We are using this product for about 3 years now, so I think it's time to give some feedback here! Our customers can access our whole infrastructure from anywhere (Wifi or VPN) without having any impact of the speed nor performance problems - like with other switches we have used before which were not SDN compliant at all; they usually crashed when many users connected through their VLAN/VNI interfaces simultaneously as well.The only thing was missing sometimes but maybe because there might be another issue going on elsewhere. If you want an easy way out if your current setup has issues regarding reliability then go ahead otherwise just wait until new features come up later down stream :) This will save us millions yearly costs since most companies don't need thousands lines worth servers lying around idle waiting till someone wants them ;).We use mostly Cisco devices such as ASA firewalls etc., however the main point is how much money does one spend each year.
