Thanks very much for the reply. I kind of suspected that. The thunderbolt works well with the recent mini-macs and I already have it connected to one as a backup device, it would be simple enough to export on NFS and that would do the job. The way I'm planning the app, there would be multiple BBBs accessing the file system plus they would use standard db IO for sql. Given that each BBB would be handling a single web service request (start to finish of one state), I think NFS would be adequate. I had just hoped to take advantage of the raw performance of the Areca RAID we use. You've settled the architecture for me and it's easier to set up a prototype this way. Thank you.
