I'm currently looking into implementing DFSR, with the following setup:
2 Offices in the US 2 Ofices in Europe
The offices are currently using a NAS where I just copy stuff when needed, and have VPN connectivity over 20MB lines.
It will be around 1TB of files, mostly big static files, and a few little files that will be accessed/edited more often (think ms office files).
Is there a way to know what hardware would be needed to implement DFSR at my scale ? I've read about I/Os requirements, but will it be a bottleneck for me with max 40 to 60 people accessing the DFS at the same time?
