Amazon FSx for OpenZFS Intelligent-Tiering automatically manages data across three storage tiers—Frequent Access, Infrequent Access, and Archive—based on file access patterns. The addition of eight AWS Regions across the US, Europe, Asia Pacific, and South America broadens availability for customers needing scalable, general-purpose file storage that balances high performance with cost efficiencies. The service includes an optional SSD read cache to improve speed for active data, suitable for file shares, archives, media libraries, and migrations from on-premises HDD storage.
According to Amazon, this Intelligent-Tiering class can reduce costs by up to 85% compared to FSx SSD offerings and 20% versus traditional HDD-based NAS. This automated tiering model requires no customer capacity management, though independent evaluations of cost savings may vary with workload characteristics.
