connected to a computer network providing data access to
network clients.
NDMP Network Data Management Protocol is a protocol meant to
transport data between NAS devices, also known as filers, and
backup devices. This removes the need for transporting the data
through the backup server itself, thus enhancing speed and
removing load from the backup server.

Truncation As long as free disk space is available, the DXi4500 retains
native format data on disk to provide accelerated reads from
cache. As disk space is required, the native format data is
truncated and reads come from the data deduplication
blockpool.
