I am currently working through a try and buy of the WAAS solution.
I have a data center connected via a T1 to a remote site. I have included an image of the test design. All three appliances are WAE-512's. As noted in the visio, I am using wccp for redirection.
As of now, CIFS optimization is great. I have been surprised at how well it works. To the user, being able to transfer a 50MB file over a T1 WAN link in a matter of 10 seconds is amazing.
The problem that I'm having is all other optimizations aside from CIFS. I can transfer a 3MB FTP file between sites multiple times, and it takes a minute each time. I would expect DRE to make the results similar to what I am experiencing with CIFS.
I am seeing the same lack of results with HTTP, backups, and any other bulk-data apps.
I forgot to include on the Visio that the WAES are version 4.0.11 b34.
Under the application policy's on the WAE's, I have the following:
map adaptor WAFS transport
name WAFS All action optimize full
map other optimize full
