Storage & Filesystems
There are terabytes of data stored in a relational database (Oracle) at CERN which in fact does not need a relational model. Moreover, using a relational database management system very often brings a significant overhead in terms of resource utilization. The problem is notably observable for warehouse-type data sets. At the same time running analytical workloads on such data sets requires...

Storage & Filesystems
Recent advances in both, hard-disks and system-on-a-chip (SoC) designs enabled the development of a novel form of hard-disk: a disk that includes a network interface and an additional ARM processor, not involved in low level disk operations. This setup allows those disks to run an operating system and to communicate with other nodes autonomously using wired Ethernet. No additional hardware or...

PETRA III is DESY's largest ring accelerator and the most brilliant storage-ring-based X-ray radiation source in the world.
With its recent extension, new and faster detectors are used for the data acquisition.
They exceed previous detectors in terms of data rate and volume; this is highly demanding for the underlying storage system.
This talk will present the challenges we faced, the new...

The presentation will present:
- History and current status of the BeeGFS project (formerly know as FhGFS, originating from Fraunhofer)
- Design and technology decisions made by BeeGFS developers
- BeeGFS setup and operational experience as IniniBand based high-performance cluster file system serving as scratch space for the DESY HPC system
- Discussion of future usage scenarios and...

RAL is currently exploring the possibilities offered by Ceph. This talk will describe two of these projects. The first project aims to provide large scale, high throughput storage for experimental data. This will initially be used by the WLCG VOs. A prototype cluster built from old hardware has been in testing since October 2014. The WLCG VOs will continue to need to access their data via...

Ceph has become over time a key component of CERN’s Agile Infrastructure by providing storage for the Openstack service.
In this talk, we will briefly introduce Ceph’s concepts, our current cluster and the services we provide such as NFS filers, Object Store for the Atlas experiment and Xroot-to-Ceph gateways.
We will then talk about our experience running Ceph with some real-world...

We review various functionality, performance, and stability tests performed at the RHIC and ATLAS Computing Facility (RACF) at Brookhaven National Laboratory (BNL) in 2014-2015. Tests were run on all three (object storage, block storage and file system) levels of Ceph, using a range of hardware platforms and networking solutions, including 10/40 Gbps Ethernet and IPoIB/4X FDR Infiniband. We...

The Ceph storage system is an open source, highly scalable, resilient data storage service providing object, block and file interfaces. This presentation will introduce what is new in the latest Ceph release, codenamed *Hammer*, and describe the ongoing development activities around CephFS, the Ceph filesystem.
An intermediate level of familiarity with large scale storage systems will be assumed.
