Yeah, after this research phase has been completed, we're going to have to go into a prototyping phase. I should be able to get funding for a half dozen or so x4100 systems to play with. We standardized on those systems for our Linux deployment. > test with your name service in the loop.

Tentatively I think I'd put automounter maps in LDAP, although doing so for both Solaris and Linux at the same time based on a little quick research seems possibly problematic. > Also, as you may know, Linux doesn't play well with hundreds of > concurrent mount operations.

I've done some initial testing of NFSv4, but never tried lots of simultaneous mounts... > At any rate, you may indeed be an outlier with so many file systems and > NFS mounts, but I imagine many of us are waiting on the edge of our seats > to see if you can make it all work.

I don't necessarily mind being a pioneer, but not on this particular project -- it has a rather high visibility and it would not be good for it to blow chunks after deployment when use starts scaling up 8-/. -- Paul B.
