Ranch Maintenance, March 22-25

Ranch will be unavailable for an extended maintenance from 5:00 PM (CT) Friday, March 22, through 9:00 AM Monday, March 25, 2019.

Ranch will be unavailable for an extended maintenance from 5:00 PM (CT) Friday, March 22, through 9:00 AM Monday, March 25, 2019. During this maintenance, the current Ranch archive will transition to a new support infrastructure based on Quantum StorNext hardware and software technology.

Detailed information will be available in a transition guide and an updated Ranch user guide. Both guides are currently under development and will be released when the new system enters production.

After over two decades of operation, the Ranch system has more than 49,000 users. What has been revealed after running Ranch for so long, with so many users, is that continuing to support file storage quotas, implementing a total file count quota, and enforcing explicit data retention periods are the keys to the sustainability of the Ranch archiving environment over the long-term.

In the new environment each user will have a default file quota of 50,000 files and 2TB of storage in their personal directories. Additionally, a "project" directory structure will be implemented to support both shared and user directories that exceed the 2TB per user quota. These "project" directories will be set up only upon PI request, with appropriate file count and file size quotas, a defined retention period, and group permissions allowing shared access.

On March 25, 2019 at 9:00 AM, when users are allowed back onto the Ranch system, all current Ranch user home directories will reside within the new system. These directories will be empty, except for a link (./old_HSM) that will point to the users’ old Ranch directories. Users will have access to their existing data, read-only, through March 31, 2020.

Users are encouraged to migrate the data that they need to keep beyond March 31, 2020 by copying ONLY that data from their existing Ranch directory into their new personal directory. As the file quota of 50,000 files will be in effect for this new directory, using tar or some other methodology will be necessary to keep file count beneath quota for both any migrated data and all new incoming data.

The Texas Advanced Computing Center (TACC) will be deploying a new system, Frontera, in mid-2019, with support from the U.S. National Science Foundation as the first phase of the new NSF "Towards a Leadership Class Computing Facility" program.

This webinar will provide a brief overview of the plans for the new system and the broader project that surrounds it, review the architectural design choices made, and discuss the application community that will run on it. The presentation will also provide an update on the current landscape of systems at TACC, how they are used, and how usage is changing. 


This is the first of the upcoming series of Frontera training webinars. Please also join us for “MPI Foundations” on March 25 and “Programming for Advanced Architectures” on March 29. We’ll continue to send announcements for future Frontera training offerings.
