I am interested in accessing large datasets (10's of
GB) from a centralized storage facility to clients
on remote workstations - cross country (5000Km),
perhaps even overseas.

Due to the latency introduced by the geographical
distance, not all applications will perform satisfactorily
accessing remote files.  In such cases the entire or
interesting parts the file would have to be (say)
FTPed to the remote workstation and accessed locally.

However, for applications remotely accessing
chunks of data sequentially or nearly so, AFS may
perform satisfactorily (using double buffering, etc).
The local caching of AFS would even allow for
a considerable amount of random accessing and
still be more attractive than FTPing the entire
file over and doing local access (esp. if the
data access is random over the entire 10's of
GB file).

Are there any white-papers, or any other documents
that would give an indication of LAN vs WAN performance
of AFS - any application or data access profile would
do since I have nothing at this time (my search has
just begun)?

Ditto for databases running over AFS (LAN vs WAN
performance).

Thanks for any help.  Please email if you have
any comments or questions.
