you will need BE SAN shared storage option license.  1) you still need a regular agent too, but if you present tape drive directly to the host, data will travel over the SAN and metadata traffic will travel over IP to BE server. Essentially that server becomes a media server. 2) see #1 3) if you are doing LAN-free backup, data will not be sent to your BE server ..data will be sent directly to the tape library.  This should help  [URL]
Hi,  We are using Brocade 200 FC Switch with CLARiiON CX4 SAN.  We have installed BackupExec 2012 on a Windows Server that is zoned with FC TL2000 Tape Library at FC Switch.  There are some other servers that are connected to the SAN via FC Switch. And we get BackupExec Agent installed on those servers.  We just wonder whether the data are backed up via the SAN or still goes through the LAN ?  Although we are using vRanger for VM backup, my supervisor still installs BackupExec Agent on VMs running on ESXi 5 Host.  We use the same BE Server to backup data on those VMs (In addition to vRanger backup).  Do those data backed up via the SAN or LAN ?  If all backup data goes through the LAN, what is the benefit of using a FC Tape Library ?  Your advice is sought.  Thanks
Is our configuration a LAN Free Backup Environment ?
