Connecting 2 servers to a single tape drive

I have 2 servers running BUExec 12.5, each one taking care of our Exchange 2007 systems. OneExchange server takes care of A-m, the other takes care of N-Z.
I have one PV124T with dual magazines.
Both media servers have dual channel Adaptec 39160 SCSI cards with dual connectors I can connect to.
I know that each tape drive must be connected to the local media server.
 However, the 124T has only 1 tape drive, and 2 SCSI connectors, one of which is using the SCSI terminator.
Is there a way that I can connect both of these media servers to the same tape drive so that I can run my tape backups after I run my incremental and full Exchange jobs? Would cross-connecting the servers do what I need to do?

Thanks in advance for any suggestiuons.

Unfortunately you cant do that as the SCSI tape device needs to hava one to one relationship with the controller so two controllers trying to talk to it together would be a recipe for disaster.

The way around this is to have a fibre attched library and to use the SAN Shared Storage Option (SSO) to allow multiple servers to "share" the library. However fibre attach adds around $4K to the library, the SSO is approx $700 per server (on top of BE itself and any other Exchange aganets etc) and youd have to have fibre HBAs ($1000 per server) and a fibre switch $2000

AFAIK you cant use SSO on a standalone drive with two connections as you outline above
