ATS Seminar Series: John Bent

The Advanced Technologies Section (ATS) of the National Center for Computational Sciences at ORNL is a world leader in developing and deploying scientific and technical solutions for leadership-class computing environments. The R&D activities of ATS are organized around designing and deploying leadership class systems, developing artificial intelligence solutions for science and smart facilities of the future, and stewardship of data and workflows at scale to enable science. The ATS Seminar Series is a forum for learning from experts and engaging with collaborators to advance their scientific mission.


Seminar Title:

Seagate’s CORTX: Mass-Capacity Optimized Object Storage

In this talk, Seagate Senior Director John Bent will present the motivation, architecture, and current status of CORTX, Seagate’s S3 compatible object storage system. When data centers ask Seagate for a data platform, we are unable to just dump 1000’s of drives onto their data center floor. Transforming these drives into a single, self-healing, resilient, durable, consistent data platform that maximizes the ratio of usable to raw capacity is a challenge that can be uniquely answered by Seagate. This is due to our ability to vertically codesign the devices, the enclosures, and the distributed software. This talk will examine some of the challenges in building this system and some of the optimizations uniquely available to Seagate. The talk will additionally include a discussion of the past, present, and future of durability architectures.
