The short cable that runs down to the patch panel (barrels) on the fibre channel drives are 50 micron provided by IBM. This means that the jumper to the switch will change if you use 62.5 micron cables.
I have successfully done this, but it is not a supported configuration. Apparently, if you only do this change once in the connection it is not likely to cause a problem on short distances like you are talking about. What we have done is placed our ES-1000s under the library (3494) and cabled the drives directly into the ES-1000. Then, the uplink can be whatever you desire. You could do the same with a Brocade switch. -----Original Message----- From: Gill, Geoffrey L. [mailto:[EMAIL PROTECTED]] Sent: Monday, November 26, 2001 3:12 PM To: [EMAIL PROTECTED] Subject: 3590 Fiber drives Can anyone tell me if there are any issues with the 50 micron cables as opposed to the 62.5 micron cables and 3590 drives. Taking into consideration these will be on a SAN soon but for now direct connect. We only need to run about 50 ft between computer and drives.
