Deploying hypervisors in a high-availability configuration

This section describes how to deploy hypervisors in a high-availability configuration.

For detailed information on configuring Edge high availability, see “Configuring Edge high availability” on page 94.

2. Ensure that the Edge is properly licensed on the active appliance and on the passive appliance.

3. Provision an NFS export (or multiple NFS exports) to host virtual machine datastores. The export(s) can be sourced from the active appliance’s local disk, or it can be sourced and mapped from a Core.

4. On both the active and the standby Edges, choose Virtualization > Installer: Installer to install the hypervisor using the Hypervisor Installer wizard. During the installation, create at least one vSwitch on each hypervisor with an uplink to a port that can reach the Virtual IP interface on the two Edges. This vSwitch must have a VMkernel port with an IP address capable of reaching the Virtual IP.

Configuring Edge high availability requires that you set up the Edge Virtual IP interface. For details, see “Configuring Edge high availability” on page 94.

Note: You must configure at least one IPv4 address. In addition, you must configure at least one IPv4 address on the hypervisor that is capable of reaching the Virtual IP on the Edge.

5. On the Core, choose Configure > NFS: Exports. For each export you created in Step 3, expand the export to modify its read/write access settings. The exports must give access to:

• the list of IPs on the stand-by Edge’s hypervisor that can reach the Virtual IP.

• the Edge’s VSP. Select the “Give VSP service on the Edge read/write access” option.

6. Mount the exports on the hypervisors as needed, and create datastores on them.

Note: If you have hypervisors in a high-availability configuration, mount the same datastores on both hypervisors. If you do not have them in an HA configuration, do not mount the same export on both hypervisors.

7. Ensure that the VMware vSphere licenses on each appliance are sufficient to enable native vSphere high availability. (Standard, Enterprise, and Enterprise Plus licenses enable high availability.)

8. Launch a vSphere Client and connect to your vCenter Server that manages the hypervisor on the Edges.

9. Using the vSphere client, place the active Edge’s hypervisor and the passive Edge’s hypervisor into the same HA cluster.
