I am running backups using Unitrends UEB of XenServer VMs. These are replicated to an offsite. I have a Dell Powervault TL2000 that i would like to write to or archive to for offsite backups. I have intentions of connecting to the XenServer Environment using a sas cable from the tape drive but i have no clue where to connect to. The storage device is a Dell MD3221i with two sas connectors and the server is a R730 with no sas connector. My question is that is it possible to have this connection from a TL2000 to a dell MD3221i and if so how do i connect the two devices? Does this scenario work with a hypervisor?

what is the best way to connect the tape drive in my situation?
