VxRail Networking

Jump to solution

Hello,

Question related to VxRail networking:

- Can / should you create a trunk over both 10Gb ports or do we use VMware to load-balance over the two uplinks?

- Would it be best practise to put the VSAN traffic on a separate pNIC or use VLAN to separate it?

I am asking because it seems Nutanix is spreading this FUD over VSAN and I want to know how to counter it.

Thanks!

There are no trunks that you need to create.  VMware handles all the load balancing etc. 

The best practice is to use vlans to separate out various types of traffic.  VLANS for Management, VSAN, VMOTION, and VMNetowrks.

Curious - what FUD are they saying?

How many min Physical ports do we need on a TOR for 16 VxRAIL appliances....120 onwards?

For 16 Appliances you need 64  10 Gb physical ports on TOR. In case you are using  2 x 10 Gb switches for high availability , 32 Physical port on each switch are required for 16 appliances.

I would think that for 64 nodes / 16 appliances, you would need 64 x 2 ports - two 10G ports per node... so 128 ports on the switch(es).

My 2 cents.

One customer referred to the fact that we use VLAN's to separate the different networks whereas others have the option to separate on physical ports. And since VSAN requires a dedicated port, all the other networks go on the other remaining one.

I don't know if it is FUD - it is just how we do it and what software define is all about.
