Veritas costs a lot more, for one.  It has the ability to let you grow/shrink
filesystems, take snapshots of a filesystem for backup, all kinds of stuff. 
DiskSuite can only let you grow if you have another slice available; it's 
entirely slice-based.

Veritas has two big downsides:  1.  It looses slice information on the mirror
of a mirrored root disk, and 2.  Since it's not intergrated with the OS,  good
luck booting from a CD and trying to repair damaged filesystems.

What we do at work is use DiskSuite to mirror the root disk, and use VM for all
the other storage.

Netstat might have what you need.
