Follow these guidelines when you use vSphere High Availability (HA) or Fault Tolerance (FT) to make sure that the system operates correctly.
- Verify that VMware Tools® is installed.
- Test that VMware vSphere® vMotion®, HA, or FT configurations are robust and operate correctly.
- To avoid creating a circular dependency, do not host VSP One File on the same file cluster for which VSP One File is providing quorum. A quorum loss could prevent access to the VSP One File disk image.
- Follow guidelines for CPU and memory allocations. Make sure that the VSP One File VM always has sufficient resources so that the quorum device is not paused or unresponsive for more than 5 seconds.
- Use 10 Gbps for the FT logging network. If you use less than 10 Gbps for the FT logging network, it negatively affects on the VSP One File performance.
- Use a larger ESXi license when required rather than limit the number of virtual CPUs. FT configurations allow a maximum of two or four virtual CPUs, depending on the ESXi license installed. If you have more than two or four managed entities, verify that operation is efficient with fewer than one virtual CPU per managed entity.
- Set up HA or FT configurations with the vSphere Web Client to receive error messages with more details.
