OpenStack Integration with Lightbits Block Storage

This technical white paper presents a performance evaluation of OpenStack when integrated with Lightbits software-defined block storage. The evaluation focuses on I/O patterns that are commonly found in real-world applications, including random read/write and 70/30 mixed workloads. The study utilizes 32 virtual machines across a four-node OpenStack cluster to demonstrate the scalability of IOPS and consistent throughput as concurrency increases. The findings indicate that Lightbits serves as a high-performance storage solution, effectively supporting OpenStack environments that require reliable and efficient block storage. The paper outlines the architecture, configuration, and performance evaluation methodology, detailing how Lightbits integrates with OpenStack Cinder to provide a scalable backend for various workloads. The results validate the performance capabilities of Lightbits in handling demanding application workloads, making it a suitable choice for organizations looking to modernize their OpenStack infrastructure with high-performance storage solutions.
