Well, as long as it's just storage, I'd recommend just having it as a single volume. The only use case for partitions is (in my opinion) operating systems, where they serve as some sort of primitive quota system, preventing /var from filling the entire disk and making your system unbootable :)

As for filesystems, XFS is really nice for large volumes. I prefer ZFS, but that's not really an option on Linux (and that is, in fact, one of the reasons I switched to FreeBSD) :)
