Located at Oak Ridge National Laboratory (ORNL), Frontier has a performance of 1,102 Efflops and a peak performance of 1,685 Efflops, making it the first supercomputer to break the exascale threshold.
The Orion storage system consists of 50 storage cabinets with a total capacity of approximately 700 PB (700 million gigabytes). The system uses a three-tier scheme that includes SSDs, hard drives, and other non-volatile solutions, as well as the Luster and ZFS file systems.
The first tier, known as the performance tier, consists of 5400 NVMe SSDs providing 11.5 PB of storage capacity. Top performance read and write speeds of 10 TB/s and random read and write IOPS (Input/Output Operations Per Second) exceed 2 million.
The second level contains 47,700 hard drives with a total capacity of 679 Petabytes. The maximum read speed of the array is 4.6 TB/s and the maximum write speed is 5.5 TB/s.
The third layer, which contains 480 NVMe devices with a total capacity of 10 PB, is responsible for processing metadata.
