NVMe over RDMA
NVMe over RDMA (NVMe-of) is a high-performance storage networking protocol that enables direct access to NVMe (Non-Volatile Memory Express) storage devices over a network using RDMA (Remote Direct Memory Access). It bypasses the host CPU and operating system overhead by allowing data to be transferred directly between the memory of a client and a storage server, reducing latency and improving throughput. This technology is commonly used in data centers and high-performance computing environments to provide scalable, low-latency storage solutions.
Developers should learn NVMe over RDMA when building applications that require ultra-low latency and high-throughput storage access, such as in-memory databases, real-time analytics, or AI/ML workloads. It is particularly useful in cloud-native and microservices architectures where storage needs to be decoupled from compute resources while maintaining performance. Use cases include distributed storage systems, hyper-converged infrastructure, and high-frequency trading platforms.
