- No, but I'd like to see a software-only solution to the problem. Sun's
- disk utilities are pretty elegant. They use the standard SCSI hardware
- including the Sbus SCSI interface. The mirrors work through the
- installation of 'metadisk' drivers, that take care of writing to the
- 'submirrors' transparently.
-
- This eliminates the need for specialized controllers and 'expensive' RAID
- setups. If performance is a problem, I think 10Mbit SCSI should eventually
- fix it.
-
- As more and more NeXT's are pressed into server roles, mirroring, striping,
- and other high-availability technologies will be needed.
-
- How about it NeXT?
