Re: Support for mirrored pair as root disk?

I'm sort of a fan of Hardware RAID.  Computer sees a BIG disk,
and goes, per normal.

Makes TONS of sense when external RAID way outperforms soft RAID
and it's portable (CPU caught fire?  Move the disk to a duplicate
hardware and boot, HA is easy enough like this too).

For lower end RAID, I just don't know the prices.  It would SEEM that
some hardware type folks might figure out that that a 68030 (or ARM)
with a bunch of RAM, a ROM and a gang of (cheap) IDE drives and a SCSI
host interface might find a home in the sub-$2000 RAID section.  Put
the elevator algorithms on the ROM and don't worry too much about how
slow IDE is.

I've got a RAID box here that *sustains* 40MB/s reads and we're
getting 30+ for writes.  Wicked expensive, but when you need to

If only I could get *BSD on a 4-way alpha...
