VMs and vSwitch load balancing

Hello,
While adding more VMs in my VMware Esxi 6.0 network, what it would be the practice:  should I create extra vSwitch for the new VMs connected to different NICs or I can still use the same vSwith for all VMs network but adding more NICs for load balancing ?

thank you

Best Practice, is to use a dedicated vSwitch, connected to, two or more physical uplinks (nics in the host), with a teaming policy.

for all VMs.

add more nics, if you require more bandwidth.

it's common to have a vSwitch just for the purpose of VM traffic, with at least 4 nics (if they are 1GBe)

see this example

Is this valid also for VM (ftp server) connected to a DMZ network? Should this VM_DMZ be in a separate vSwitch linked to the DMZ_network or it can be in the same vSwitch as the internal VMs but  use a separate NIC (vmin6 - see pic).

Usually your DMZ nics, would be connected directly to the DMZ. (rememeber here traffic goes across he vSwitch between VMs, and not via host nics!)

So separate vSwitch for DMZ, separate vSwitch for VMs, unless using VLANS and trunks.
