Failover considerations

The Grid takes care of distributing the nodes of a grid application over the available hosts for that application. The bindings of each node define how many instances of the node are expected to run. When one of the hosts fails in a multiple hosts setup for the Infor ION Grid assigned to for example the IONService application, the Grid ensures that nodes that were running on that host automatically are started on another host. Downtime will be limited for the time the grid identifies the failure and start time of the (ION) nodes. If you like to have a predefined distribution of the nodes over the hosts, you can make use of the ‘preferred host’ option on the Grid binding to have a default distribution while remaining to have the full fail-over capabilities.

Failover of Grid components See "Disaster Recovery" in the Infor ION Grid Administration Guide .

Infor ION Grid scaling considerations

You can scale out by adding hosts to the Infor LTR deployment. The Infor ION Grid takes care of distributing the nodes of the applications over the available hosts for these applications.

Scaling is used for both availability and performance reasons. Use the grid counters to verify if your current deployment is reaching the limits of the system resources.

For details, see "Monitoring the Grid" in the Infor ION Grid Administration Guide.
