granularity than a file system or a volume.
YesYesVeritas File System
YesYesMulti-Volume File System - Allows more than 1 volume to comprise a file
system. The VxFS intent log and other metadata can be placed on a
separate volume(s), and files can be dynamically striped across multiple
volumes, avoiding volume relayouts when adding storage. This does not
license Dynamic Storage Tiering lthough both share many underlying
technical components.

YesYesSmartmove (volume resynchronization)
YesYesThin Provisioning
YesYesDynamic Multipathing (DMP) - Balance I/O across multiple paths between
the server and the storage array to improve performance and availability,
