While VMware supports building your own vSAN cluster from compatible components, vSAN ReadyNodes are selected for this VMware Validated Design.

Build Your Own
Use hardware from the VMware Compatibility Guide for the following vSAN components:
  • Solid state disks (SSDs)
  • Magnetic hard drives (HDDs)
  • I/O controllers, including vSAN certified driver and firmware combinations 
Use VMware vSAN ReadyNodes

A vSAN ReadyNode is a server configuration that is validated in a tested, certified hardware form factor for vSAN deployment, jointly recommended by the server OEM and VMware. See the vSAN ReadyNode documentation. The vSAN ReadyNode documentation provides examples of standardized configurations, including supported numbers of VMs and estimated number of 4K IOPS delivered.

According to design decision SDDC-PHY-009, this design uses vSAN ReadyNodes.
