Before you install and configure the virtual SMU, consider the following:
- A minimum amount of resources must be available for each VM if the hypervisor is configured to enforce minimum reservations. For more information, see Memory and CPU resource allocations.
- The following SMU software versions support up to 10 managed servers or clusters:
- VMware vSphere® (ESXi): Version 12.5.4038.04 or later.
- Hyper-V: Version 12.7.4221.xx or later.
Earlier SMU software versions support up to two managed servers or clusters.
- Open virtual appliance/application (OVA) is the standard distribution format of a virtual SMU OS for VMware. An OVA is a compressed archive (tarball) of Open Virtualization Format (OVF) files, including configuration and sparse disk image files.
A zip file containing a Virtual Hard Disk (VHDX) file is the standard distribution format of a virtual SMU OS for Hyper-V.
Important: Do not host the virtual SMU on the same HNAS cluster for which the SMU is providing quorum to avoid creating a circular dependency. A quorum loss could prevent access to the SMU's disk image.
