OK, Matt, good call. I do indeed see the merit behind the dutiful DBA shying away from the NFS protocol.

Things have changed a LOT over the last couple of years that I (only recently) consider ground-breaking in advancing the NFS protocol as a reasonable transport for Oracle I/O. In fact, I have been pleasantly surprised at throughput and processor utilization both. But, filers don't scale :) ( gotta expect a plug in there, right ) ?

I think the first place anyone should look at employing NAS is in redo logging believe it or not. That is, an NFS exported CFS comprised of LUNS in SSD. Offload the duress on the expensive SAN array head, service 100% of all lgwr flushes in 1ms flat and provision such redo for potentially dozens of Oracle Servers throughout the enterprise. Very simple way to get a quick boost. Talk to TMS and tell them I sent you :-) http://www.texmemsys.com/
