SCSI Persistent Reservation (SCSI-PR) command support in disk firmware is a Microsoft failover clustering requirement. If Storage Spaces technology is being deployed in Windows failover cluster configuration then all the disk drives must implement SCSI-PR. SCSI-PR compliant firmware is available at https://support.dell.com for many disk drives shipped in the past.
See the following table for the list of Dell HDD/SSD part numbers and the minimum firmware levels that have SCSI Persistent Reservation (SCSI-PR) support.
