Oral presentation
The reliability of hard disk drives (HDD) has been quantified historically by a mean time to failure (MTTF), or an annualized failure rate (AFR), defined at a specified operating temperature, and an assumed functional duty cycle. We provide justification for replacing the ambiguous concept of duty cycle with the readily quantifiable “workload”, which is defined as the total amount of data...

The goal of the HEPiX Bit Preservation Working Group is to share ideas, practices and experience on bit stream preservation activities across sites providing long-term and large-scale archive services. Different aspects should be covered like: technology used for long-term archiving, definition of reliability, mitigation of data loss risks, monitoring/verification of the archive contents,...

Oral presentation
The CMS T1 facility at Fermilab manages many tens of petabytes of data for CMS. This talk will present some historical information on the solutions used to store this data as well as information on the new solutions we are in the process of implementing and how we got to where we are now.

This presentation is intended to bring HEP storage administrators up to speed with ongoing dCache developments and activities.
In the context of WLCG, we will report on our collaboration with the xRootd folks in terms of federated storage and monitoring,
our efforts to support the strict separation of CMS between disk and tape storage endpoints,
and we hope to have the first results on...

This is a report on CERN IT's 3 PetaByte Ceph pre-production cluster set up in the past couple of months which will initially serve as a storage backend for OpenStack images and volumes (backends for AFS or NFS servers are options we will explore as well). In addition to a discussion of the architecture and configuration of the cluster, we will present results of our functionality tests, some...
