If the files being accessed across the pond are often the same files, some of NetApp's filer caching products might be of use. That way, once the files were cached locally, only the updates would need to go across the pond.

We've got two NetApps, an F740 and an F87. The big 'un is in our US office, and the little guy is in our UK office.

We've got a T1 between our sites, and of course the performance sucks for those who access files on the other side of the pond.

I'm wondering about possible mirroring options. From what I've heard, all of them are one-way. There is no such thing as a two-way style of mirror, is there? For example, if a user opens a file on one side, it would lock the file on both filers, and then when he saves it, it is synced to both sides.

Otherwise, the only thing I can do, really, is set up particular directories to mirror over, and so we'd have a read-only copy of the local folder on the other side, and vice versa. Not really the most useful thing for collaboration.

Anyone have any good solutions to such a problem?

thanks
