Small server. 3 SATA drives (e.g. 500GB and 2x1TB). 1st drive is the root drive (contains o/s and Oracle). 1TB drives as used as raw devices by ASM for a normal redundancy diskgroup (effectively providing a mirrored diskgroup for the database).
ASM is usually used with RAC. Is ASM actually recommended for a single-instance (non-RAC)?

Billy, just make sure you never go over 50% utilization on a 2-device system. If you lose a disk ASM is going to have a lot of fun getting ASM to provide mirrored blocks on the other remaining device.
