Issues with 57180 connected to Cisco 93180YC-FX
I have have one M1000e chassis connected to two Cisco 5548's using the B22 FEX modules. All the blades are using NPAR with FCOE for storage connectivity. The chassis has 7 M630's with Emulex OCE 14000 adapters and 3 M640's with 57810 adapters.
Everything worked fine connected to the Cisco 5548's but ours are near end of life. We moved them to the new Cisco 93180YC-FX switces.
The M630's/Emulex servers work fine.
The 3 M640's 57810 servers have high latency to the storage and eventually the switch will disable the ports with a dcxNoAck state.
The 3 M640s are ESXi 7.0u3 w/ latest Dell firmware, ESXi 6.5 with 2 year old firmware, and RedHat Linux with 2 year old firmware. Since I have a mix of OS's and firmware, I don't think it is a firmware/driver issue since all three do the same thing. It is likely a switch setting or HBA setting but there are not that many settings on the HBA.
To sum it it, we moved from a Cisco 5548 to 93180 and now the M640/57810's don't work. Any ideas what could cause this behavior?

Hi, thanks for your question but I'm afraid this would be better addressed by Cisco. Sorry I can't be of help this time. Maybe we could wait around to see what other users could offer. Wish you a good one.

We actually have been working with Cisco and still have an open case on it but unfortunately they have not yet been able to find a cause and resolution.
