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?) -- I.P.Freely |

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. - LC "I.P.Freely" wrote in message ...

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.P.Freely |

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. - LC "I.P.Freely" wrote in message ...
