Session II: Status and Development Trends

Presentation

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...

Session I: Operational Experiences and Aspects

Presentation

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,...
