For 5 TB I would suggest you connect library directly to 
your SGI box. I just not sure on how LTO tape drives will 
behave with SGI. 

Tape device driver has been an issue with SGI for a while.   
I could trace it back to 94 just discussing my problem with 
my manager, back that days he was doing my job. 

It took me well over 2 months to get answer from SGI if 
any __SAN__ configuration is supported/tested. Eventually 
I've got answer __NO__ scsi<->fc bridge was ever tested.
