I use StorageTek FC to SCSI bridges (SN3250 usually) to connect my SCSI
libraries to my TSM servers. I have done it with both NT and Solaris
servers, and had very few issues. The main difference is ensuring you have
the FC HBA drivers loaded. The server will see the SCSI library as ... a
SCSI library.

I us the IBM SAN Data Gateway to connect my SCSI LTO drives.  Works
seamlessly with minimal setup.

I'm spec'ing a new TSM server.  To avoid having to spend a fortune on a
huge server just to get the I/O slots I need to support HV Diff SCSI, I'm
thinking of using protocol converters to reduce the number of I/O slots in
the new server.

In other words, the server would provide Fibre Channel or Gigabit E or
even LV Diff SCSi but I would connect my existing libraries via their HV
Diff SCSI interfaces, with the protocol converter in the middle.

Assuming this is technically feasible (and I know there are FC to SCSI
converters) would TSM work in such an arrangement?  What would change
relative to simply plugging in a SCSI cable into the server as I have now?

Server is "pSeries" or RS/6000; TSM is currently 4.1 but the new server
would (very soon) enter service at 5.1.

Thanks in Advance,
