Amazon EFS can be backed by FSx for Lustre when used together, especially in scenarios where you need to leverage the high-performance capabilities of FSx for Lustre while using EFS for more general-purpose file storage. Here’s how this works:
How It Works:
- EFS to FSx for Lustre Integration:
- When you set up Amazon FSx for Lustre, you can link it to an existing Amazon EFS file system.
- The idea is that FSx for Lustre can cache the data stored in EFS for high-performance workloads. This means you can read and write data stored in EFS via the FSx for Lustre file system, benefiting from Lustre’s high-speed data processing, while keeping EFS as your persistent storage layer.
- Why Use This Integration:
- FSx for Lustre is a high-performance file system designed for workloads requiring fast processing speeds, such as machine learning, high-performance computing (HPC), and big data analytics.
- EFS is designed for scalable, shared file storage, but is not optimized for workloads requiring ultra-high throughput and low latency.
- This integration allows you to accelerate data access and processing using FSx for Lustre while maintaining EFS as the durable, persistent backend storage.
Example Use Case:
- You can link an FSx for Lustre file system to an EFS file system so that frequently accessed data from EFS is cached in FSx for Lustre for faster access.
- This allows you to process large amounts of data with low latency and high throughput while using EFS for storage of all the data.
Benefits:
- Performance Boost: By linking FSx for Lustre to EFS, you get the high-performance cache of Lustre, which boosts performance for workloads like analytics or simulations, while EFS acts as the backing storage.
- Cost-Effective: FSx for Lustre can automatically sync with EFS, meaning you’re only accessing the high-performance storage when needed, and relying on EFS for long-term, less frequently accessed data storage.
Key Points:
- This integration is available only with FSx for Lustre, not other FSx file systems like FSx for Windows File Server or FSx for OpenZFS.
- EFS and FSx for Lustre are used in a complementary way, where FSx for Lustre can cache and accelerate access to the data in EFS for performance-sensitive workloads.
