IP load balancing

IP load balancing is added to Veritas Access as a technical preview feature.

The purpose of this feature is to reduce the number of virtual IPs required for Veritas Access. With IP load balancing, a single virtual IP is used to act as a load balance IP which distributes the incoming request to the nodes.

The following functionality is available in this feature:

  • One of the existing Veritas Access virtual IP is configured as the load balancer IP.

  • All clients can connect to the Veritas Access cluster using this single virtual IP.

  • Veritas Access makes use of load balancer algorithms internally to allocate the next available Veritas Access node to serve the client.

    Currently, the Veritas Access cluster makes use of the round-robin algorithm in the implementation of the load balancer.

  • Enter the following command to configure the load balancer.

    Network> loadbalancer configure <VIP>

  • Enter the following command to destroy the load balancer configuration. 

    Network> loadbalancer remove

Note:

Only NFSv3 is supported for this technical preview.

The following limitation is present in this feature:

  • If a new virtual IP is added or a virtual IP fails over after the load balancer is set up, the load balancer configuration gets deleted. The load balancer needs to be set up again.
