A report from the OpenAFS Release Team on recent OpenAFS releases, including the OpenAFS 1.8.0 release, the first major release in several years. Topics include acknowlegement of contributors, descriptions of issues recently resolved, and a discussion of commits under review for post 1.8.0.
We would like to have one of the Board members of The OpenAFS Foundation, Inc, speak about this 501(c)(3), US-based, non-profit organization dedicated to fostering the stability and growth of OpenAFS, an open source implementation of the AFS distributed network filesystem. The OpenAFS Foundation adopted a three-fold mission: to attract and increase the community of OpenAFS users, to foster...
The group has been formed to tackle two main themes
- establish a knowledge-sharing community for those operating archival storage for WLCG
- understand how to monitor usage of archival systems and optimise their exploitation by experiments
I will report on the recent activities of this group.
The computing center GridKa is serving the ALICE, ATLAS, CMS and LHCb experiments as one of the biggest WLCG Tier-1 centers world wide with compute and storage resources. It is operated by the Steinbuch Centre for Computing at Karlsruhe Institute of Technology in Germany. In April 2017 a new online storage system was put into operation. In its current stage of expansion it offers the HEP...
CERN IT Storage (IT/ST) group leads the development and operation of large-scale services based on EOS for the full spectrum of use-cases at CERN and in the HEP community. IT/ST group also provides storage for other internal services, such as Open Stack, using a solution based on Ceph. In this talk we present current operational status, ongoing development work and future architecture outlook...
Last May it was announced "AFS" was awarded the [2016 ACM System Software Award][4]. .This presentation will discuss the current state of the AFS file system family including:
- IBM AFS 3.6
- [OpenAFS][1]
- [kAFS][2]
- [AuriStor File System][3]
IBM AFS 3.6 is a commercial product no longer publicly available.
OpenAFS is fork from IBM AFS 3.6 available under the [IBM Public...
The ever-decreasing cost of high capacity spinning media has resulted in a trend towards very large capacity storage ‘building blocks’. Large numbers of disks - with up to 60 drives per enclosure being more-or-less standard – indeed allow for dense solutions, maximizing storage capacity in terms of floor space, and can in theory be packed almost exclusively with disks. The result are building...
After the successful adoption of the CMS Federation an opportunity arose to cache xrootd requests in Southern California. We present the operational challenges and the lessons learned from scaling a federated cache (a cache composed of several independent nodes) first at UCSD and the scaling and network challenges to augment it to include the Caltech Tier 2 Site. In which would be a first of...
One future model of software deployment and configuration is containerization.
AFS has been used for software distribution for many decades. Its global file namespace, the @sys path component substitution macro which permits file paths to be platform-agnostic, and the atomic publication model ("vos release") have proven to be critical components of successful software distribution systems...
