Hi People,

Can anyone here please share me the best use case to use Distributed Virtual Switch compare to just using normal vSwitch for all of the ESXi hosts in a HP Blade enclosure ?

The VCenter server is a virtual machine within one ofthe ESXi 5.1u1 blades.

1. Distributed switch is easier to manage, if you got huge number of ESXi hosts.
2. Distributed switch requires some effort to design and implement.

1. Standard switch is easier to setup, whereas it becomes difficult to maintain the configuration, if your infra is large!

GG,

Ah so in this case the dvSwitch configuration is replicated or managed by VCenter so that if I have to add one VLAN / network label in one of the ESXi hosts, it will be then replicated to all of the ESXi hosts ?
