It looks like there is a consensus from people who do OS work:

	Gould                 - O. S. (un*x)
	Tandem                - O. S. (!un*x)
	Tolerant Systems      - O. S. (un*x)
	AT&T                  - O. S. (unix), SCSI only.

Does anybody from any of the DB corporations want to get a
short plug for the mirroring they provide?  Plus, we're always
interested in getting more OS opinions....

I am very interested in trying to get some standard benchmark
which will measure how fast these mirroring facilities do their
job.  In particular, I would like to see how mirroring in the
OS compares to mirroring in the DBMS (a problem since we don't
have anybody from DB corps who want to advertise their mirroring
facilities).

Does anybody here think that mirroring can be used to reduce the
amount of work in writing transaction logs (for rollback/recovery)?
