Chunklets are basic units of storage that are created automatically by HPE Storage operating systems when physical drives are added to a storage system. HPE Storage operating systems use chunklets to create logical drives, with each chunklet being assigned to only one logical drive. Chunklets are not visible to users.

Each chunklet is a unit of contiguous space on a physical drive. All chunklets are 1 GB.
