[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...

This project aims to evaluate next-generation, high-density flash-based storage technologies through a strategic CERN openlab – Pure Storage collaboration. By combining CERN’s exascale operational expertise with Pure Storage’s high-efficiency DirectFlash platform, the initiative will assess performance, scalability, energy efficiency, cost, and reliability. The overall goal is to determine...
