Mr Philipp Falk
Data-heavy workloads demand flexible and efficient storage strategies. In this session, the BeeGFS VP of Engineering will present BeeGFS auto-tiering capabilities, demonstrating how data can be dynamically placed across different storage tiers, including internal BeeGFS systems and external S3-based storage to balance performance, scalability, and cost.

This presentation will provide an update on activities in the DAOS Foundation including the upcoming DAOS 2.8 release, first experiences of deploying DAOS on 400Gbps fabrics (IB-NDR, Slingshot 400, OPA 400, RoCE), a preview of the HPE Cray Supercomputing Storage K3000 product based on DAOS, and other notable research and development topics from the DAOS community.

Ad hoc filesystems across node-local SSDs can help alleviate the I/O bottleneck imposed by an HDD-backed shared filesystem, aiding efficient compute resource utilization. In an attempt to reduce strain on the global storage and make better use of node local storage, GekkoFS is under examination for TU Dresden's HPC systems. I highlight our considerations for an ad hoc filesystem as well as...

- the Lustre Trashcan/undelete feature; and
- the Lustre quota aggregation feature. -
Janos Zimmermann (German Climate Computing Center)Session I: Operational Experiences and AspectsPresentation
We operate a 120 PiB Lustre filesystem at DKRZ with billions of inodes. At the same time, climate and Earth system workflows are increasingly moving toward chunked, object-style formats such as Zarr. While this shift enables scalable and cloud-aligned data access patterns, it also dramatically increases inode counts. As a result, traditional namespace traversals become slow,...

Cyril BAUDRY (EDF)Session I: Operational Experiences and AspectsPresentation
EDF has been using HPC computing for many years in its R&D and production activities. After a brief introduction to the challenges of HPC computing, we will provide an overview of our storage systems for computing and long-term storage. We will then present the difficulties encountered with our current configurations. We will conclude this presentation with new opportunities related to...

In the era of exascale computing and data-intensive workflows, efficient tiered storage architectures are essential to balance performance, capacity, and cost. While parallel file systems like Lustre, BeeGFS, and DAOS excel at handling high-throughput I/O, the seamless integration of high-capacity, long-term storage solutions such as tape libraries remains a major challenge for long-term data...

As supercomputers are becoming faster and faster, so does their data output. Since the regularly accessed data must be stored and available quickly to users, it is important to put it on fast storage systems. However, these tend to have a low capacity, meaning we must be able to chose the data which should remain on those types of storage systems, and which can be placed on slower but more...
