VMware vSAN, which stands for VMware Virtual SAN, is a software-defined storage solution offered by VMware. It is a component of VMware's vSphere virtualization platform and is designed to provide highly scalable, high-performance shared storage for virtual machines (VMs) in a vSphere environment.
vSAN allows you to pool together the direct-attached storage devices (such as hard drives or solid-state drives) from multiple servers in a vSphere cluster and create a distributed storage infrastructure. By aggregating the storage resources from these servers, vSAN creates a shared storage pool that can be utilized by VMs running on those servers.
Key features and benefits of VMware vSAN include:
Hyperconverged Infrastructure (HCI): vSAN is a key component of VMware's HCI solution. It combines compute, storage, and virtualization resources into a single software-defined platform, simplifying data center operations and reducing hardware costs.
Highly scalable and elastic: vSAN allows you to scale storage capacity and performance as your needs grow. You can easily add or remove drives or hosts from the vSAN cluster without disruption.
Enterprise-grade features: vSAN includes a wide range of enterprise-class features such as deduplication, compression, erasure coding, and RAID protection to ensure data integrity, performance, and efficiency.
Built-in data protection: vSAN offers integrated data protection capabilities, including snapshots, clones, and remote replication, enabling efficient backup and disaster recovery solutions.
Integration with vSphere: vSAN seamlessly integrates with VMware's vSphere platform, providing a unified management experience. You can manage storage policies, monitor performance, and troubleshoot storage-related issues through the vSphere web client.
Hardware-agnostic: vSAN is hardware-agnostic, allowing you to use a variety of industry-standard server hardware components. This flexibility gives you the freedom to choose hardware that fits your requirements and budget.
