Big Data & Data Management
Oral Presentation
The Scientific Data and Computing Center (SDCC) at Brookhaven National Laboratory (BNL) is a major scientific data storage site with more than 100 PB of archived experimental data, which amount is supposed to grow exponentially during the next several years. BNL is a Tier 1 data center for the ATLAS collaboration.
The challenge is to meet the data storage and processing requirements of the...

Oral Presentation
Machine and Deep Learning techniques are being used in various areas of CMS operations at the LHC collider, like data taking, monitoring, processing and physics analysis. A review a few selected use cases shows the progress in the field, with highlight on most recent developments, as well as an outlook to future applications in LHC Run III and towards the High-Luminosity LHC phase.

Oral Presentation
Much attention is paid to the process of how new storage services are deployed into production that the challenges therein. Far less is paid to what happens when a storage service is approaching the end of its useful life. The challenges in rationalising and de-scoping a service that, while relatively old, is still critical to production work for both the UK WLCG Tier 1 and local facilities...

Oral Presentation
RAL has developed a disk storage solution based on Inktank and Red Hat's ‘Ceph’ object storage platform to support the UK's WLCG Tier One centre. This solution, known as 'Echo' (Erasure-Coded High-throughput Object store), is now providing ~40% of the disk storage available to the LHC experiments and wider WLCG at the UK Tier 1.
Data is stored in the cluster using erasure coding to reduce...

Oral Presentation
As a robust and scalable storage system, dCache has always allowed the number of storage nodes and user accessible endpoints to be scaled horizontally, providing several levels of fault tolerance and high throughput. Core management services like the POSIX name space and central load balancing components however are merely vertically scalable. This greatly limits the scalability of the core...

EOS Open Storage platform is a software solution for central data recording, user analysis and data processing.
In 2017 the EOS system at CERN provided 250 PB of disk storage on more than 50k disks. Most of the stored data originates from the Large Hadron Collider and various other experiments at CERN.
Originally developed as a pure disk storage system, EOS has been extended with...
