Comparison of Lightbits and Ceph for Private Clouds

This white paper compares Lightbits and Ceph, focusing on their architecture, performance, transactions per second (TPS), and total cost of ownership (TCO) in the context of private clouds utilizing NVMe over TCP. It outlines how both solutions deliver software-defined storage (SDS) on commodity x86 servers, yet differ significantly in their architectural approaches, impacting performance and cost efficiency. The document provides detailed performance metrics, demonstrating that Lightbits achieves significantly higher IOPS and throughput compared to Ceph under identical conditions. It also discusses the evolution of NVMe over Fabrics, particularly NVMe/TCP, as a preferred transport for private clouds due to its ability to run on standard Ethernet and scale horizontally. The paper further examines the implications of these architectural differences on operational efficiency and performance in cloud-native environments, emphasizing the advantages of Lightbits for high-performance workloads. The conclusion summarizes the findings and reinforces the distinctions between the two storage solutions.
