Amazon FSx for OpenZFS, a service that provides fully managed file storage powered by the popular OpenZFS file system, now provides 14% higher levels of I/O operations per second (IOPS) at no additional cost, bringing the new maximum IOPS level to 400,000. The increased IOPS levels enable you to improve price–performance for IOPS-intensive workloads like Oracle databases and optimize costs for workloads like periodic reporting jobs with IOPS requirements that vary over time.
