Thanks guys. I'm just shocked that there isn't a hardware solution for this. The way I would like it setup is that theres a Master controller, and a Slave controller. The Kernel driver would know of both of them and only send data to the Master. If there was a major error, it would switch to the Slave, and run off that. To link the Master and Slave I would just use PCI-E 16x, and or a cable between the two, kind of like Nvidia SLI. And if the driver was smart enough, send data to both, so if the card dies right in the middle of a commit, the other side will for sure get the data. Im sure theres a smart way of doing it. Yes I know doing Software RAID 1 in Linux is very possible, but I don't want to have to deal with another layer of disk access. Also this isn't a huge array, only ~400MB, and using SAS :)
