Mandatory Pre-Flight Input - **Constraint**: Before querying for data or generating a report, you **MUST** ask the user which regions they plan to deploy storage in, and the desired capacity/size of storage in each region. - **Action**: Halt execution and prompt the user if regions are not provided. Do not run commands until this condition is met. ### 2. Regional Discovery - Check storage quotas in the target regions: ```bash gcloud compute regions describe <region> --format="json(quotas)" ``` - Verify the regional availability of Filestore and Managed Lustre within specified locations. ### 3. HPC Storage Quota Analysis - **Filestore Zonal**: Calculate headroom for Basic/Performance tiers (capacity in TB and instance counts). - **Filestore Regional / Enterprise**: Calculate headroom for regional tiers with high-availability requirements. - **Managed Lustre**: Calculate headroom for Lustre throughput/capacity limits and instance quotas. ### 4. Report Generation Generate a clean, Markdown-formatted summary report that includes: - Available storage types per region. - Filestore zonal quota headroom (Capacity and Instances). - Filestore basic / regional quota headroom (Capacity and Instances). - Managed Lustre quota headroom (Capacity and Instances). - **Workload Guidance**: Explain which storage tiers are best suited for the workload (e.g., Managed Lustre for high-throughput scratch space vs. Filestore for persistent home directories).
