vSAN: Hyperconverged Infrastructure
VMware vSAN is a hyperconverged infrastructure software for building scalable and high-performance storage with direct-attached storage devices, pooling cluster resources to create logical storage pools for virtual machines.
What is VSAN?
vSAN is VMware's hyperconverged infrastructure (HCI) software that allows organizations to build scalable and high-performance storage using direct-attached storage devices. It creates a distributed shared storage solution by pooling cluster resources to form logical storage pools for virtual machines.
Some key features of vSAN include:
- Software-defined storage - Storage capacity is flexibly defined in software using existing server-attached disk storage.
- Scalability - vSAN storage capacity can easily scale up or out with the growth of physical storage capacity.
- High availability - Data copies and hardware failures are handled gracefully to avoid downtime.
- Advanced data services - Data efficiency, encryption, quality of service and more.
- Tight integration - Tightly integrated with vSphere and the full VMware stack for simplified management.
- Lower TCO - Reduces overall storage costs by leveraging commodity hardware.
vSAN is well-suited for VDI environments, tier-2/3 workloads, ROBO deployments and DevOps that require simple, scalable and high-performance shared storage.
