NOTICE:
Before enabling Access Control, ensure that no hosts are attempting to access the storage. Enabling
Access Control prevents all hosts from accessing any data until they are given explicit access to a LUN in the
appropriate storage group. You must stop all I/O before enabling Access Control. Dell recommends powering off all
hosts connected to the storage system during this procedure or data loss may occur. After you enable Access
Control, it cannot be disabled.
8. Click Yes to enable Access Control.
9. Right-click the icon of your storage system and select Create Storage Group.
The Create Storage Group dialog box appears.
10. In the Storage Group Name field, enter a name for the storage group.
11. In the Sharing State drop-down menu, select one of the following:
Shareable — If the storage group is for a cluster
Dedicated — If the storage group is for a nonclustered server
12. Click Apply.
13. Add new LUNs to the storage group.
a. Right-click the icon of your storage group and select Properties.
b. Click the LUNs tab.
c. In the Available LUNs window, click an available LUN.

Implementing Zoning on a Fibre Channel Switched Fabric
A Fibre Channel switched fabric consists of one or more Fibre Channel switches that provide high-speed connections between
servers and storage devices. The switches in a Fibre Channel fabric provide a connection through inbound and outbound
points from one device (sender) to another device or switch (receiver) on the network. If the data is sent to another switch,
the process repeats itself until a connection is established between the sender and the receiver.
Fibre Channel switches provide you with the ability to set up barriers between different devices and operating environments.
These barriers create logical fabric subsets with minimal software and hardware intervention. Similar to subnets in the
client/server network, logical fabric subsets divide a fabric into similar groups of components, regardless of their proximity to
one another. The logical subsets that form these barriers are called zones.
Zoning automatically and transparently enforces access of information to the zone devices. More than one NAS cluster
configuration can share a Dell | EMC SAN in a switched fabric using Fibre Channel switch zoning and Access Logix. By using
Fibre Channel switches to implement zoning, you can segment the SANs to isolate heterogeneous servers and storage
systems from each other.
