# Which pod holds which GPU?

One view, from node and pod, with Lens DRA.

![Device ledger diagram. On the left, two nodes publish Resource Slices with their driver and pool, one with 8 devices of which 6 are allocated, one with 6 MIG devices of which 1 is allocated. The middle column lists each device and who holds it: h100-0 and h100-1 held by llm-training, h100-4 by rerank-api, h100-7 flagged unhealthy as reported by the driver, mig-a0 held by notebook-ana and mig-b1 free, each with its model and capacity. On the right, the ResourceClaim that named the device class, and the pod that shows the claims and devices it holds](https://lenshq.io/images/use-cases/dra-devices.svg)

How Lens resolves it

## GPU-aware, and not only GPU

DRA reached general availability in Kubernetes 1.34. It covers any specialized device a cluster hands out through a driver: GPUs, TPUs, FPGAs, fast NICs.

![Four steps left to right: a driver reports what hardware exists as a ResourceSlice, a rule groups matching devices into a DeviceClass, a pod's ResourceClaim names one class and how many devices it needs, and Kubernetes matches a device from that class and hands it to the workload](https://lenshq.io/blog/lens-release-september26/dra-object-flow-diagram.webp)

### From the node: what it has

Its device inventory, read from the Resource Slices it publishes.

### From the pod: what it holds

The claims it holds and the devices behind them.

### Warned before the job dies

Unhealthy devices flagged as the driver reports them.

In the navigator

## Claims, templates, classes and slices

![The Device Resources navigator group in Lens K8S IDE with a Resource Claims list open for a cluster with GPU claims](https://lenshq.io/blog/lens-release-september26/device-resources-claims-view.webp)
