Hi,

I'm looking to replace a problematic Marvell PCIe SAS JBOD controller
from Supermicro, type AOC-SASLP-MV8. (mdadm freaks out on it and the
controller drops the drives - there has been discussion of the problem
on the list. Seems to be a mvsas driver problem but seems to surface
only under mdadm use.)

It's a nice controller, but we have to get an array going, so I'm
shelving the Marvell card and getting a new one. I'll be using mdadm
raid5 / raid6 over the controller.

This one, LSI SAS 3081E-R, looks good with eight SAS ports for around $200:

I can't find anything concrete regarding Linux, but I did find a
known-good confirmation for Solaris/ZFS here:
http://jmlittle.blogspot.com/2008/06/recommended-disk-controllers-for-zfs.html

Can anyone confirm/deny that the PCIe JBOD controllers from LSI work
on Linux out of the box? Or give other recommendations for 8 port
controllers in the $150-$200 range? (Or thereabouts. It'd be great to
know about any known-good 4-port controllers for even up to $250.)

Thanks!
