Sandia National Laboratories in Albuquerque, New Mexico teamed up with Hewlett-Packard Enterprise in Palo Alto, CA to design, deliver and install the world’s fastest Arm-based supercomputer according to the TOP500 list – Astra. This is the story of Astra’s primary all flash, 200+ GB/sec, Lustre filesystem supporting this Arm-based workhorse. This presentation will first cover Astra’s requirements, and the design and architecture for a filesystem of the scale needed to support the new Astra machine. Then the process of deployment, testing, and validation of performance will be discussed. The presentation will include some of the lessons learned along the way providing additional insight into the effective and valuable collaboration between Sandia National Laboratories and Hewlett-Packard Enterprise in making Astra and it’s all flash Lustre filesystem a reality.
