Dynamic Binding in distributed vSwitch is depreciated in vSphere 5.0

As of vSphere 5.0 the dynamic binding option in dvSwitch port groups earned the "Depreciated Status"
Why..??
I am not really sure...:)

VMware recommends using Static Binding for performance gain:

But as described in the KB 1010593 and KB 1022312 the only difference is in the way the ports are assigned to VMs. With static binding the port are assigned "once and forever" until removal from inventory or changing port group. With dynamic binding port are assigned every time during powering up.

Personally I haven't noticed any performance issues with the dynamic ports. However it is strongly recommend to change it - so its time to plan some downtime...:)

Once caveat -> all VMs with particular Port Group must be powered off to change its binding type...:)
