Zach I am upgrading my satellite network of eight C2811 routers from existing packet accelerator device to WAE-502 modules using WCCP. Do I also need WAVE appliance for this deployment and if so which model, add-ons and licenses would I need?
At a minimum you will need an external appliance to function as the WAAS Central Manager. For a deployment of this size, the smallest appliance (WAVE-274) will be fine.
Where are the servers/applications located that these sites will be communicating with?
