Data ONTAP supports using the same disks behind the storage arrays that the vendor supports (that is, disks external to the storage array). Data ONTAP assumes that the configuration between the storage array and the external disks behind it is correct.
In the case of external disks, the paths go from the V-Series system through the storage array to the external disks. See the V-Series Installation Requirements and Reference Guide for information about the number of paths supported for different Data ONTAP releases and modes.
