Since this paper mentions that the designers first tried their implementation on FreeBSD 2.2.7, I thought I'd ask here if anyone has ever heard of this file system. If so, is this something that is available in FreeBSD or is this just an interesting academic exercise? If this isn't is use, why? Also, if not in use, is there another file system (by another name) that does something similar? This file system sounds like a great idea. A link to get the paper I mentioned is here: http://www.hpl.hp.com/personal/Alistair_Veitch/papers/elephant-hotos/index.html Andy
