Compute NVMe Performance

The content in the sections below apply to Section 3.6 of the Oracle PaaS and IaaS Public Cloud Services Pillar documentation.

Oracle Cloud Infrastructure provides a variety of instance configurations in both bare metal and virtual machine (VM) shapes. Each shape varies on multiple dimensions including memory, CPU cores, network bandwidth, and the option of local NVMe SSD storage found in DenseIO and HPC shapes.

Oracle Cloud Infrastructure provides a service-level agreement (SLA) for NVMe performance. Measuring performance is complex and open to variability.

An NVMe drive also has non-uniform drive performance over the period of drive usage. An NVMe drive performs differently when tested brand new compared to when tested in a steady state after some duration of usage. New drives have not incurred many write/erase cycles and the inline garbage collection has not had a significant impact on IOPS performance. To achieve the goal of reproducibility and reduced variability, our testing focuses on the steady state duration of the NVMe drive's operation.
