To the original question, the parts we use at Joyent can always be found at http://eng.joyent.com/manufacturing. Those are the ones with which we have direct experience and in which we have the most confidence. We always recommend using our Certified configurations. Notice that we don't use L2ARC; demand for it in JPC has been limited to nonexistent (I wonder if you're really sure you need it).
I should also mention that the Mach16 is EOL and HGST/STEC have not come out with a replacement for it (Keith's pet peeve #464: vendors who EOL good hardware without providing a similar replacement). As such, you may have difficulty sourcing that part. The S840z is a fine substitute for it in the same form factor, and is much faster; however, it's also much more expensive. HGST has unfortunately put me in a situation where I am unable to recommend any of their products for use as a slog in the same price range as the Mach16. Unless they come out with something great later this year, we'll probably be stuck with the DCS3700. I see from the manufacturing docs that you have a single 50GB device (270-022 usually). From reading around it seems to be recommend that the slog be mirrored as it is taking the writes and if one fails there is a spare. Do you find having only the one slog device is ok ? Also what sort of performance change / increase could one expect from using and slog device, we have the DCS3700’s ? I am trying to understand the way the slog works and how much improvement I can predictably expect from an SSD slog ?
