Backup over SAS

Hello,

i have AIC XJ3000-3136 shared storage connected to 8 servers (over SAS switch) and now i would like to backup those servers with backup exec 12.5 . I found there is a shared storage licencse but only SAN is mentioned there. Is it possible to do backups over SAS with backup exec 12.5 (i want to avoid using network agents if possible)?

Thanks
