Default Difference between F1 and U1 Storage?

Hi, wonder if anyone can help me. I have just taken into stock from a
corporate clearance a large number of U1 and F1 rackmount storage arrays.
Both models look to be identical and I can't find any info on the web
regarding the difference, can anyone in here give me a quick rundown of the
difference between these two models (if any?)

F1 = Single Channel FastWide SCSI (20MB/s)
U1 = Single Channel WideUltra SCSI (40MB/s)

Thanks so does this mean the SCSI-3 modules in the F1 arrays I have will
only actually operate at 20MB/s regardless?

based on the SCSI I/O board that is in the back of that cabinet, Yes.
However, you can upgrade that controller to a U1/U2 to preserve the use of
the cabinet. The backplane is the same in both devices, and there are even
FC-AL conversion kits for them so you can run ribrechannel to them as well.

Ah so the SCSI I/O board is clearly marked SCSI-3, this is the thing that
runs along the top between the PSUs and has grey lugs (like the red ones on
the hard drives) so that it can be easily removed, right?

Am I right in thinking that these F1 arrays did not originally come with
SCSI 3 I/O boards but these ones have been upgraded and now that these
boards have been fitted they will actually support SCSI-3 if the backplanes
are the same in both models?

I would come to the same conclusion you did. Just be mindful that by SCSI-3
it is mean WideUltraSCSI-3, not Ultra3 (U160). You can put any SCA drive
into those trays and use them, but due to the I/O controller limitations you
will only ever get 40MB/s out of them.

That's great, thanks for all your help & Merry Xmas.
