DESCRIPTION
Use this option to manage the WAN Optimization settings.
The WAN Optimization feature uses various techniques for increasing data-transfer efficiencies across wide-area networks. As a result, using WAN optimization can improve inbound and outbound data transfers to and from your appliance.
This feature includes the following benefits:
Improves NetBackup Auto Image Replication performance.
NetBackup Auto Image Replication is a disaster recovery solution. Its purpose is to create off-site copies of mission critical backups to protect against site loss.
For example, the backups that are generated in one NetBackup domain can be replicated to storage in other NetBackup domains. These other NetBackup domains may be located in diverse geographical locations. Because WAN optimization can improve wide area network data throughput to and from your appliance, more efficient backup data transfers and disaster recovery transfers can occur.
Benefits appliances for which data is sent across slower networks. For example, such as networks with a latency greater than 20 milliseconds and packet loss rates greater than 0.01% (1 in 10,0000).
Operates on individual TCP connections. Evaluates each inbound and outbound network connection to determine whether the performance can be improved.
Improves the network performance with minimal dependency on the outbound network traffic.
Improves the network performance of optimized duplications.
Improves the network performance of restores to remote clients.
Imposes no network overhead. WAN optimization is non-intrusive, as it does not impose any network overhead in situations where the overall network data transfers are high. In some scenarios, when the overall network data transfer is high, the connection speed may not be optimized despite this feature being enabled.
Note:
If you run a factory reset of the appliance, note the following:
A factory reset disables WAN optimization for all network interface bonds if you retain your network configuration. After the factory reset completes, you can then enable WAN optimization again for the network interface bonds.
If you do not retain your network configuration, all network interface bonds are lost during the factory reset. After the reset completes, the appliance automatically enables WAN optimization for all network interface ports, including those that comprised the bonds.
OPTIONS
- Enable ALL
Enable WAN optimization for all appliance network interface ports and NIC bonds at the same time.
You can also optimize NIC bonds with this command. Bonds consist of two or more NIC/eth ports that have been teamed together to form a logical network port. The logical network port is called a bond.
Note:
When configuring multiple network interfaces as a NIC bond, use the Network > LinkAggregation from the shell menu to comprise the bond. NIC bonds that are configured with tools other than the above mentioned appliance tools appear as Disabled when you run the WAN optimization Status command.
The following example shows how to use the Enable ALL command:
myappliance1.WANOptimization> Enable ALL (provided the ports are not part of a bond)
- Enable interfaceList
Enable WAN optimization for selected network interface (NIC/eth) ports on the appliance.
interfaceList specifies the selected NIC ports or NIC bonds.
Note:
Individual NIC ports cannot be optimized for WAN communications if they are teamed in a NIC bond. When you enable WAN optimization for a bond, WAN optimization is applied to each NIC port in the bond.
The following are examples of how to use the Enable command and its parameters:
myappliance1.WANOptimization> Enable eth2 (provided the port is not part of a bond)
myappliance1.WANOptimization> Enable bond0
myappliance1.WANOptimization> Enable eth0,eth1 (provided the ports are not part of a bond)
myappliance1.WANOptimization> Enable bond1,bond2
myappliance1.WANOptimization> Enable eth0,bond1 (provided the port is not part of a bond)
- Disable ALL
Disable WAN optimization for all appliance network interface ports and NIC bonds at the same time.
The following example shows how to use the Disable ALL command:
myappliance1.WANOptimization> Disable ALL
- Disable interfaceList
Disable WAN optimization for selected network interface (NIC/eth) ports on the appliance.
You can also disable WAN optimization for NIC bonds with this command. Bonds consist of two or more physical NIC/eth ports that have been teamed together to form a logical network port. The logical network port is called a bond.
interfaceList specifies the selected NIC ports or NIC bonds.
Note:
interfaceList lets you disable WAN optimization for selected NIC ports or NIC bonds, unless the selected port has been teamed together with another port to form a bond. To disable WAN optimization for the ports within the bond, you must specify the bond name when you run the Disable command.
The following are examples of how to use the Disable command and its parameters:
myappliance1.WANOptimization> Disable eth2 (provided the port is not part of a bond)
myappliance1.WANOptimization> Disable bond0
myappliance1.WANOptimization> Disable eth0,eth1 (provided the ports are not part of a bond)
myappliance1.WANOptimization> Disable bond1,bond2
myappliance1.WANOptimization> Disable eth0,bond1 (provided the port is not part of a bond)
Note:
When you disable WAN optimization for a bond, WAN optimization is disabled for each port within the bond.
- WANOptimization > Status
Shows the current WAN optimization status.
The appliance displays the optimization status in a table that resembles the following example:
