Performance against Cisco UCS IBM can deliver up to 77% lower server to server latency1 IBM communications stay within the chassis at less than 1 microsecond (us) Node to SI4093 to Node Cisco communications must exit the chassis and go to the Fabric Interconnect adding an extra step, meaning you have the latency of the Fabric Extender (0.65us) and Fabric Interconnect (2us) to consider. Node to FEX to UCS6k to FEX to Node Latency 3.3us = 0.65us + 2us + 0.65us Communication between blades requires traffic through Nexus 6100 Nexus 6100 Cisco UCSManagement Performance IBM has separate management ports Cisco UCS has management traffic going over the same networking ports as their data!5This is an IBM internal study of IBM PureFlex System solution designed to replicate a typical IBM customer workload usage in the marketplace. The results were obtained under laboratory conditions, and not in an actual customer environment. IBM's internal workload studies are not benchmark applications, nor are they based on any benchmark standard. As such, customer applications, differences in the stack deployed, and other systems variations or testing conditions may produce different results and may vary based on actual confi guration, applications, specific queries and other variables in a production environment. Prices, where applicable, are based on published US list prices for both IBM and competitor, and the cost calcul ation compares the cost per request for the 3yr life of the machine. 3 year total cost of acquisition comparisons are based on similar expected hardware, software, service & support offerings* Notes IBM would require twice the Ethernet Modules in certain configurations 6.
