NDMP Options query

Hi

I have a NetApp filer and a NetBackup server all on the same SAN. Can I attach a 4 drive library to the SAN and configure it such that I can do NDMP backups from the NetApp over the SAN directly to the library and also media manage backups through the NetBackup media server to the same library?

If this is possible would I need to allocate 2 drives for NDMP and two drives for Media Manager storage units - or could everything be shared with the SSO licence?

kind regards

K
