To provide guidance regarding supported NVMe devices in vSAN environments.

What is a tri-mode controller?

Discrete RAID controllers that support SATA/SAS/NVMe are often known as "Tri-mode controllers". 


VMware vSAN will only support SAS and SATA devices attached to a Tri-mode controller.
NVMe devices attached to Tri-mode controller are NOT a vSAN supported configuration.



Resolution

NVMe devices are only supported directly connected to a PCIe slot on the bus.
