High Performance and Flexible Storage Architecture
vSAN aggregates local or direct-attached data storage devices to create a single storage pool shared across all hosts in a vSAN cluster. A hybrid vSAN cluster uses flash devices for cache and magnetic drives for capacity. All-flash vSAN clusters use flash devices for both the cache and capacity. vSAN Express Storage Architecture uses NVMe-based TLC flash devices and high performance network interfaces. These architectures provide a flash-optimized, resilient shared datastore designed for the software-defined data center (SDDC).
Simplified Storage Configuration and Precise Management
vSAN eliminates the need for external shared storage and simplifies storage configuration through Storage Policy-Based Management (SPBM). Using virtual machine (VM) storage policies, you can define storage requirements and capabilities.
