Cisco DCNM vs Brocade BNA and other tools

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
