Description

As a best practice, NetApp LUNs should always be partitioned with a single primary partition. The partition serves two purposes. It functions as a label for the LUN or virtual disk which helps the operating system identify the contents of the LUN or virtual disk. The partition is also used to align the host's file system with the LUN or virtual disk. Aligning the host file system is necessary to achieve optimal performance of read and write I/Os.
