ZFS is addressing many of the enterprise filesystem features that would be needed to implement something on this scale, and there is the iSCSI target from NetBSD available in the ports tree. I think 7-RELEASE is going to be a solid foundation for building solutions like this - but in the mean time it may be worth considering OpenSolaris if are considering going the COTS path. or - you can take a look at a company like Isilon Systems (http://www.isilon.com/) which builds very scalable filers based on FreeBSD. I have beta tested their iSCSI implementation and it does look good. HTH -pete -- ~~o0OO0o~~ Pete Wright www.nycbug.org NYC's *BSD User Group
