34. The CERN Storage Services Strategy

Mr Jakub Moscicki (CERN)

24/04/2012, 14:00

Storage & Filesystems

CERN IT is faced with a rich set of requirements when it comes to the provisioning of storage services. This talk will give an overview of the challenges and constraints, describe which part of the phase space the current services (AFS, CASTOR, EOS) cover and present the short- and mid-term storage strategy. In addition, the current status of ongoing investigations of alternative storage...

Storage & Filesystems

CERN's current backup and archive service hosts 5.5 PB of data in more than 1.6 billion files. We have over 1200 clients which back up or restore an average of 50 TB of data each day. At the current growth rate, we expect to have about 7 PB by the end of 2012. In this contribution we present CERN's backup and archive service based on the IBM Tivoli Storage Manager. We show the...

37. The Infiniband based lustre at GSI

Storage & Filesystems

CESNET, the Czech national research and education network provider, does not only provide plain network connectivity. CESNET coordinates and builds e-infrastructure services nowadays. Among them, national storage facility is being put into operation. The aim of the project is to provide more than 15PB of storage in three geographically distributed data centers for research and science...

38. Data Protection Technologies: What comes after RAID?

Dr Vladimir Sapunenko (INFN)

24/04/2012, 16:05

Storage & Filesystems

Increasing data volumes and demand for access impose serious challenges for data storage infrastructures. Risk of data corruption increases over time, increase of disc size leads to an unacceptably long recovery time in usual RAID configurations. Recently a new solution, erasure coding, has appeared in the Cloud. It is based on a mathematical construction and involves dividing the data into...

8. Evolving the AFS Service at CERN

Mr Jakub Moscicki (CERN)

24/04/2012, 16:35

Storage & Filesystems

In order to provide a scalable service, the AFS infrastructure at CERN currently undergoes an architectural change from Fibre Channel based fabrics towards external SAS based storage. This talk will present the design choices taken, cover the technologies involved, highlight the features and discuss limitations along with their potential solutions.
