At our December 6 meeting, Dave Hitz of
Network Appliance gave a presentation on the history of NFS
and some of the latest implementation details and protocol changes.
Dave described the appliance market and detailed
some of the difficulties in creating a new market for "filer" appliances.
He also shared some of his insights into the innards of their product
including the software based RAID4 and Write Anywhere File Layout (WAFL)
Dave, along with some other folks, have written a USENIX paper called:
"NFS Version 3 Design and Implementation".
