[Veritas-bu] 9840 tape drive question
To echo Johnny: I sure wish I had the capacity of the 9940B, and FC is
definitely the way to go.

I don't think you will get that performance out of the drives in a mixed
On very large files it should work, but on normal fileservers you will have
to have a lot of multiplexing to get it.
If you don't need the extremely fast loadtime and positioning of the 9840B
drives I would look into 9940B. They are faster (except for load and
positioning) and they can hold a lot more data per tape.
We use our 9940B's in a windows only installation, but if you have a lot of
data I would look into using Solaris for the master and media servers.
I would also go for a FC only solution.
