Chapter 22. Configuring node agent load concurrency

Procedure

1. If you want to use load concurrency for specific nodes, add labels to those nodes:

   $ oc label node/<node_name> label.io/instance-type='large'

   Copy to Clipboard Toggle word wrap

2. Configure the load concurrency fields for your DPA instance:

     configuration:
       nodeAgent:
         enable: true
         uploaderType: kopia
         loadConcurrency:
           globalConfig: 1
           perNodeConfig:
           - nodeSelector:
                 matchLabels:
                    label.io/instance-type: large
             number: 3

   Copy to Clipboard Toggle word wrap

   where:

   globalConfig

   Specifies the global concurrent number. The default value is 1, which means there is no concurrency and only one load is allowed. The globalConfig value does not have a limit.

   label.io/instance-type

   Specifies the label for per-node concurrency.

   number

   Specifies the per-node concurrent number. You can specify many per-node concurrent numbers, for example, based on the instance type and size. The range of per-node concurrent number is the same as the global concurrent number. If the configuration file contains a per-node concurrent number and a global concurrent number, the per-node concurrent number takes precedence.
