How to throttle VA replication traffic within your ESX/ESXi environment
vRanger will try to use as much available network bandwidth as possible to perform the replication. This can pose a problem if network bandwidth is limited (for example: asynchronous WAN connections).
Configure ESX/ESXi
Note: This needs to be done on both the source and target ESX/ESXi servers
1. In the vSphere client, select the ESX/ESXi host that hosts the Virtual Appliance (VA)
2. Select the Configuration tab
3. Under Hardware, click the Networking link
4. Find the vswitch on where the VA connects and choose Properties
5. Click the Add... button to create a new Network Configuration
a. Connection Type: Virtual Machine
b. Network Label: <any name you choose>
6. In the vSwitch properties, select the newly created Network Configuration and click the Edit button
a. Click on the Traffic Shaping tab
b. Enable the Policy Exceptions Status
c. Change the Average Bandwidth and Peak Bandwidth settings (default setting is 100000Kbits/s or about 10MB/s)
Configure Virtual Appliances
Once the new Network configurations have been setup, change the VAs to use that Network
1. In the vSphere client, select the VA and choose Edit Settings
2. Select the Network Adapter and change the Network Connection to the newly created Network Configuration
CAVEATS:
1. If you use the VA for backup, this will also affect backup throughput
2. The traffic shaping changes only affect outgoing traffic, it does not affect incoming traffic (per VMware)
3. vRanger does not support multiple VAs on the same ESX/ESXi server
