Hello - we're waiting for EMC to come on site and install our new VNX5200 SAN. When we ask them what kind of switch is needed to host it, they say 10GB is highly recommended. This is an extra 15K, so we're trying to do a little research to see what other companies are using out there, and if the idea of trying to run the SAN over a new Cisco 3850 1GB switch is a really bad option, or if the SAN would perform fairly well. Is there anybody out there running this (or a similar) SAN over a 1GB switch and doing ok with performance? Thanks for your insight.
