configure to backup data in san

I am setting Symantec Backup Exec 2010R3.

My BackupServer is connecting SAN and Ethernet. Backup Server is Physical server , not Virtual server.
and FileServer is running on the VMware(as a virtual server ) and the vmdk and FileServer's data are stored on the SAN storage.

I want to backup Fileserver's data via SAN.

How can I configure Backup exec job ?
If I make Backup exec job to backup , by default backup exec backup via SAN without any specific checking option ?
please let me know how to configure Backup via SAN ?
