"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I'm not 100% on these numbers, but I'm pretty sure it's somthing like:

Traditional SunOS (aka Solaris 1.x): 2gig max file size, 2gig max filesystem size (might have been 4 gig on later releases), and ~64k files/filesystem.

Early 2.x releases with BigFiles support in the filesystem: 2 gig max file size, 2^64-1 max filesystem size, and 2^32-1 files/filesystem.

Recent 2.x releases (i.e., 2.7): 2^63-1 max file size, 2^64-1 max filesystem size, and 2^64-1 files/filesystem.

The bottom line is that these maximums are essentially infinite in 2.7.
