VSAN presents shared storage to ESXi hosts across a vSphere Cluster. Each host providing storage to the VSAN cluster requires the following:
- Solid-State Disks (SSD) to provide performance
- Hard Disk Drives (HDD) or SSDs to provide capacity
- A disk controller
- Network connectivity between hosts
As with all hardware in a vSphere environment, the hardware supporting VSAN must be verified on the Hardware Compatibility List (HCL) located at http://www.vmware.com/resources/compatibility/search.php?deviceCategory=vsan. Compatibility of the SSD, HDD, and disk controller, including the firmware, should all be validated on the HCL. Many server hardware vendors offer VSAN-ready nodes that have been preconfigured with supported hardware/firmware. ...
