In this lesson we cover Amazon FSx — a family of fully managed, high-performance file systems for a wide range of workloads. FSx removes the operational burden of provisioning and managing file servers by handling replication, patching, hardware maintenance, and backups on your behalf.
A presentation slide titled "What Is FSx?" showing five colored rounded cards. Each card lists file-server tasks: provisioning file servers and storage volumes, replicating data, patching file servers, addressing hardware issues, and performing manual backups.
FSx vs EFS
  • Both Amazon FSx and Amazon EFS provide managed file storage, but they target different workloads and client operating systems.
  • Amazon EFS is Linux-native and best suited for POSIX workloads.
  • Amazon FSx offers multiple purpose-built file systems (flavors) for Windows-native workloads and specialized use cases such as high-performance computing and enterprise-grade data management.
Key benefits of Amazon FSx
  • Durable, managed file storage for applications with built-in backups and maintenance.
  • AWS manages server provisioning, patching, and hardware replacement.
  • Flexible capacity and performance scaling to match workload demands.
  • Concurrent shared access for multiple clients.
  • Automated backup and snapshot options to protect data.

FSx file system options — choose by workload and compatibility Amazon FSx provides four primary file system types, each optimized for different workloads, protocols, and client OS compatibility:
  1. Amazon FSx for Windows File Server
  • Purpose-built for Windows workloads and fully compatible with Microsoft Windows Server file sharing.
  • Uses the SMB protocol and integrates with Microsoft Active Directory for authentication, access control, and group policies.
  • Supports Windows-specific features such as data deduplication and quotas.
  • Ideal when you require native Windows file semantics and AD integration.
  1. Amazon FSx for Lustre
  • Optimized for high-performance, parallel file processing common in scientific computing, machine learning, and analytics.
  • Built on the Lustre file system for low-latency, high-throughput access and can integrate with Amazon S3 for data import/export.
  • Integrates with AWS services such as AWS DataSync and AWS Batch to support large-scale compute workloads.
  • Designed to scale capacity and throughput to match compute demand.

  1. Amazon FSx for NetApp ONTAP
  • Built on NetApp ONTAP to deliver enterprise-grade data management features and performance.
  • Accessible from Linux, Windows, and macOS using NFS, SMB, and iSCSI protocols.
  • Supports snapshots, clones, tiering, and cross-region replication; suitable for enterprise applications and storage-lifecycle management.
  • Scales to address changing workload requirements with NetApp-compatible features.

  1. Amazon FSx for OpenZFS
  • Managed file system built on the open-source OpenZFS project.
  • Exposes NFS access (Linux and macOS); Windows clients can use NFS clients if required.
  • Leverages OpenZFS features such as compression, snapshots, cloning, and strong data integrity protections.
  • Good fit for workloads that benefit from ZFS data-management capabilities and snapshot-based workflows.

Deployment options and high availability
  • FSx for Windows File Server, FSx for NetApp ONTAP, and FSx for OpenZFS support both single-AZ and multi-AZ deployments to provide high availability and failover.
  • FSx for Lustre is commonly offered in single-AZ configurations (verify current AWS documentation for updates and multi-AZ options).
  • When planning architecture, evaluate your desired RTO/RPO, cross-AZ traffic patterns, and replication requirements.

Quick comparison (at-a-glance)
  • Consider client OS compatibility, protocol support (SMB, NFS, iSCSI, Lustre), latency, throughput, and maximum filesystem size when selecting a flavor.
  • The image below contains a detailed comparison table; the concise table that follows highlights the most common decision points.
A comparison table titled "FSx Comparison" that lists features (client compatibility, protocol support, latency, max throughput, max file system size) for FSx for NetApp ONTAP, FSx for Windows, FSx for Lustre, and FSx for OpenZFS. It shows supported OSes (Windows/Linux/macOS), protocols (SMB, NFS, iSCSI, custom), latency (<1ms to <0.5s), throughput ranges, and filesystem size limits.
When to choose each FSx flavor — practical guidance
  • Choose FSx for Windows File Server when you need native SMB semantics, Group Policy and AD authentication, or Windows-only workloads.
  • Choose FSx for Lustre for large-scale, parallel compute jobs that need high throughput and low latency (e.g., ML training, HPC).
  • Choose FSx for NetApp ONTAP when enterprise data management, multi-protocol access, and NetApp ecosystem compatibility are required.
  • Choose FSx for OpenZFS when you value ZFS features (compression, snapshotting, clones) and NFS access across POSIX systems.
Additional resources Summary
  • Amazon FSx provides fully managed, high-performance file systems tailored to different workloads and client operating systems.
  • Four main options: FSx for Windows File Server, FSx for Lustre, FSx for NetApp ONTAP, and FSx for OpenZFS — each optimized for specific protocols, performance needs, and data-management features.
  • Evaluate client OS compatibility, required protocols, latency/throughput needs, and HA requirements to pick the right FSx flavor.
Choose the FSx flavor that aligns with your client OS, protocol requirements, and performance profile. For Windows-native file sharing and Active Directory integration, FSx for Windows is the natural choice; for high-performance parallel workloads, consider FSx for Lustre.
