[ale] Fault Tolerant High Read Rate System Configuration

[Jim Kinney]

multi-pci bus (not just multi pci _slot_) mobo with several add-on
SATA300 cards. Hang fast drives from each card matching the aggregate
drive throughput to the bandwidth of the pci bus slot. Make pairs of
drives on different cards be mirrors. Join all mirror pairs into a
stripped array for speed.

Use entire drive for each mirror slice so any failure is just a drive
replacement. Add extra cooling for the drives.
