General

Q: What is Amazon FSx for Lustre?

A: Amazon FSx for Lustre provides a high-performance file system optimized for fast processing of workloads such as machine learning, high performance computing (HPC), video processing, financial modeling, and electronic design automation (EDA). These workloads commonly require data to be presented via a fast and scalable file system interface, and typically have data sets stored on long-term data stores like Amazon S3.

Operating high-performance file systems typically requires specialized expertise and administrative overhead, requiring you to provision storage servers and tune complex performance parameters. With Amazon FSx, you can launch and run a file system that provides sub-millisecond access to your data and allows you to read and write data at speeds of up to hundreds of gigabytes per second of throughput and millions of IOPS.

Amazon FSx for Lustre works natively with Amazon S3, making it easy for you process cloud data sets with high performance file systems. When linked to an S3 bucket, an FSx for Lustre file system transparently presents S3 objects as files and allows you to write results back to S3. You can also use FSx for Lustre as a standalone high-performance file system to burst your workloads from on-premises to the cloud. By copying on-premises data to an FSx for Lustre file system, you can make that data available for fast processing by compute instances running on AWS. With Amazon FSx, you pay for only the resources you use. There are no minimum commitments, upfront hardware or software costs, or additional fees.

Q: How do I access an FSx for Lustre file system from a compute instance?

A: You can access your file system from your compute instances using the open-source Lustre client. Once mounted, you can work with the files and directories in your file system just like you would with a local file system. See the FSx for Lustre documentation for details. 

Q: How do I manage an FSx for Lustre file system?

A: Amazon FSx is a fully managed service, so all of the file storage infrastructure is managed for you. When you use Amazon FSx, you avoid the complexity of deploying and maintaining complex file system infrastructure.

You can administer a file system via the AWS Management Console, the AWS command-line interface (CLI), or the Amazon FSx API (and various language-specific SDKs). The Console, API, and SDK provide the ability to create and delete file systems, create and edit file system tags, and display detailed information about file systems. If you link your filesystem to an S3 data lake, your objects will appear as files and directories as soon as your system is available.

Q: How does Amazon FS for Lustre work with long-term data repositories?

A: Amazon FSx for Lustre allows you to ingest and process large volumes of file data in a high-performance file system, while periodically writing intermediate results to your data repository. Doing so allows you to restart your workload at any time from the latest data you’ve stored in your data repository. When your workload is done, you can write final results from your file system to your data repository, and delete your file system.

Q: If I have data in S3, how do I access it from Amazon FSx for Lustre to process it?

A: If you have data in S3, you can seamlessly link your Amazon FSx for Lustre file system with a specified S3 bucket, making the data in your Amazon S3 data repository accessible to your file system. Once your file system is created, initially the S3 objects’ names and prefixes will be visible as files and directories.

By default, Amazon S3 objects are only loaded into the file system when first accessed by your applications. If your applications access objects that haven’t yet been loaded into your file system, Amazon FSx for Lustre automatically loads the corresponding objects from Amazon S3. Subsequent reads of these files are served directly out of the file system with low, consistent latencies. You can optionally batch hydrate your Amazon FSx for Lustre file system.

Amazon FSx for Lustre uses parallel data transfer techniques to transfer data from S3 at up to hundreds of GBs/s.

Q: How do I commit data written to my Amazon FSx for Lustre file system back to Amazon S3?

A: At any time, you can commit intermediate results you’ve written to your file system back to your Amazon S3 bucket. Only objects that have changed since import from S3 or that are new are written back. You can choose to commit all changed files, or optionally specify specific files or directories to commit. Each time you commit, Amazon FSx for Lustre only copies data to Amazon S3 that hasn’t already been committed. Amazon FSx for Lustre uses parallel data transfer techniques to commit data at up to hundreds of GBs/s.

Q: If I have data on-premises how do I make it available to Amazon FSx for Lustre to process it?

A: If you have high-performance or data processing workloads running on-premises and demand for computing capacity spikes, you can cloud burst your workloads to Amazon FSx for Lustre by using Amazon Direct Connect or VPN.

Q: What does Amazon FSx for Lustre do to ensure high availability and durability?

A: Amazon FSx for Lustre is designed for high-performance workloads where your long-term data is stored in a data repository such as Amazon S3 or an on-premises data store. Amazon FSx for Lustre is cost-optimized for these workloads by providing high-performance file storage that’s designed to be spun up and down as-needed.

Q: How do I monitor my file system’s activity?
