Two excellent explanations by Mr. Troth and Mr. Laflamme, they are right on. Thank you. The sad part is we set this scenario up to overcome POLITICAL boundaries between I/S fiefdoms and showcase the technologies. We do not do this in production.

Or ... airport hubs and multi-hop flights. You need to go from Nashville to Brimingham, but you're flying Delta. Well, Delta's hub is in Atlanta, so your trip will have a layover there. Might as well drive! Maybe you got a new office. You're spartan enough, so you can haul your stuff within the same building. Oh ... but there's a contract with some facility manglement firm, so you have to pay $300 for them to do it ... just because. And you have to wait. In this case, NFS brings more overhead. LOTS more. (Disclosure: I use NFS ... A LOT ... but I also know there are times one should not use it.) Using NFS to give Linux access to SFS files is ... like that Atlanta layover. Overhead makes z people ... well, twichy. (Some z people and other systems programmers actually shudder at wasteful overhead, though I that the concept is of no concern to ... er, uh ... Agile programmers.) (Ooohhh... I may have hit a nerve with that jab.) -- R; <>< On Fri, May 1, 2009 at 9:01 AM, Gary M.
