATER BANDWIDTH HEADROOM PROVIDES EXCELLENT SCALABILITY
Although the Cisco UCS offers scalable bandwidth to each Cisco UCS 5108 Chassis, up to
a fully redundant 80 Gb/s (160 Gb/s in an active-active configuration), in our testing we used a
single redundant pair of 2 x 10Gb/s connections to the fabric interconnect. The peak bandwidth
usage of the test never exceeded 700 megabits per second, or roughly 3 percent of the
bandwidth available. See Appendix D for details. Note that the peak usage includes all storage
and virtual desktop traffic. This shows that the chassis capacity far exceeds the required
bandwidth for virtual desktop users based on our test results. The bandwidth afforded by the
Cisco UCS architecture provides sufficient headroom for excellent scalability as your IT staff adds
more Cisco UCS B200 M3 server blades to support larger user populations.
