A significant advantage of Oracle Cloud Infrastructure (OCI) is the frictionless block storage management, regarding size (Resizing a Volume) and performance (Block Volume Performance). The OCI Block Volume service uses NVMe-based storage infrastructure, designed for consistency, and offers flexible and elastic performance. You only need to provision the capacity needed and performance scales with the performance characteristics of the performance level selected up to the service maximum.

You don’t need to determine your performance needs ahead of creating and attaching block volumes. When you create a volume, by default, it’s configured for the Balanced performance level. You can change this level when create the volume, or you can update it at any point after the volume is created. The elastic performance capability of the service enables you to pay for the performance characteristics you require independently from the size of your block volumes and boot volumes. If your requirements change, you only need to adjust the performance settings for the volume, you don’t need to recreate your volumes.

Block Volume provides dynamic performance scaling with autotuning. For more information, see Dynamic Performance Scaling.

If you have video surveillance and analytics software performance workloads, have a look to our blog post, where we show our outstanding block volume performance in a real life scenario.

OCI service level agreement

Enterprises demand more than just availability from their cloud infrastructure. Mission-critical workloads also require consistent performance, and the ability to manage, monitor, and modify resources running in the cloud at any time. Only Oracle offers end-to-end service level agreements (SLAs), covering performance, availability, and manageability of services. Oracle provides industry-leading a block volume performance SLA. The block availability, manageability, and performance numbers are outlined in Section 3.6.16 Oracle Cloud Infrastructure - Block Volume of the Oracle PaaS and IaaS Public Cloud Services Pillar documentation.

Performance out of this world

OCI Block Storage Performance per Instance outperform the competition regarding throughput and provide almost triple IOPS compared to the second best.

Cloud provider GB/s per Instance IOPS per instance
OCI 12 1,300,000
Amazon Web Services 10 400,000
Microsoft Azure 8 450,000
Google Cloud Platform 10 500,000


Senior Principal Product Manager Max Verun provides more details in his blog post, Shatter the Million IOPS Barrier on the Cloud with OCI Block Storage. But talking isn’t enough. Let’s prove it. With OCI Block Storage Plan & Proof, we provide you with the following benefits:

  • PLAN: Here, you insert your requirements (size, throughput, and IOPS). We analyze OCI Block Storage performance capabilities for you. Based on these factors, you get the optimal Compute shape, including the number of needed block volume and performance details, such as shape, number of OCPUs and block volumes, size, and volume performance units (VPUs).

  • PROOF: With our automated PROOF scripting, you can provide the outcome of PLAN (shape, number of OCPUs and block volumes, sizes and VPU) and we automatically proof the performance in your tenancy. So, you get the real numbers in your individual environment.

Test us! We deliver and guarantee with our SLA.
