Global volumes for Serverless are in beta. Features and behavior may change before general availability.
Attaching a global volume to a Serverless endpoint gives its workers shared, region-independent access to model weights and other read-heavy data. Because a global volume has no data center, attaching one doesn’t restrict where your workers run. Your endpoint keeps access to the full GPU pool, unlike a network volume, which limits an endpoint to a single region. Global volumes are available on GPU endpoints only. CPU endpoints don’t support them. If you don’t have a global volume yet, create one first.

​
Mount path

Inside a worker, a global volume mounts at /runpod-volume, the same path used for network volumes on Serverless. Read your model files and other assets from this path in your handler function.

​
Attach a global volume to an endpoint

You attach a global volume when you create a new endpoint or edit an existing one. To attach a global volume to a new endpoint:
  1. Go to Serverless and click + New Endpoint.
  2. Configure your endpoint, then expand Advanced.
  3. Under Global volume, select the volume you want to attach.
  4. Click Deploy.
To attach or change the global volume on an existing endpoint:
  1. Go to Serverless and select your endpoint.
  2. Click Manage, then Edit Endpoint.
  3. Expand Advanced and select the global volume you want to attach.
  4. Click Save Endpoint.
Attaching a volume doesn’t copy any existing data, so upload your model files and other assets to the global volume before you attach it. Changing the attached volume triggers a new release and your workers redeploy to pick it up.
An endpoint can attach at most one global volume. It can’t use a global volume and a network volume at the same time, but it can attach multiple network volumes on their own. To switch an endpoint from network volumes to a global volume, detach the network volumes first. To switch back, remove the global volume first.

​
Limitations

  • One global volume per endpoint: An endpoint can attach at most one global volume at a time.
  • Mutually exclusive with network volumes: An endpoint can’t use a global volume and a network volume at the same time.
For shared limitations that apply to both Pods and Serverless, see Global volumes — Limitations.
