Hello George,
We are planning to purchase this card, but we want to find ut first if it
will work on our server and tape library.
We have a Dell PowerEdge 2850 as the backup server and ADIC Scalar 100 tape
Is the LSI Logic 22320-R card/adapter compatible with the server and tape

thanks in advance,
