We are in the process of designing a tape SAN that will be used for backup only using TSM on AIX and LAN-free for Solaris. We are planning on using McData 6064 directors but are going back and forth on whether to use one or two interfaces per tape drive (most likely IBM LTO or Jaguar) for redundancy and whether to ISL the directors into one fabric.Our tape fabric(s) will be completely separate from our disk fabrics. Any thoughts or rules of thumb?
