Eric,
I'm the other guy Paul has been mentioning. I added an Intel 32GB X25-E
to a J4400 this morning. It's attached to an X4240 via an LSI 1068E
based HBA. The system is also running NexentaStor (again, based on b104
ON bits). I added the SSD as a slog device and have been running iozone
to generate activity, and FMA hasn't flagged the drive yet.
That's very useful information. Is this the same drive that produces
bad data under diskstat when in a X4500, or is it just another drive of
the same type? If it's the former, then it's a clear indication that
there is a bug in the kernel SATL framework. I can try to come up with
a utility that constructs a SATA pass-through command to get the
underyling SATA datat (this will only work in the J4400).
Thanks,
- Eric

This system also has an Intel 32GB X25-E installed in one of the X4240's
SAS slots, connected to the internal Adaptec RAID controller. No FMA
complaints there either.

I'm in a position to run more tests if needed, as none of this hardware
is in production yet.
