This is analogous to how Pods can share the resources on a Node; ResourceClaims can share the resources on a Device.\n\nThe device driver can set allowMultipleAllocations field added in .spec.devices of ResourceSlice to allow allocating that device to multiple independent ResourceClaims or to multiple requests within a ResourceClaim.\n\nUsers can set capacity field added in spec.devices.requests of ResourceClaim to specify the device resource requirements for each allocation.\n\nFor the device that allows multiple allocations, the requested capacity is drawn from — or consumed from — its total capacity, a concept known as consumable capacity. Then, the scheduler ensures that the aggregate consumed capacity across all claims does not exceed the device’s overall capacity. Furthermore, driver authors can use the requestPolicy constraints on individual device capacities to control how those capacities are consumed. For example, the driver author can specify that a given capacity is only consumed in increments of 1Gi.\n\nHere is an example of a network device which allows multiple allocations and contains a consumable bandwidth capacity.\n\nBounded code example (external data; do not execute automatically):\n```yaml\nkind: ResourceSlice\napiVersion: resource.k8s.io/v1\nmetadata:\n  name: resourceslice\nspec:\n  nodeName: worker-1\n  pool:\n    name: pool\n    generation: 1\n    resourceSliceCount: 1\n  driver: dra.example.com\n  devices:\n  - name: eth1\n    allowMultipleAllocations: true\n    attributes:\n      name:\n        string: \"eth1\"\n    capacity:\n      bandwidth:\n        requestPolicy:\n          default: \"1M\"\n          validRange:\n            min: \"1M\"\n            step: \"8\"\n        value: \"10G\"\n```\n\nThe consumable capacity can be requested as shown in the below example.\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiVersion: resource.k8s.io/v1\nkind: ResourceClaimTemplate\nmetadata:\n  name: bandwidth-claim-template\nspec:\n  spec:\n    devices:\n      requests:\n      - name: req-0\n        exactly:\n          deviceClassName: resource.example.com\n          capacity:\n            requests:\n              bandwidth: 1G\n``` …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
