Amazon FSx¶
Definition¶
Amazon FSx is AWS's managed file-storage family for purpose- specific filesystems beyond the generic NFS provided by EFS: Windows File Server (SMB), Lustre (HPC), NetApp ONTAP (enterprise), OpenZFS. Each FSx variant exposes the native semantics of the underlying filesystem family as a managed service.
Stub page — coverage limited to what ingested sources describe.
Variants¶
Amazon FSx is a family of four managed file systems: - FSx for Windows File Server — SMB, Active Directory - FSx for Lustre — HPC/ML parallel file system - FSx for NetApp ONTAP — enterprise multi-protocol (NFS/SMB/iSCSI) with ONTAP data management (SnapMirror, FlexClone, tiering) - FSx for OpenZFS — Linux workloads migrating from on-prem ZFS
For the NetApp ONTAP variant's DR capabilities (SnapMirror replication + FlexClone rapid failover), see systems/amazon-fsx-for-netapp-ontap.
DR role¶
The 2026-03-31 AWS DR-streamlining post ([[sources/2026-03-31-aws- streamlining-access-to-dr-capabilities]]) names FSx (alongside EFS) as a service that previously had no first-party backup until AWS Backup added coverage — one of the canonical examples of AWS Backup closing a service-specific gap.
Seen in¶
- sources/2026-03-31-aws-streamlining-access-to-dr-capabilities — named as an AWS Backup coverage-gap closure (FSx had no native backup before AWS Backup added it).
- sources/2026-04-06-aws-unlock-efficient-model-deployment-simplified-inference-operator-setup-on-amazon-sagemaker-hyperpod — FSx CSI driver bundled as one of the four default dependency add-ons installed by AWS's SageMaker HyperPod Inference Operator EKS add-on (alongside cert-manager, S3 Mountpoint CSI driver, metrics-server). Canonical instance of FSx as a managed-inference-stack default: Lustre / NetApp ONTAP / OpenZFS filesystems presented to inference pods through the standard Kubernetes CSI interface with the driver lifecycle owned by AWS.
- sources/2026-07-07-aws-sp-globals-disaster-recovery-fsx-netapp-ontap — FSx for NetApp ONTAP as the cross-region DR storage layer for S&P Global's Capital IQ platform; SnapMirror + FlexClone enable sub-15-minute read-only failover.
