vNetwork Standard Switch(vSS)和vNetwork Distributed Switch(vDS)的区别

vSS: vSwitches are configured on each ESXi/ESX host.

vDS: The configuration of vDS is centralized to vCenter Server. The ESXi/ESX 4.x and ESXi 5.x hosts that belong to a dvSwitch do not need further configuration to be compliant.

 

These features are available with both types of virtual switches:

• Can forward L2 frames
• Can segment traffic into VLANs
• Can use and understand 802.1q VLAN encapsulation
• Can have more than one uplink (NIC Teaming)
• Can have traffic shaping for the outbound (TX) traffic

These features are available only with a Distributed Switch:

• Can shape inbound (RX) traffic
• Has a central unified management interface through vCenter Server
• Supports Private VLANs (PVLANs)
• Provides potential customization of Data and Control Planes
