- The shadow feature was introduced long before RAID controller
technology was as widely available as it is today.
- The shadow feature is an extremely "expensive" disk operation -- all
writes are duplicated in the engine *software*.
I would recommend in the STRONGEST POSSIBLE TERMS that you investigate
the use of OS level or controller level disk mirror/RAID solutions,
instead of shadows.
