as possible. We have failover everything in the box, and we will use carp to setup multiple boxes. In each, I want to do hardware RAID. Initially I bought the 3ware SATA RAID card, but its not supported. I then moved to an Adaptec 1210SA, which I now know only does software RAID. What are the options for hardware RAID for SATA drives on AMD64? Any advice would be greatly appreciated.
For hardware RAID with a PCI controller, devices supported by ami(4) are your best bet: LSI/Symbios 523 SATA is listed - from an archived list post, these are 150-4 and 150-6.
Some Dell CERC-SATA are supported too, but (again from list posts) others are Promise junk.

[ bit of a reliance on archived list posts here, but when I asked recently for anyone using any ami(4) not listed in the doco so I could prepare a diff, I had a total of one reply, so list archives is the best I can do.. I'll wait a couple more days before sending it in case seeing this encourages anyone else to mail me, though I highly doubt it ]
There are SATA-to-SATA mirroring controllers too, see faq (at least one of them had a box that fits anywhere in the chassis - arco, accusys, etc).
Or assuming there's a socket, there's the cheap solid-state option of CF cards in a CF-IDE converter. Not RAID but it may do what you want.
