As the demands on datacenters continue to grow and accelerate, requirements related to speed and access to the data itself continue to grow as well. In most infrastructures, virtual machine access and mobility usually depend on physical networking infrastructure and the physical networking environments they reside in. This can force virtual workloads into less than ideal environments due to potential layer 2 or layer 3 boundaries, such as being tied to specific VLAN's.

Network virtualization allows you to place these virtual workloads on any available infrastructure in the datacenter regardless of the underlying physical network infrastructure. This not only allows increased flexibility and mobility, but increased availability and resilience.

You install the network infrastructure components in your virtual environment on a per-cluster level for each vCenter server, which deploys the required software on all hosts in the cluster. When a new host is added to this cluster, the required software is automatically installed on the newly added host. After the network infrastructure is installed on a cluster, Logical Firewall is enabled on that cluster.


Log in to the vSphere Web Client.


Click Networking & Security and then click Installation.


Click the Host Preparation tab.


For each cluster, select Install in the Installation Status column.


Monitor the installation until the Installation Status column displays a green check mark. If the Installation Status column displays a red warning icon and says Not Ready, click Resolve. Clicking Resolve might result in a reboot of the host. If the installation is still not successful, click the warning icon. All errors are displayed. Take the required action and click Resolve again.

When the installation is complete, the Installation Status column displays 6.0 and the Firewall column displays Enabled. Both columns have a green check mark as well.
