before ACI, we can connect to our netapp storage, after aci project, we have DVS, and we can't access netapp anymore, we believe MTU needs to be adjusted, so should we increase MTU or decrease MTU and how much will be sufficient?
I don't think this is related to a MTU issue. Are you using iSCSI, NFS, CIFS with your NetApp storage. Which virtual switch did you use before the change to ACI ? legacy vswitch ?
I agree with Walter, it’s going to depend on what SAN protocol your using. I did know that the older leaf switches had issues with iSCSI and the buffers in the non EX and FX versions of switches, but it wouldn’t stop connectivity to your SAN switches. Also how are your EPG’s setup? Are the servers and SAN devices in the same EPG or in different EPG’s that have a contract to allow communication?
