Resource pools#

A Dell Data Processing Engine resource pool provides a mechanism for the platform administrator to partition the total allocated resource capacity into smaller parts. A resource pool has characteristics such as a name, the minimum and maximum number of CPU cores, and the minimum and maximum amount of memory. When the total resource allocation quota is first created, Dell Data Processing Engine assigns all of your resources to the default resource pool.

Resource pools can be managed using the resource pools management UI or programmatically with the CLI.

Resource pools UI#

The Resource pools management UI pane lets you configure and manage your Dell Data Processing engine resource pools. You must have the Spark management UI privilege to access the Resource pools management pane.

View resource pools#

The Resource pools management UI pane lists relevant information about your resource pools:
