VMware vSAN (Virtual Storage Area Network) a software-defined storage.

VMware vSAN is a software-defined storage solution that pools the local disks from multiple ESXi hosts in a vSphere cluster to create a single, shared, distributed datastore, eliminating the need for external SANs and enabling Hyper-Converged Infrastructure (HCI). It's integrated directly into the ESXi hypervisor and uses policy-based management (SPBM) to automatically apply performance and availability rules (like data mirroring or erasure coding) to virtual machines, simplifying storage provisioning and scaling. || Key Concepts __Software-Defined Storage: Virtualizes local storage from hosts into a unified pool. __Hyper-Converged Infrastructure (HCI): Combines compute (vSphere) and storage (vSAN) on the same x86 servers for simplified management. __Distributed Datastore: Aggregates disks (SSDs/HDDs) from all cluster nodes into one large datastore. __Policy-Based Management (SPBM): Defines storage requirements (performance, availability) in policies, which vSAN automatically enforces per VM. __Integration: Runs natively within the ESXi hypervisor, tightly integrated with vSphere features like vMotion, HA, and DRS. || How it Works __Disk Groups: Each host creates one or more disk groups, combining a flash cache device with one or more capacity devices (HDDs or SSDs). __Data Distribution: When a VM is deployed, vSAN breaks it into objects and components, distributing these across different hosts and disks in the cluster for performance and resilience. __Fault Tolerance: Policies define how many copies (replicas) or parity data (erasure coding) are kept, ensuring data availability even if a host or disk fails. || Benefits __Simplified Management: Single interface (vCenter) for compute and storage. __Scalability: Easily scale capacity and performance by adding hosts or disks. __Cost-Effective: Uses commodity x86 hardware and local storage. __High Performance: Delivers low-latency, high-throughput storage for demanding applications.
