Single Fabric Interconnect

[declan.mccann1]

Hi

Is it possible to configure a UCS environment with just one FI?

I am aware that this is not a good idea and there will be redundancy considerations but I have been asked the question.

It will be in a test environment but support from Cisco would still be required.

Any opinions would be apriciated . 

Thanks

It can be done ! however, it is a very bad idea indeed. The only motivation is cost saving !

A test environment should simulate a operational environment, which I hope consists of 2 FI's. Why then do this ?

I bet 99.99% of all UCS installations are 2 FI's configurations.

Hi Walter,

Thanks for your reply.

I agree with you 100%, and yes it is purely for cost savings.

I wonder, now, if Cisco would support such a config?

Hi Declan

Open a TAC case and ask them this question.

I would think it is supported, because you are initially asked if this should become a single or clustered configuration.

Thank you all for you help.

Hello,

Yes, we will support you with one fabric interconnect, but as Walter mentioned, there is a critical lack of redundancy and we typically only see it in lab environments.

HTH,
