Hi Andy, Yes, we plan to use a de-duplicating storage device for TSM.
Thanks for your responds. Do you know if the application TSM itself have preference?

File systems tend to be easier to manage. VTL option tends to cost more. Ethernet in, FC out splits the I/O across more adapters without the joy of routing tables. File systems allow you to smile and answer the auditor's question about what tape the data is on and say, "What is this tape you speak of?" The one that is better is the one that you build your system to use. I believe I could successfully argue either way. I have systems working both ways and I tend to prefer file system, but most of my Ethernet networks will not handle file system so I use mostly VTL. I should note my backend of choice is a Data Domain.
