If you have 2 OSS'S that target one OST then you have redundancy on
that particular OST related to a failed OSS. But what redundancy do
you have for that OST itself (the SAN,NAS, or simple mount of a local
raid 5/6) fails. I of course do not mean the actual array , since
there would be a redundancy built into that system (raid) . But the
host server for the OST.
