ConnectX® Ethernet Driver for VMware® ESXi Server.

HCI Bench v2.5.3 VDBENCH will be used for benchmarks to show performance improvements between vSAN over RDMA and TCP protocols by using the same hardware.

This document provides instructions on how to configure vSAN over RoCE Datastores located on local NVMe disks in VMware vSphere 7.0 U2 over NVIDIA end-to-end 100 Gb/s Ethernet solution. VMware’s vSANoRDMA is now fully qualified and available as of the ESXi 7.0 U2 release, making it ready for deployments. RDMA technology is already widely used for efficient data transfer in render farms and large cloud deployments, such as HPC (including machine/deep learning), NVMe-oF and iSER-based storage, NFSoRDMA, mission-critical SQL databases such as Oracle’s RAC (Exadata), IBM DB2 pureScale, Microsoft SQL solutions and Teradata.įor the last several years, VMware has been adding RDMA support to ESXi, including PVRDMA (paravirtual RDMA) to accelerate data transfers between virtual servers and iSER and NVMe-oF for remote storage acceleration. Throughput is increased, latency reduced and the CPU is freed to run applications. RDMA makes data transfers more efficient and enables fast data movement between servers and storage without using the OS or burdening the server’s CPU. RDMA (Remote Direct Memory Access) is an innovative technology that boosts data communication performance and efficiency. VSAN aggregates local, direct-attached storage devices to create and share a single storage pool across all hosts in the hyperconverged cluster, utilizing faster flash SSD for cache and inexpensive HDD to maximize capacity. Deploying virtual machine storage policies, users can define storage requirements and capabilities. vSAN eliminates the need for external shared storage and simplifies storage configuration through storage policy-based management.

VSAN is VMware’s enterprise storage solution for SDS that supports hyperconverged infrastructure systems and is fully integrated with VMware vSphere as a distributed layer of software within the ESXi hypervisor. Also widely adopted: high-performance Ethernet for server-to-server and server-to-storage communication. Taken together, these enable a software-defined data center. These architectures include three core technologies: software-defined-compute (or server virtualization), software-defined-networking and software-defined storage (SDS). To meet demands, provide services and allocate resources efficiently, enterprise IT teams have deployed hyperconverged architectures that use the same servers for compute and storage. Hybrid cloud has become the dominant architecture for enterprises seeking to extend their compute capabilities by using public clouds while maintaining on-premises clusters that are fully interoperable with their cloud service providers.
