Roy,
Why not use ZFS on Linux? (http://www.zfsonlinux.org)
ZFS on Linux is being merged into the upcoming Lustre 2.4 parallel
filesystem release.

Since these students produce rather large amounts of raw material, typically to be stored during the semester, we may need some 50-100TiB, perhaps more. I have setup systems with these amounts of storage earlier on ZFS, but may be using Linux MD for this project. I'm aware of the lack of checksumming, snapshots etc with Linux, but may be using it because of more Linux knowledge amongst the sysadmins here. In such a setup, I guess nearline SAS drives on a SAS expander will be used, and with the amount of storage needed, I won't be using a single RAID-6 (too insecure) or RAID-10 (too expensive) for the lot. In ZFS-land I used smallish VDEVs (~10 drives each) in a large pool.
