Well, SAF-TE is pretty anal-level, and it's more about enclosure and other details. I'd have to fully research _what_ is exactly required -- at the SCSI card (probably not much), at the SCSI backplane (probably not much) and at the SCSI driver (there's the majority of the beef ;-). Now, case-in-point/back-to-original-focus: 3Ware Escalade, Areca ARC and other _true_ hardware ATA cards are _not_ SCSI-2 cards that provide SCSI-2 feedback to the kernel. They have added some capabilities, like smartd and other daemon support. But to get the failed/hot-swap capability, you _must_ let the internal ASIC/microcontroller -- where _all_ of the "meat" is -- manage the array. At this point, anyone who doesn't believe what I'm saying can feel free to assume I'm pulling it all out of rectum. Because I've said enough, dissected this all enough and I'm sure most people who don't care are sick of hearing me try to explain why you can't use 3Ware cards with software RAID and handle failures or hot-swap. And I still want to strangle anyone on the software RAID lists for continuing to proliferate such. ;-> -- Bryan J.
