Hi,

Yes KMS, it works, little to no speed difference, with 6.5.x you only
get a maximum of 2 key groups though, e.g. two volume groups that you can
use, with 7.0 there are more.

I believe(?) the first version that supported it was 6.5.2, but it has been
awhile.

For the OS, good question, also note, I've seen issues if your tape drive
isn't a certain firmware rev in relation to the HBA firmware, the backups
break and the fiber hba/link resets it self, make sure to do a lot of testing
first.

Justin.
