Disc mirroring - better use internal mechanism, or nvraid?

[Thona]

I havea couple of servers that I need t oget into better shape. They have the capability to have their discs mirrored. So that that has been done using nvraid.

Now, that has issues. We were never satisfied with nvraid - it has a tendency to disconnect the mirrors sometimes, the events it publishes are pretty bad for central administration. Driver maintenance for boot images is painfull.

The question has been raised whether we would be better just ignoring nvraid and going with dynamic discs and the integrated mirror mechanism.

Anyone any experience for that?

The idea is to use that (i.e. the dynamic disc mirror) and then a boot dvd to actually boot into the mirror disc. That boot handling is my biggest problem, gigen that nvraid handels that transparently.

Can anyone with experience comment on that? Is there a better way to handle the boot from a failed mirror by now, compared to using a bood disc/boot cd?
