To configure Fault Tolerance (FT) in vSphere, follow these steps:
1. Check hardware compatibility: First, ensure that your host servers have compatible processors that support FT.
1. Enable FT: FT is enabled at the virtual machine (VM) level. Right-click on the VM and select “Fault Tolerance > Turn On Fault Tolerance.”
1. Select the secondary VM: Once you enable FT, vSphere will prompt you to select a secondary VM. Select a host with sufficient resources to accommodate the secondary VM.
1. Configure network settings: Configure the network settings for the primary and secondary VMs. Each VM should have a unique IP address and MAC address.
1. Verify FT configuration: Verify that the FT configuration is correct by checking the FT status in the vSphere client.
1. Test FT: Perform a test failover to ensure that your FT configuration is functioning properly.
By configuring FT in vSphere, you can improve business continuity by ensuring that your applications and services remain available even in the event of a hardware failure. FT provides continuous protection for your VMs by creating and maintaining a replica of each VM on a separate host server.
