If it's very busy, you may need to look at GigE. With the price of GigE adapters I wouldn't consider anything else. I have a huge database that takes about an hour to copy. The netApp snapshot feature is very nice because I can get a moment in time image of the database. Even though I can't run from the snapshot because it is read only (*) and PG needs to write to files just to open the database, I can copy it and get a runnable version of the DB. If I copy directly from the original I can get many changes while copying and wind up with a copy that will not run. (*): It would be nice if PG had a flag that allowed a database to be opened in read only mode without touching anything in the directory. -- D'Arcy J.M.

The filer would be mounted on a rh linux server (7.3), 4g RAM, dual cpu with a dedicated card for filer. I'd appreciate if anyone could share your experience in configuring things on the filer for optimal performance or any recomendataion that i should be aware of.
