In a production environment, the mirror pairs will be duplexed across two SAS/SATA controllers.
Duplexing the mirrors makes a concat/RAID1, and a properly configured RAID10, inherently more reliable than RAID5 or RAID6, which simply can't be protected against controller failure.
Stan, am I correct that this - dual/redundant controllers - is the reason that a real SAN is more reliable than just running local storage on a mod-high end server?
