LAN-free data movement

LAN-free data movement shifts the movement of client data from the communications network to a storage area network (SAN). This decreases the load on the IBM® Storage Protect server.

The SAN provides a path that allows you to back up, restore, archive, and retrieve data to and from a SAN-attached storage device. Client data moves over the SAN to the storage device using the IBM Storage Protect Storage Agent. The Storage Agent must be installed on the same system as the client.

Linux operating systems Oracle Solaris operating
systems AIX operating systems AIX®, Linux®, and Solaris clients support LAN-free data movement.

Windows operating systems All Windows clients support LAN-free data movement.

Restriction: Client encryption with the include.encrypt option is no longer supported for LAN-free backup and archive operations to the IBM Storage Protect server 8.1.1 and later levels, or IBM Storage Protect7.1.8 and later version 7 levels. LAN-free restore and retrieve operations of encrypted backup versions and archive copies continue to be supported. If you need to encrypt data by using the include.encrypt option, in which data is encrypted before it is sent to the server, use LAN-based backup or archive operations.

LAN-free prerequisites

To enable LAN-free support, you must install and configure the IBM Storage Protect for SAN storage agent on the client workstation.

IBM Storage Protect for SAN is a separate product.

For more information about installing and configuring the storage agent, see the documentation for IBM Storage Protect for SAN.

LAN-free data movement options

To enable LAN-free data movement, you can use several client options. You must first install and configure the IBM Storage Protect for SAN storage agent on the client workstation.

Use the following options to enable LAN-free data movement:

enablelanfree: Specifies whether to enable an available LAN-free path to a SAN-attached storage device.
lanfreecommmethod: Specifies a communication protocol between the client and the Storage Agent.
lanfreeshmport: Specifies the unique number that is used by the client and the storage agent to identify shared memory area used for communications.
lanfreetcpport: Specifies the TCP/IP port number where the Storage Agent is listening.
lanfreetcpserveraddress: Specifies the TCP/IP address for the storage agent.
