SAN Client backup into Netbackup Appliance 5220

Hello,

I would like to backup the clients directly on the Netbackup Appliance 5220 through FC SAN.

The client only has one FC-HBA (single port) already connected with a Storage Array.

Can I use the same FC-HBA to backup on the Appliance 5220 (I will add a dedicated backup zone).

Do I need to add a dedicated FC-HBA for each SAN-Client?

Thanks for your feedback.

Jacques
