System availability

With WebSphere eXtreme Scale, we are adding two architectural components:

We consider the availability of these components in the same way that we consider the availability of application servers in a cluster.

Configure the network as follows:

  1. Configure a minimum of three Catalog Server instances.

    These can run in the deployment manager and node agents and will add little overhead.

  2. Configure a minimum of three containers

    This ensures that the data and requests will be spread evenly even after a grid ripple-start (a ripple start stops, then starts each application server in a cluster, one at a time).

Network availability, as in other areas of the infrastructure, is critical for operation of Commerce with eXtreme Scale.
