I am looking at moving forward on a Riverbed Steelhead solution. I have a hub and spoke network with all WAN links being full P2P T1's. I have sites ranging from 20-45 people. The main problem that I am trying to solve is server centralization at the hub site.
As of now, with sites that have a server centralized at the hub site, anytime someone try's opening a 3MB+ email, or transfers large files to a file server, there is a significant delay. I am looking for improvement on CIFS, SMB, and MAPI.
Does anyone have experience with either the Riverbed or WAAS? As I said, the Riverbed seems to be the fully baked solution, but I'm looking for thoughts on the WAAS as well.
