Each half of each PowerVault (7 disks) is connected to one of the channels on the Adaptecs. Four channels in all. As far as changing things, what do you mean? The cause of the failure is likely heat as we've had some AC issues recently. I didn't use mdadm.conf at all. All disks are partitioned with one 'Linux raid autodetect' partition. mdadm had always found the array automatically at boot.
