Currently the driver does not support native command queuing, port multiplier or port selector functionality." The driver source isn't available (or I couldn't find it) so it's not easy to confirm. > I'm also pretty sure the LSI supports NCQ > I'm not 100% sure though Both the LSI chipsets implement SAS, which can support SATA. Since SAS supports TCQ, it's at lease conceivable that NCQ support was added for SATA. I looked at the mpt_sas driver code a bit and didn't see anything, but I'm not sure if the TCQ -> NCQ conversion is transparent to the driver, or if it's handled in the scsi drivers, etc. -B -- Brandon High : bh...@freaks.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
