Performance benchmark results: Amazon Web Services (AWS) SAN in the Cloud featuring Elastic Block Storage (EBS) io2 Block Express volumes and an Elastic Cloud Compute (EC2) r5b.24xlarge instance vs. comparable on-premises all-flash SAN solution

If your organization uses on-premises storage area network (SAN)-based storage, you might be familiar with its benefits, such as significant capacity, quick performance for transactional databases, and reliability. However, as the storage ages, maintaining performance or capacity for data growth could be difficult. To meet this need and support workloads that require low latency and high throughput, AWS offers an on-demand SAN in the Cloud solution comprised of a single data volume backed by two EBS io2 Block Express volumes and an EC2 r5b.24xlarge instance.

We ran benchmarking tests to compare transactional database performance of this Amazon SAN in the Cloud solution and an on-premises mid-level HPE 3PAR StoreServ 8450 SAN solution that we configured similarly to the AWS solution. We ran a synthetic I/O workload and an online transaction processing (OLTP) workload on the two solutions. Both the instance and the on-premises solution used Intel® Xeon® processors from the same generation (Cascade Lake), featured the same number of cores and threads, and offered the same amount of memory. To learn more about our configurations and why we chose them, see the full report.

We found that the AWS SAN in the Cloud solution featuring an EC2 R5b instance and EBS io2 Block Express storage:

  • Delivered 26 percent higher throughput during a synthetic I/O workload. In a 100-percent sequential-read I/O profile with 64k-sized blocks, the EBS io2 Block Express storage and EC2 r5b instance offered greater throughput (in GB per second) compared to the on-premises SAN solution.
  • Processed 3 percent more NOPM for an OLTP workload. The EC2 r5b.24xlarge instance backed by two EBS io2 Block Express volumes processed more new orders per minute (NOPM) than the on-premises SAN solution, a three percent gain.

With the performance we saw from an AWS SAN in the Cloud solution of EBS io2 Block Express volumes and an EC2 r5b instance, your business could lift and shift business-critical OLTP workloads to free up on-premises SAN capacity for other workloads, meeting current usage levels and getting scalability for data growth.
