Re: [Networker] R: [Networker] Red Hat Adaptec driver

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
library.
Is the LSI Logic 22320-R card/adapter compatible with the server and tape
library?

thanks in advance,
Librado
