Summary

This draft adds concrete machine-selection guidance for Google Cloud Batch Fusion Snapshots.

Source context

Doc target

  • fusion_docs/guide/snapshots/gcp.md

Rationale

The EDU ticket pointed to a documentation gap around which machine types are suitable for Fusion Snapshots on Google Batch. The existing docs already described the feature, but they did not connect snapshot reliability to local SSD support or give a practical starting point for production sizing.

Validation

  • Reviewed the edited page directly
  • Confirmed the new guidance aligns with the existing Google Batch Fusion guidance already documented elsewhere in the docs repo
  • Did not run a full docs build in the temp automation clone

Follow-up

Please sanity-check whether we want additional cross-links from compute environment docs back into the Fusion Snapshots guide.

- For production workloads, start with an `n2-highmem-16-lssd` VM or larger, then validate checkpoint duration with your workload profile.
- If your workload has larger memory footprints, increase the machine size conservatively and re-test snapshot and restore times before widening usage.

See [Google Cloud Batch compute environment configuration](../../platform-cloud/docs/compute-envs/google-cloud-batch.md#use-fusion-v2) for the underlying Fusion v2 compute recommendations that also apply to Fusion Snapshots on Google Batch.

@llewellyn-sl, this type of linking won't work in this doc because of how the repo is structured, and the anchor it's pointing to doesn't technically exist. It's a drop-down element with no link. I'll edit the page to make that a section as that would work better but we probably need rules around linking.
