Some veritas documentation in the past had the values backward.

mirror-stripe is the classic (easy) mirror of stripes.. stripe-mirror is the layered stripe of mirrors. It looks like that page is fine except for the 1+0 and 0+1 headings. I don't like them anyway because they're too easy to get backwards.

from that page: RAID 0+1 has the same fault tolerance as RAID level 5

Really?

Why would the applications between 1+0 and 0+1 be different?
