I’ve been re-visiting the whole Riverbed vs Cisco WAAS situation again. We have a few WAAS appliances and modules in production, and they do the job – for now. I am concerned about the scalability of their solution and it is my opinion that Riverbed has the edge here and in other areas – except price. I’m not one to really care about price usually because I am more concerned with the outcome – but sure it is a consideration for the business. Hence, I’ve gone back to have a look at it all again.
Watch the Riverbed video here
It is impressive stuff. Cisco has the edge on price – but not much else. Riverbed is a clear winner when it comes to ease of deployment, scalability and technology. I’ll come back and justify my comments with some data soon.

And the part 2 of riverbed vs cisco????
Yeah – I’ve been slack on the updates. Long story short – Cisco WAAS stays and the new 4.1 version of the software is an improvement. In my opinion the Riverbed is better but sometimes other factors (eg $) come into the company’s decision process. So far, the WAAS has not failed us; but I strongly urge full evaluation testing of either vendor to make sure the right one is suitable for your environment.
mate just noticed this, still waiting on that update.
Any day now mate I’m sure of it
