Enhance vSAN Performance by enabling RDMA

Remote Direct Memory Access (RDMA) can significantly boost VMware vSAN's performance by enabling low-latency, high-throughput data transfers directly between the memory of different hosts. This reduces CPU overhead and enhances overall efficiency. By leveraging specifically, RoCE v2 (RDMA over Converged Ethernet), VMware vSAN can achieve improved IOPS and reduced latency, making it ideal for demanding workloads. For VDI workloads, such as those managed by Omnissa/VMware Horizon, RDMA can significantly improve the user experience. By reducing the latency and increasing the throughput of data transfers, RDMA ensures that virtual desktops respond more quickly and smoothly, even under heavy load. This is particularly beneficial for environments with many users, as it helps maintain consistent performance and responsiveness. However, not all hardware constellations support RDMA out of the box without performing specific configuration. The purpose of this article is to describe diffe
