For example, if ZFS is mirroring a pool across two different storage arrays, a

from a firmware error.
In this case ZFS is going to help. I agree. But how often you meet such solution
(mirror of two different storage arrays) ?
I have never seen this for cabinet-sized storage systems, because they offer the
ability to perform on-line maintenance. But I do see mirroring to two arrays for
small arrays, which typically do not offer on-line maintenance.
