FSx for Lustre

FSx for Lustre provides a high-performance parallel file system designed for compute-intensive workloads. It's ideal for machine learning, high-performance computing (HPC), video processing, and financial modeling.

Deployment Types

S3 Integration

FSx for Lustre can be linked to an S3 bucket as a data repository, enabling seamless access to S3 objects as files:

Data Repository Association Features:

• Lazy Loading: Files are loaded from S3 on first access
• Batch Import: Bulk import files from S3 to FSx
• Automatic Export: Changes automatically written back to S3
• S3 Event Notifications: Trigger import when S3 objects change

```bash
aws fsx create-file-system \
    --file-system-type LUSTRE \
    --storage-capacity 1200 \
    --subnet-ids subnet-12345678 \
    --lustre-configuration '{
        "DeploymentType": "PERSISTENT_2",
        "DataRepositoryConfiguration": {
            "ImportPath": "s3://my-bucket/dataset",
            "ExportPath": "s3://my-bucket/output",
            "AutoImportPolicy": "NEW_CHANGED"
        },
        "PerUnitStorageThroughput": 125
    }'
```

FSx for NetApp ONTAP

FSx for NetApp ONTAP provides fully managed shared storage built on NetApp's popular ONTAP file system. It supports NFS, SMB, and iSCSI protocols, making it ideal for multi-protocol environments.
