How many uplink did you connected from each Fabric Interconnect?

Thanks for this. We just got UCS plopped in our env and currently not using any NPIV. Any one else experience any downstream affects? Curious.

Thank Craig, that makes sense. Thanks for the reply

When you mentioned 2 UCS, let’s assume you will have total 4 UCS Fabric Interconnect 6120 in this case. If you would like to access to the same VSAN for both UCS sets, you may consider to configure same VSAN for both UCS.

This may happen when all the necessary Storage Devices require to presented to 2 UCS sets. In another situation, you may consider to build a new VSAN with VSAN routing on MDS for isolation purpose. There is no right or wrong, choose the best fit for your case.

Thanks for this article. This is the only one I could find online about the Cisco MDS and Cisco UCS uplink configuration for the Fibre Channel Network.

I have a quick question on proper configuration when zoning though. When connecting the two UCS devices to the two Cisco MDS (9100) switches should I create two separate VSANs such as VSAN10 and 11 for each individual UCS ? Or can they both go into the same VSAN ?

Sorry as I had confused with the configuration, you are right, for the SAN boot, we did include the WWPN for the storage target.

From the URL you posted, it does mean that. In all deployment we done, we did not include WWPN, so far everything is running fine. Let me verify with my counterpart from Cisco again about this and come back to you. Thanks for sharing.

according to Cisco’s recommended configurations, WWPN is the preferred method. WWNN mapping can cause issues. Review here:

in MDS you can try this command, show flogi database, or show flogi fcns database

in Clariion, I created the host group and add the necessary host to access to the specify LUN. All the host WWN will be required to be registered in Navisphere from EMC.

Craig,

Thanks very useful. I’ve been struggling with this for some time. How do you see the the WWN login: either via cli, device manger or fabric manager. Where exactly you do this? And also how do you mask it in Clarion (or any storage).
