SANs (Storage Networks) are mainly used to store data offering high performance and low latency. By storing data in a centralized SAN, security, data protection, and disaster recovery tools can be implemented reliably.
Traditional SAN (storage network) allocates storage space to different systems, while vSAN automatically converts local storage resources into a single storage pool. VMWare vSAN is a software-defined storage product used in conjunction with the VMware ESXi hypervisor. It provides and manages policy-based storage regardless of the underlying hardware.
VMWare vSAN reduces the cost and complexity of SAN solutions by providing the ability to deploy policies and rules for storage management. It prevents unauthorized access to data at rest through encryption and also supports deduplication.
