Which statement is true about the hardware configuration for ESXi hosts participating in a virtual SAN?

vSAN does not require identical hardware across hosts; it supports heterogeneous configurations as long as each host meets the minimum vSAN hardware requirements.

vSAN uses a disk group model in which at least one SSD is mandatory per disk group to act as the read/write cache tier. Without an SSD, the host cannot contribute storage capacity to the vSAN datastore, making this a firm hardware prerequisite for every participating host.

vSAN is a software-defined, hyperconverged storage solution that uses locally attached disks on ESXi hosts; network-attached storage is not required and is a separate storage paradigm.

vSAN supports pass-through (HBA) mode and does not require a RAID controller; in fact, VMware recommends using HBAs in pass-through mode to give vSAN direct disk control.
