I would like pointing you to a Cisco customer reference story - a migration to Connectrix MDS 9700's / MDS 9148S's: [URL]…  We used the DCNM slow drain analysis to identify some bottlenecks without much effort. The tool shows were and when Buffer to Zero conditions are occurring and the related drop and reset counters, too. Critical values are highlighted "red" or "yellow" - I have never seen a better tool!  We increased buffer credits between UCS fabric interconnects and the MDS 9700's and deployed F-port channels. End device ports - providing up to 100 B2B's - got more credits on the switch side for performance, too. After that, no high B2B to zero conditions were visible.  Some MDS highlights are: Port monitoring will be pre-configured. Frames having errors will be dropped - no defect frame will be forwarded to unsettle any end device. If required, ports will be error disabled. Input- / output queuing will prevent from running into head of line blocking situations. The crossbar architecture will guarantee equal latency and high throughput for all I/Os.   The customer feedback is:  Last but not least: DCNM is able to discover vSphere, Dell EMC and other vendor storage through SMI-S providing end to end monitoring capabilities from a VM to a single LUN.    I hope this customer experience will help.  Best regards,  Swen
Hello users and Experts, One of our big customer request that we evaluate the difference between Cisco and brocade offer about Monitoring tools and Advanced feature. Actually, they use Brocade Gen 5 Director and BNA with MAPS and they would to know if advanced function ant tools are better from Cisco (think about Slow Drain Device, monitoring bandwith, Buffer utilization, performance, diagnostic and troubleshooting, etc..)  Do you have some customer experience, personal experience and documentation about that please ?   Thanks for you help. Regards, Mat
