NAS controller
Dell server preconfigured with file sharing software
(for example, FS7500 Controller).
NAS file system
Virtualized file system that consumes space in the
NAS reserve. Administrators can create CIFS shares
and NFS exports on a NAS file system and share
them with authorized users. A NAS service supports
multiple NAS file systems.
NAS node

storing internal data and user data and configured with
DSFS.
NAS service

EqualLogic FS7500, configured and managed through
Group Manager.
NAS service IP address
Highly available IP address that clients use to access
CIFS shares and NFS exports hosted by a NAS
service.
NAS service management IP address
IP address used for internal operations between NAS
nodes and the PS Series group.
node pair
Two NAS nodes that are configured as peer nodes in
a NAS service. Cache data is mirrored across the
NAS nodes.
peer node
NAS node with which a NAS node is paired in a NAS
service.
power module
One of two battery units in an FS7500 Backup Power
Supply.
