We are planning to have WAAS solution in our corporate. It is a small setup with 3 sites. We are thinking of using the SRE module in the WAN routers. While going through the documentations a need for additional Central Manager is mentioned. Just wonder is it really required to have it considering a small setup?
It depends on what type of optimization you will require at the small site, for example I am confident that HTTP content, video streaming, basic transport and enterprise license optimizations should still work without a CM ( I have never done a lab without a CM so I am speaking from my experience)
Please keep in mind that a WAAS system without a CM is not supported!! in addition it will be very difficult to troubleshooting anything without the CM anyways.
The CM performs the role of a centralized point of configuration for multiple WAE's even if they are just 2 or 3 WAE's it is still as important as it is for a big deployment.
Without a CM, you won't be able to take advantage of CIFS prepositioning, SSL key management, or secure store (WAE disk encryption) and you won't be able to use the nice graphical reporting charts that WAAS CM provides ( to see what exactly is WAAS doing on your network from your small office to your data center or wherever the traffic is going to)
in regards Virtual WAAS ( as refered on the previous comment ) you might want to take a look at the following links:
