VMware vSAN is an enterprise-grade, hyper-converged, software-defined storage solution optimized for VMware virtual machines (VMs) that is natively embedded in the vSphere hypervisor. vSAN provides service-level and policy management at the VM and VM disk (VMDK) levels, provides performance quality of service (QoS) capability at the VM level, and allows enterprise-grade scalability for capacity and performance without the need for a large upfront investment.
vSAN enables the use of the RPC-VMware environment to manage and provision storage through self-service and to offer role-based self-service access to other users within the organization. vSAN allows the storage policy to be set for availability, performance, and QoS at the VM and VMDK levels, while eliminating the concept of logical unit number (LUN) volume and redundant array of independent disks (RAID) to make storage provisioning and management simple for use by a VMware administrator. In addition, vSAN also allows for integration into VMware vRealize Operations™ and VMware vRealize Automation™ to provide end-to-end SDDC manageability and service delivery.
