&PRODUCT; supports VMware vNetwork Distributed Switch (VDS) for virtual network configuration in a VMware vSphere environment. This section helps you configure VMware VDS in a &PRODUCT; deployment. Each vCenter server instance can support up to 128 VDS instances and each VDS instance can manage up to 500 VMware hosts.

VMware VDS is an aggregation of host-level virtual switches on a VMware vCenter server. VDS abstracts the configuration of individual virtual switches that span across a large number of hosts, and enables centralized provisioning, administration, and monitoring for your entire datacenter from a centralized interface. In effect, a VDS acts as a single virtual switch at the datacenter level and manages networking for a number of hosts in a datacenter from a centralized VMware vCenter server. Each VDS maintains network runtime state for VMs as they move across multiple hosts, enabling inline monitoring and centralized firewall services. A VDS can be deployed with or without Virtual Standard Switch and a Nexus 1000V virtual switch.

Do not attempt to configure VDS by altering VMware traffic label when configuring physical networks. This will only work for Standard Virtual Switch and should not be distributed. VMware VDS does not support multiple VDS per traffic type. If a user has many VDS switches, only one can be used for Guest traffic and another one for Public traffic. Management and Storage network does not support VDS. Therefore, use Standard Switch for these networks.

To make a &PRODUCT; deployment VDS enabled, set the vmware.use.dvswitch parameter to true by using the Global Settings page in the &PRODUCT; UI and restart the Management Server. Unless you enable the vmware.use.dvswitch parameter, you cannot see any UI options specific to VDS, and &PRODUCT; ignores the VDS-specific parameters given in the AddClusterCmd API call. Additionally, &PRODUCT; uses VDS for virtual network infrastructure if the value of vmware.use.dvswitch parameter is true and the value of vmware.use.nexus.dvswitch parameter is false. &PRODUCT; supports orchestration of virtual networks in a deployment with a mix of Virtual Distributed Switch, Standard Virtual Switch and Nexus 1000v Virtual Switch.

You can configure VDS by adding the necessary resources while a zone is created. dvSwitchConfig.png: Configuring dvSwitch Alternatively, you can create an additional cluster with VDS enabled in the existing zone. Use the Add Cluster option. For information as given in . In both these cases, you must specify the following parameters to configure VDS: Parameters Description Cluster Name Enter the name of the cluster you created in vCenter. For example, "cloud.cluster". vCenter Host Enter the name or the IP address of the vCenter host where you have deployed the VMware VDS. vCenter User name Enter the username that &PRODUCT; should use to connect to vCenter. This user must have all administrative privileges. vCenter Password Enter the password for the user named above. vCenter Datacenter Enter the vCenter datacenter that the cluster is in. For example, "cloud.dc.VM". Override Public Traffic Enable this option to override the zone-wide public traffic for the cluster you are creating. Public Traffic vSwitch Type This option is displayed only if you enable the Override Public Traffic option. Select VMware vNetwork Distributed Virtual Switch. If the vmware.use.dvswitch global parameter is true, the default option will be VMware vNetwork Distributed Virtual Switch. Public Traffic vSwitch Name Name of virtual switch to be used for the public traffic. Override Guest Traffic Enable the option to override the zone-wide guest traffic for the cluster you are creating. Guest Traffic vSwitch Type This option is displayed only if you enable the Override Guest Traffic option. Select VMware vNetwork Distributed Virtual Switch. If the vmware.use.dvswitch global parameter is true, the default option will be VMware vNetwork Distributed Virtual Switch. Guest Traffic vSwitch Name Name of virtual switch to be used for guest traffic.

In the vCenter datacenter that is served by the VDS, ensure that you delete all the hosts in the corresponding cluster. Log in with Admin permissions to the &PRODUCT; administrator UI. In the left navigation bar, select Infrastructure. In the Infrastructure page, click View all under Clusters. Select the cluster where you want to remove the virtual switch. In the VMware dvSwitch tab, click the name of the virtual switch. In the Details page, click Delete VMware dvSwitch icon.
