Amazon FSx

Amazon FSx provides managed Windows File Server, Lustre, NetApp ONTAP, and OpenZFS file systems so workloads can retain familiar file protocols and specialized storage capabilities.

File-system selection and cost planning

Amazon FSx Pricing: Windows, Lustre, ONTAP & OpenZFS

Amazon FSx is a family of managed file systems, so the first decision is the file-system technology and workload fit. Protocol, deployment type, capacity, throughput, IOPS, backup, and migration requirements must be evaluated for that family rather than for FSx as one uniform service.

Which Amazon FSx file system should I choose?

Choose Windows File Server for Windows and SMB workloads, Lustre for high-performance parallel processing, NetApp ONTAP for ONTAP data-management capabilities, or OpenZFS for ZFS-based Linux workloads. Validate protocol and feature requirements against the family-specific guide.

What drives Amazon FSx pricing?

Estimate the selected file-system family and deployment type, storage capacity and media, throughput capacity, provisioned IOPS where applicable, backups, and network transfer. The billing dimensions and available tiers differ by family.

How should I plan an FSx migration?

Measure protocol behavior, throughput, IOPS, latency, metadata, and recovery needs before sizing. Use DataSync or a supported native replication path for controlled migration, then test mounts, permissions, failover, backup, and restore before cutover.

  • AWS DataSync — Use DataSync for supported, verified migrations into or between FSx file systems.
  • AWS Backup — Use AWS Backup where the selected FSx family and recovery policy are supported.
  • AWS Key Management Service — Use KMS keys where customer-managed encryption control is required.

Why implement Amazon FSx?

  • Offers purpose-built file systems for Windows applications, HPC, enterprise NAS, and Linux workloads without operating the underlying storage servers.
  • Preserves familiar protocols and features such as SMB, NFS, Lustre, snapshots, replication, or storage efficiencies according to the selected family.
  • Provides managed availability, backups, patching, and capacity or throughput controls integrated with AWS networking and security.

How to implement Amazon FSx

  1. Choose Windows File Server, Lustre, ONTAP, or OpenZFS from protocol, latency, throughput, data-management, and compatibility requirements.
  2. Design VPC subnets, routing, security groups, directory integration where required, encryption keys, deployment type, storage capacity, and throughput settings.
  3. Mount from supported clients, validate permissions and failover behavior, then configure backups, monitoring, maintenance windows, and scaling procedures.

Amazon FSx best practices

  • Use the file-system-specific guide rather than assuming tuning, protocol, backup, or high-availability behavior is identical across FSx families.
  • Place clients close to the file system, allow only required protocol traffic, encrypt data, and monitor capacity, throughput, IOPS, latency, and client connections.
  • Test backups and failover, size throughput from observed workload behavior, and use DataSync or native replication features for controlled migrations.

Amazon FSx use cases and server impact

  • Windows home directories and business applications
  • Lustre HPC and machine-learning datasets
  • Managed ONTAP or OpenZFS enterprise file workloads

Replaces specialized Windows, Lustre, ONTAP, or OpenZFS storage servers while retaining file-system protocols and client-side integration responsibilities.
