About
[Recent developments in XFS][1] have introduced native support for zoned storage devices such as Shingled Magnetic Recording (SMR) drives, offering a robust and higher‑performance alternative to BTRFS for this class of hardware. With Zoned XFS EOS can now efficiently leverage the additional 20–25% storage capacity provided by SMR HDDs.
This presentation will give an overview of the architectural changes made to XFS to support zoned storage, demonstrate its performance characteristics, and provide a practical, hands‑on guide for setting up, using and tuning XFS file systems on SMR HDDs.
