When creating the Dynamic vNIC Connection Policy I note the option “Protection” in which you can preference FabA or FabB, however, this is for the entire DVS, correct?
If I want for example a VMotion Port-Profile with ALL traffic switched locally on FabA with failover to FabB, how can this be achieved? Can Pin Groups still be used with VMFEX??
I recommend placing vMotion and Management vmkernel interfaces on standard a vSwitch and use the VM-FEX for VM networking only. VM-FEX and Nexus 1000v are really designed as VM networking access switches and not physical host access switches.
Our standard config for UCS is this:
If IP storage is in the mix then we create 2 additional vmnics for that using the Platinum class
Thanks for the response Jeremy.... Makes perfect sense, I had been told that you could not mix VMFEX with standard VMware switches (I did doubt this as I have used this mixture with none UCS + 1000v configs in the past)...
A few questions if you don’t mind:
1. In your config are you using fabric failover with the vmnics? – If so could you use 1 vmnic with each vswitch (suppressing the error from ESX re mgmt redundancy)
2. Would vmnics4/5 be added to the VMFEX DVS once the DVS has been configured and sent down to vCentre?
3. Are you applying QoS to the VMFEX Port-Profiles for standard VM networking?
4. I have read (somewhere!) that the uplinks on the VMFEX DVS are cosmetic and are not actually used to forward traffic, but more to keep vcentre happy... Not sure if this is true, however, it would also make sense. If this is the case then in the VMFEX world QoS on the uplink vmnics would have no affect and hence applying QoS to the VMFEX Port-Profiles for VM networking??? – Can you clarify this for me?
## Please note, the reason I am looking to use VMFEX is to allow the use of PVLANs on a common backup LAN ###
Lastly, I enjoyed the UCS TrainSignal stuff, very good indeed...
Yes, you can have an ESXi host with some NICs on a standard vSwitch and some on DVS.
So with VMFEX (none high perf mode) are the uplinks on the FEX DVS cosmetic? IE. VM traffic does not pass these uplinks and instead go direct to the FIs?
