This is true for current hardware however I am attempting to reuse our
existing hardware that has been pulled from our production systems. It
tends to be older technology but still usable. In this case, it is a
set of disk arrays using SCSI3 drives.

While all of this is true I was kind of hoping that I could come up
with something that was more "plug and play". The LessFS looked
promising. I will continue to check this concept out further (be it
LessFS, ZFS, or something else) but I am going to be avoiding the bleeding
edge and can only afford to spend a limited amount of time
chasing this down before I have to bite the bullet and go with what
we have.

Thanks again of your feedback and to all the others who have responded.
Everyone's comments have been greatly appreciated.
