Something like a dell md3000 has dual raid controllers with path failover, and mirrored cache.
-----
Some hba can be used with software/OS mpio for card to card path failover. Some dual port raid cards support port failover, but only on the same card.
Are there any mainstream raid cards that support card-to-card failover of raid sets?
Are there any mainstream raid cards that support mirrored cache between two cards, in the same system?
