What is a minimum disk controller requirement for VMware vSAN?
The minimum disk controller requirement for VMware vSAN is a disk controller in pass-through or RAID 0 mode. These configurations allow vSAN to directly manage the disks, providing optimal performance and reliability for the virtual storage area network. RAID 0 configuration ensures that disks are presented individually to VMware vSAN, similar to pass-through mode, which is necessary for proper vSAN functionality.
D is correct -- One SAS or SATA host bus adapter (HBA), or a RAID controller that is in passthrough mode or RAID 0 mode. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-planning.doc/GUID-4B738A10-4506-4D70-8339-28D8C8331A15.html
I don't see a clear difference between jbod and pass-through?
D is correct, you know? https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-planning.doc/GUID-4B738A10-4506-4D70-8339-28D8C8331A15.html
D is correct
vSAN Hardware Requirements These have been mentioned in earlier sections, but hardware requirements for the ESXi hosts include: Must have a cache and a capacity device Storage controllers must be able to do storage pass through or RAID 0 mode with a single disk Don’t use the same storage controller for vSAN devices and non-vSAN devices such as a boot disk You can mix and match SAS and SATA devices in a disk group – however, it is always recommended to stay uniform in storage hardware as this can lead to unexpected performance anomalies Memory requirements vary depending on the number of disk groups and devices the ESXi host has to manage
