A research company runs a high-performance computing (HPC) workload on a fleet of hundreds of Linux EC2 instances. The workload processes large genomics datasets that currently reside in an Amazon S3 bucket. The compute nodes require a POSIX-compliant shared file system that can deliver hundreds of gigabytes per second of throughput and sub-millisecond latencies while processing the data, and results must be written back to S3 when jobs complete. Which storage solution best meets these performance requirements?
