[OpenAFS] OpenAFS or Coda?

[Nathan Neulinger]

You don't really provide enough detail of the nature of the file access
to give a reasonable answer.

Are the files being accessed equally from both sites, or predominantly
from one? Are they mostly being read, and only rarely written to?

Is one site subordinate to the other - i.e. a primary facility and a
small adjunct group off site?

Depending on the usage patterns, AFS may or may not be a good solution
for you. 

If primary access is read-only, and you don't mind some delays when
updates take place, you could easily put a file server at both sites,
and replicate the volume, with the RW copy of the volume being at the
site that does most of the RW accesses. 

For read-only accesses, the local replicate can be used, for RW, the
clients would talk to the remote file server if necessary.
