Would you please expand upon this, because I'm really interested

Hi James - just the man I have a couple of questions for... :)

Will the LsiLogic 3041E-R (4-port internal, SAS/SATA, PCI-e) HBA work as a
generic ZFS/JBOD SATA controller?

It does (I've used it).  Kind of.

When I've had it attached to an external JBOD, it works fine with only
1 or 2 drives, but when the JBOD (promise j300s) is fully populated
with 12 drives, it flakes out (I/O errors).  Windows had no problems.

It works better with the LSI drivers than the Sun mpt driver.

Sorry I don't remember many more details than that.  You can search
on comp.unix.solaris for a thread a few months ago about it.

It only works on x86.

I ended up selling it and the JBOD, just couldn't get it working reliably.
