Keith, Krishna - thanks for your answers.  I think I've worked it out,
and wonder if you can confirm my understanding of gluster:

Gluster uses servers and clients.  A client can access a gluster
resource without requiring the use of any local disk space -
effectively mounting the remote server locally.  A gluster server
actually holds the files.  You can have any number of servers and or
clients.  To achieve ultimate read performance, and where disk space
isn't a constraint, you could run gluster server on every machine, and
configure it to read locally.  This would mean that for 1GB of data,
you'd need 1GB of storage available on every single machine.

Is this right, or have I misunderstood?

Thanks,


Rob
