This article provides information on the use of AHCI controllers in vSAN nodes.


VMware vSAN 6.x


The use of AHCI controllers to connect vSAN drives is not supported. SAS/SATA SSDs are supported only in the scenario where they are connected to a SAS/SATA HBA or RAID controller. Refer to the vSAN VCG for a list of supported RAID and HBA devices.
AHCI controllers may be used to connect boot drives for a vSAN node, as long as the boot device meets the endurance and performance criteria for ESXi boot. For more information, see M.2 SSD as Boot Device for vSAN.
