Community Edition
Free of charge. A single volume (up to 5 TiB / 5M files) with full POSIX compliance, all four cloud backends, local on-disk caching, Kubernetes static provisioning, and the analyze, dedup, find, manage, and update CLI utilities.
Welcome to flexFS™
FlexFS is a high-performance network filesystem that provides POSIX-compatible access to Amazon S3, Google Cloud Storage, Azure Blob Storage, and Oracle Cloud Infrastructure Object Storage. Applications read and write files using standard filesystem calls — flexFS handles block storage, caching, compression, and encryption transparently. Mount clients access storage directly, so aggregate throughput scales linearly with the number of clients.

Key Capabilities
Section titled “Key Capabilities”Elastic Throughput
Mount clients access storage directly — aggregate throughput scales linearly with the number of clients.
Proxy Groups
CDN-like caching layer with automatic lowest-latency proxy selection and writeback caching for hybrid cloud deployments. (Enterprise)
Time Travel
Mount any volume at a specific point in time using --atTime. Read-only access to historical data for auditing, recovery, and compliance.
Zero-Downtime Updates
Mount clients auto-update in place — no unmount, no interruption, no data loss.
End-to-End Encryption
AES-256 encryption; keys are derived on the client and never leave the host. Encryption and decryption happen on the client. (Enterprise)
Four Cloud Backends
Amazon S3 (and S3-compatible stores), Google Cloud Storage, Azure Blob Storage, and Oracle Cloud Infrastructure Object Storage.
Kubernetes Native
CSI volume driver with Helm chart for static provisioning and dynamic provisioning (Enterprise). Mount flexFS volumes directly into pods.
Full POSIX Compliance
ACLs, extended attributes, file locking, hard links, symlinks, and special files. Drop-in replacement for traditional network filesystems.
