Implementation Overview
About this chapter
This chapter provides an overview of gateway support for native disk shelves
with IBM® N series gateways. Later chapters discuss the requirements and
procedures for setting up native disk shelves with a gateway.
Note
IBM gateway models and filers with gateway functionality are both referred to as
gateways.
Information
provided in this
guide The majority of the processes for setting up and managing disk shelves are the
same on all systems running Data ONTAP®. This book describes the differences
for gateways and provides information to help you plan for, set up, and manage a
system that uses both native disk shelves and array LUNs from third-party
storage arrays.
Note
For information about planning for and setting up array LUNs from third-party
storage array vendors with gateways, see other guides in the gateway library,
particularly the implementation guides.

Terminology
This document refers to storage from third-party storage arrays and native disk
shelves that are directly connected to the gateway. The following terminology is
used to clarify the type of storage being discussed.
array LUN:
The term array LUN is used in the gateway library to refer to the
storage that third-party storage arrays provide to the gateway. One array LUN is
the equivalent of one disk on a disk shelf connected to a gateway.
