GREATER BANDWIDTH HEADROOM PROVIDES EXCELLENT SCALABILITY

Although the Cisco UCS offers scalable bandwidth to each Cisco UCS 5108 Chassis, up to

a fully redundant 40 Gb/s, in our testing we used a single redundant pair of 10Gb connections to

the fabric interconnect. Figure 2 shows that the peak bandwidth usage of the 175 concurrent

virtual desktop sessions never exceeded 450 megabits per second, or roughly 5 percent of the

bandwidth available. Note that this 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 Login VSI test results. The bandwidth afforded by the Cisco UCS architecture provides

sufficient headroom for excellent scalability as your IT staff adds more Cisco UCS B230 M2

server blades to support larger user populations.
