Enabling T10 PI funtionality between the storage controller and disk drives helps to ensure data integrity at the drive level. T10 PI requires the use of PI capable 520 Bytes per Sector formatted disk drives. T10 PI capable drives can be used with or without the T10 PI function enabled and can be intermixed within a storage enclosure or across storage systems with non-PI formatted drives.
