I have build a lot of OmniOS boxes and was involved in a lot of
hardware decisions. All of them are using LSI HBAs in raidless IT mode.
If there was ever a consensus in the Solarish world regarding disk
controller than this:
- prefer pure HBAs, avoid hardware raid cards, use those with IT

We use ARECA 1882 series cards in all our OmniOS storage servers.
We moved from a Linux/GlusterFS environment to OmniOS/Comstar and our
benchmarks have been very similar between the two using these controllers.
I highly recommend them, they have been very reliable for us, and
performance has

High quality RAID cards don't just perform simple passthrough, even thou we
would expect this to be all that is needed in a ZFS implementation.
The controller will (at least in Areca's case) utilise writeback caching to
improve performance, driver implementation is also a major factor in

The only problem I have consistently seen is if I hotplug a sas expander
with or without disks attached it will crash the system at least half the
time. I have simple resolved never doing that hot.
I have stuck
