After about six months of meetings, decision matrices, PoCs, etc. we have narrowed down our SD-WAN choice to SilverPeak or VeloCloud. One factor that may make the final determination is how the tunnels are created (WANOP is considered a nice-to-have, but not a determining factor).
For Velocloud, tunnels are dynamic and most of our sites would have an appliance that supports 25 or 50 tunnels.
For SilverPeak, the tunnels are static, but most of their units support 2000 tunnels.
We have caught wind of a potential concern with the SilverPeak tunnels in that, the more sites that are deployed, the longer the SilverPeak units take to build all the tunnels.
My main question is - has anyone had any SilverPeak experience with 100+ sites? Do the turn-ups become unbearably long at any point (like, over 20 minutes)? Have any performance issues been encountered as more sites get added? Any limitations reached?
