vCenter is a management system for vSphere environment, including a distributed virtual switch. A distributed virtual switch created in vCenter is a control plane (used for management) and hidden standard vSwitches on ESXi hosts are the IO plane (responsible for network operation).Īfter VM migration from one ESXi host to another is performed, the VM remains connected to the same port of the distributed virtual switch (also referred to as networking vMotion, which preserves the consistency in network connectivity of VMs). You only need to create a port group once, which is a significant advantage. If you create a port group for VLAN on a distributed virtual switch, the same port group will be created on all vSwitches of ESXi hosts associated to that VDS. When you create a distributed virtual switch in vCenter, identical hidden standard vSwitches are created on all ESXi hosts added to VDS configuration. A distributed virtual switch is like a template stored in vCenter. A distributed virtual switch is a logical switch that is created on vCenter Server and is applied to all ESXi hosts added to the distributed virtual switch. What Is a Distributed Virtual Switch in vSphere?Ī virtual switch, much like a physical switch, ensures the layer 2 network connectivity.

Adding ESXi Hosts to a VMware Distributed SwitchĮven if you use clusters and distributed virtual switches, remember to back up your virtual machines.VMware Distributed Switch Configuration.VDS Features Missing in a Standard vSwitch.What Is a Distributed Virtual Switch in vSphere?.This blog post consists of the following parts: Today’s blog post covers a VMware distributed virtual switch that is also called a dvSwitch or VDS. VMware takes this situation into account and develops a distributed virtual switch that can be configured on vCenter Server once without the need to configure standard vSwitches on each ESXi host manually. However, if you need to add a new port group associated to VLAN for connecting virtual machines running on ESXi hosts to that VLAN, you will need to configure vSwitch on each ESXi host identically and perform the configuration manually, which can take a long time. A standard virtual switch is a useful feature, but in large virtual environments, virtual switches on each ESXi host usually have the identical vSwitch configuration (port groups, VLANs, connected networks etc.). A vSwitch is a virtual switch provided by VMware for their virtualization solutions.
