Implement a VSAN solution 100% free

To take benefit of the software-defined storage solution also for businesses with no budget, a free VSAN solution can be implemented using the available free versions of both StarWind VSAN and ESXi.

Of course this solution presents some limits but it works like a charm and allows small environments to have a reliable storage solution in place.

The components used in free-mode have the following restrictions:

StarWind VSAN free

  • VSAN can use a maxium of three nodes
  • Management through command line only, no GUI available
  • Windows-based VMs only can be used (paid version includes also VMs Linux-based)
  • No StarWind support

VMware ESXi free

  • Max 8 vCPU per each VM
  • Cannot be managed with vCenter
  • vStorage API is not available
  • No VMware support

The real limit of this free solution lies in the unavailability of the vStorage API that doesn't allow to perform VM backups at the host level, but only legacy backups (with the use of an agent) can be processed.

Fortunately agent-based solutions used to backup physical environments are widely available from vendors well known for their virtual environement backup solutions, such as Veeam, Nakivo, or Vembu just to mention some.

StarWind VSAN for vSphere is available to download as 30-day trial.
