This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enigFB00EC361EB9741C2944583D Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Hello, I used this card for my personal ZFS NAS (2 cards, 15 disks + 1 SSD). http://www.supermicro.com/products/accessories/addon/AOC-SAT2-MV8.cfm Frankly speaking, this card will work 99% of the time. But it has a few quirks : - Sometimes, I've had a port drop because maybe of a broken/dying disk. The port would NOT recover unless I cold rebooted the server. And a port not recovering means, even the BIOS option ROM programming won't find it. Quite annoying as one could guess. - I could panic a system by removing a drive (back in the 8.1-RELEASE days) because of thread locking/sleeping issues. - I don't know what is to blame for that but : - I had more than once odd queue issues and disks flapping. Not really a problem with ZFS but VERY irritating nonetheless. - I even had a whole controller drop on me once. Nothing a reboot/zpool scrub couldn't fix (with NO corruption to boot!) but still... - It really, REALLY doesn't play nice with other cards. I tried migrating progressively to mpt(4) cards, with a one by one switch, only to experience stray NMIs and pretty ugly kernel panics. It turned out having a "pure" system with two f the same kind (mind, I was not pairing PCI-X and PCIe, this was in every case pure PCI-X setups) did wonders for stability. It's probably fairly decent for most home purposes (my main use), but I'd advise against it in any serious environment.
