Controlling Access at the Switch
A port binding feature is available on switches and directors that allows you to
“bind” a specific switch or director port to the WWN of an attached device for
exclusive communication. This WWN binding feature is available through the
Configure Ports option in the Product Manager application’s Configure menu.
This feature is also available through the pop-up menu when you right click a port
in the Hardware View, Port Card View, Port List View, and Performance
View.
Controlling Access at the Server or Storage Device
Features available at the server or storage device can add methods, beyond zoning,
to increase network security measures, differentiate between operating systems,
and prevent data loss or corruption by controlling access between devices or
between separate user groups (such as Engineering or Human Resources).
Server-level access control is called persistent binding. Persistent binding uses
configuration information stored on the server and is implemented through the
server’s host bus adapter (HBA) driver. The process binds a server device name to
a specific Fibre Channel storage volume or logical unit number (LUN), through a
specific HBA and storage port WWN. In essence, this feature creates a reliable
route across the fabric that sustains the small computer system interface (SCSI)
connection between a server and storage device.
For persistent binding:
■
Each server HBA is explicitly bound to a storage volume or LUN, and access
is explicitly authorized (access is blocked by default).
■
The process is compatible with open system interconnection (OSI) standards.
The following are transparently supported:
— Different operating systems and applications.
— Different storage volume managers and file systems.
— Different fabric devices, including disk drives, tape drives, and tape
libraries.
■
If the server is rebooted, the server-to-storage connection is automatically
reestablished.
