2020 AFS Technologies Workshop

It has been five years since AuriStor and Teradactyl organized the 2015 North American AFS and Kerberos Best Practices Workshop in Pittsburgh PA USA. This year the OpenAFS Foundation is organizing its successor, the AFS Technologies Workshop, a conference open to all community members that use, deploy or develop technologies related to the AFS family of file systems.

Why should you attend?

  • Experience one-on-one time with the AuriStor File System and TiBS developers

  • Network with your peers

  • Learn about latest features and best practices

  • Influence product road maps

  • Receive in-depth technical briefings on recent improvements

AuriStor File System and TiBS Related Talks

Title: AuriStor File System Status Report

An update on major updates to the AuriStor File System in 2019 and 2020 plus a road map of expected deliverables in 2020. This will include real world milestones achieved by end user sites.

Title: NIST 800-171 considerations for storage

Organizations deploying AFS technologies may soon have internal or research data subject to NIST 800-171 security standards under executive orders from both President Obama and President Trump. Funding for U.S. government federal agencies, commercial U.S. government federal contractors, and Educational institutions both domestic and international who are receiving grants or other U.S. government federal aid will become increasingly subject to compliance. Teradactyl will discuss NIST 800-171 requirements for controlled unclassified information. Learn the requirements and how organizations can adopt a compliant backup and archive solution for AFS technologies, HPC environments, and other heterogeneous computing platforms.

Title: Interoperability of AFS and AuriStor with Backup and Restore

OpenAFS and AuriStor continue to develop and introduce new features. Backup and restore software should provide solutions designed to simultaneously recover both of these AFS technologies in the event updates result in unintended and undesired consequences. The solution should also be capable of protecting organizational data in operations running multiple cells, transitioning between the solutions, or deploying both technologies to ensure organizational data integrity and business continuity.

Title: Proposed RX Extensions

AuriStor RX and Linux RX_RPC have pushed the RX protocol to its limits. This talk will present several proposals for RX protocol extensions which could improve the efficiency on LANs and throughput on high throughput high latency networks. These include proposals to increase the effective size of the selective acknowledgment table, negotiate large packet sizes up to 64K, and more.

Title: Linux: kafs, where are you now?

Linux kernel afs (kafs) and AF_RXRPC have inspired the development of many Linux subsystems including keyrings, keyutils, FS-cache, file system namespaces, and the new mount api which in turn have influenced the development of NFS, CIFS, Plan9 and Ceph. This talk discusses the current state of these technologies, how kafs was added to the Fedora Core distribution, and the next steps in its development.

Title: Complying with Key Rotation Policies using AuriStorFS

Many organizations are required to perform key rotation for network services on a regular cycle with typical periods ranging from 60 to 180 days. Key rotation is relatively easy for standalone services such as a host's Kerberos keytab. However, when keys must be rotated for a distributed service a failure to update any one instance's key can result in an outage. This talk will present the techniques that can be used with AuriStorFS to rotate cell-wide rxkad_krb5 and yfs-rxgk keys without the risk of outages.

Title: AuriStorFS for Microsoft Windows

The last version of OpenAFS for Windows, 1.7.33, was released by AuriStor in November 2015. This talk will describe the current status of the AuriStorFS for Windows client and the changes that have been implemented in pursuit of certification by Microsoft.

Additional submissions

Other talks have been submitted for consideration on Heimdal Kerberos, Tiered Secondary Storage, Privacy and Global File Systems, AuriStorFS Performance Milestones, the AuriStorFS Container Storage Interface for Kubernetes, and more.


The OpenAFS Foundation is collecting registration fees for the 2020 AFS Technologies Workshop via EventBrite:

Hotel Recommendation

We encourage all attendees to stay at the Hyatt Place Columbus/OSU as it will provide the greatest access to meet privately with AuriStor and Teradactyl staff throughout the week.

Networking Event

AuriStor and Teradactyl invite all workshop attendees to join us for a special family-friendly networking event at the Columbus Zoo. The Columbus Zoo has been featured on Nat Geo Wild's Secrets of the Zoo.

AuriStor and Teradactyl Training Day

AuriStor and Teradactyl are pleased to invite all AuriStor File System and True incremental Backup System licensees to join us for a FREE day focused on getting the most out of your deployments. The 2020 Training Day is conveniently scheduled Thursday 18 June following the 2020 AFS Technologies Workshop. Training Day will provide Teradactyl and AuriStor the opportunity to present our latest technologies, and discuss subjects at greater depth than can be accommodated by the AFS Technologies Workshop format.
