UCS FI Cabling

Hi All,

Usually, we do the cabling of FI to IOM as following :

Left IOM to FI-A and Right IOM to FI-B (Attachment Cabling A)

Is posiible if we connect the Left IOM to FI-B and Right IOM to FI-A (Attachment Cabling B) ?

Any impact and consideration ?

Really need the detailed explanation

Thanks,

Gofi

Hi Gofi,

You can surely do this and there will be no issues or impact.

This is fully supported, as long as there is 1:1 relation between the IOM and FI i.e. one IOM goes to one FI only.

Gofi,

The explanation given by Abhinav is totally correct, there is no issue as long as each IOM goes to only one FI.  The only recommendation is that you keep that consistent in the DC, otherwise, if you have more FIs, troubleshooting will be a real pain when you have to determine who through what.

My 2 cents

Hi All,

Thanks a lot. After tried it in our lab, it seems everything gone ok while used Cabling B. The PWWN of vHBA active on FI-A was found on FI-A, and vice versa PWWN of vHBA acitve on FI-B was also found on FI-B.

I tried boot from SAN and everything gone ok like using cabling A.

Thanks a lot for the explanation

Kind Regards,

Gofi
