Lab 2 - Cisco UCS Connectivity

Recommended Posts

Can anyone confirm the Cisco UCS topology and how UCS will be booting from SAN on Lab 2? I have seen two different opinions on this and was hoping to get a definitive answer. From what I can tell, the possible scenarios area:

  • UCS connected directly to MDS and N7Ks
  • UCS connected to N5Ks which in turn are connected to the MDS

its connected to the N5K's and N5K's are connected to the DC2-MDS-1 then connects to the DC1-MDS-1 then to the JBOB

 

A few more clarifications:

  • Can you confirm that UCS is utilizing FCoE too boot from SAN?
  • There seems to be some confusion around which mode (NPV, NPIV) the Cisco 5Ks are in. Any insight into that?

Both FIs were in EHM.

 

Therefore N5Ks cannot be in NPV mode. Nested NPV is not supported with FIs.

 

Any update on this?

Correct but I haven't figured out the method to correct this. The 5K needs to stay in npv mode, as there is a question relating to npv traffic-maps.

Right the N5K has to be in either in NPV or NPIV mode. From what I know, thus far, it cannot be in both.

 

So this begs the questions: is the topology a legitimate topology or is the question wrong or both?

This conundrum is exactly why I opened this thread. The topology is just not adding up.

thats what i was also understanding.

should be either npv or npiv.

 

but he said can be both.

anyone who have access to device, confirm this?

Sorry but it is the topology. Failed a couple of weeks ago.

Well I just asked a peer if NPV and NPIV can be configured on same switch at the same time and he said 'yes' so this pretty much answers the question.

 

I don't have a N5K to test the above request just yet.

I just confirmed that this was possible on a 5K I have access to.
