Backup Exec 2012 with server clusters supporting Backup in Tape Library

Hi folks,

I have a doubt in the Backup Exec 2012 with server clusters and  supporting Backup in Tape Library.

Testing Environment: We have  2 Cisco servers installed with Windows server 2008 R2  enabled  with microsft windows cluster (with a Quarum Disk of 5GB)  and planning to install Backup Exec 2012 with server cluster configuration and  to take backup and storing it in the  Tape Library.

please check on the below topology and clarify me how to configure this and whether this topolgy is recommended.
