Geographically Diverse file-replication

Hi all,

I'm working on something at the moment where I will require file replication across geographically-diverse networks.

Initially this will probably be multiple sites within the UK, however it is hoped that it will expand to global datacentres.

We're currently using NetApp 6080's to serve up the files and I'm wondering if anyone can recommend a good way of syncing the data (nearly 5 terabytes) so that updates made in one location are distributed to all the others in the shortest time possible.

In the first instance, I'd be looking for a single point of publishing with multiple points of distribution (I guess it's a standard "master-slave" relatoinship if it was a database!) hoever I want to head towards "Multi-Master" replication at file-sytem level!

Thanks in advnace for all your thoughts,
