Crap. I just saw this now. I submitted a kickstarter:
https://www.kickstarter.com/projects/597419130/1111180831?token=ace70d75
I can cancel this if you’re pretty far along.

sadly my current employer has not expressed any interest in that
effort. anyone want to help subsidize the effort ?
For what it's worth, we're already working on an xhci driver at
Joyent.
It's something I'm working on as we know there's a lot of need
for this
around the community.

spinning SAS disks but a very good SLOG like the HGST SSD800MH.B,
which cost around $800 AUD. The reason being that in a well built
SmartOS box, you’ll have ZFS ARC occupying RAM from which a good
portion of your database reads should be sourced from and when
sync writes do need to be done, the SLOG will help make them more
performant. ARC makes read performance exceptional for a cache
hit. As for zpool layout, for database workloads your better off
with a multi-way mirror (i.e. a pool full of mirror vdevs) as
when there is an ARC miss it should be performant (at least won’t
incur parity penalties in RAIDZ).

have for SmartOS are Intel based ones (be they integrated onto
the motherboard or as an add-in card), I’ve not had any issues at
all with LSI (now Avago) HBA cards whereas on-board SATA/SAS can
be hit and miss unless they are also LSI based (but can be
painful to reflesh if needed). The USB compatibility aspect is
becoming more important as Illumos doesn’t yet have an
appropriate driver which can cause boot issues and rules out
keyboard interactions - some boards have the ability to emulate
USB2, but some work and some don’t.

the devs all poo-poo the use of consumer-grade disks, and sata in
general. and they have made great cases for doing so. but for
most of my uses, the price and potential performance looks
extremely attractive. i don't usually have the ability to drop a
couple of thousand dollars into a disk subsystem for these small
installations. the customers typically already have enough
hardware to run everything bare-metal, but i've tried hard to
virtualize everything for the many benefits provided by doing so
(plus of course the ones specific to using smartos/zfs).
