VMware Virtual SAN is a radically simple, enterprise-class shared storage solution for hyper-converged infrastructure optimized for today’s all-flash performance. Virtual SAN delivers enterprise-class availability that covers several areas of potential failures including software, hardware, and other potential infrastructure failures to satisfy the availability requirements of the most demanding business-critical applications. Virtual SAN is the only hyper-converged storage solution delivered directly from the hypervisor, resulting in a flash-optimized architecture that delivers as much as 100,000 IOPS per all-flash node.
