I've spent some time looking at the capabilities of a few controllers based on the questions about the SiI3124 and PMP support. According to the docs, the Marvell 88SX6081 driver doesn't support NCQ or PMP, though the card does. While I'm not really performance bound on my system, I imagine NCQ would help performance a bit, at least for scrubs or resilvers. Even more so because I'm using the slow WD10EADS drives. This raises the question of whether a SAS controller supports NCQ for sata drives. Would an LSI 1068e based controller? What about a LSI 2008 based card? -B -- Brandon High : bh...@freaks.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
