 A category of {{< glossary_tooltip text="devices" term_id="device" >}} in the
 cluster that can be used with dynamic resource allocation (DRA).

<!--more-->

Administrators or device owners use DeviceClasses to define a set of devices
that can be claimed and used in workloads. Devices are claimed by creating
{{< glossary_tooltip text="ResourceClaims" term_id="resourceclaim" >}}
that filter for specific device parameters in a DeviceClass.
