We have a Mac server (10.7) with a 200TB disk array. We're trying to decide between HFS+ and the unsupported ZFS. Which should we use, why, and is there another choice that we haven't considered?

"(Un)Supported" would seem to be the key word here. If you end up with data loss/corruption from using an unsupported filesystem, Apple will likely tell you to get lost and use the FS that ships with the OS. – James O'Gorman Feb 14 '12 at 21:45
I agree with @JamesO'Gorman. I love ZFS but it's not a good idea to do anything that the vendor considers unsupported (unless you're comfortable with the potential consequences). – Mike B Feb 14 '12 at 21:47
We are a CS department and have been using ZFS on another server for more than a year without incident. I wonder who it was who felt the need to down vote my question. Apple doesn't even support 200TB on a server. – vy32 Feb 14 '12 at 21:57
How good is your backup system? How much down-time can you afford if that system dies, and you need to do a restore? – Zoredache Feb 14 '12 at 22:05
@tonny Do what our compsci department did. Use FreeBSD and zfs. – sysadmin1138 Feb 14 '12 at 22:39

If I read this correctly, there is no practical limit the the size of filesystem you can create with HFS Plus. ZFS is unsupported, so unless you're using this for a throwaway scratchpad, your only choice is HFS plus.
