Using only native

Expanded Data
ONTAP feature set
Chapter 1: Implementation Overview
Note
The preceding illustration shows single-path connections between the gateway
controllers and disk shelves. See Appendix B,
Multipath Storage," on page 65 for information about how to set up multipath
connections between the gateway controllers and disk shelves.
Disk shelves that meet gateway requirements can be installed on new and
existing gateways. You can add disk shelves to your gateways in any of the
following ways:
◆
Order native disk shelves with a new gateway
◆
Add a new native disk shelf to an existing gateway
◆
Move a disk shelf from an N series storage system to a gateway or between
gateways
Although typical gateways that use native disk shelves also use third-party
storage, using only native disk shelves with a gateway is supported.
A few Data ONTAP features, such as compliance features, require that Data
ONTAP have complete control over the storage. Such features are now supported
on native disk shelves used with gateways, but not with the third-party storage.
Not all features are supported with all versions of Data ONTAP. See the gateway
Interoperability Matrix to determine which features are supported with your
release of Data ONTAP.
