Which storage networking technology pools different types of storage from across the network into a single storage environment?

The idea being tested is storage virtualization: creating a single, shared pool from multiple storage resources that are spread across a network. In a hyper-converged setup, you take the disks (both fast SSDs for caching and larger HDDs for capacity) from several hosts and combine them into one distributed datastore that all hosts and virtual machines can use. This lets disparate storage devices be treated as one unified environment, managed as a single pool. This is exactly what vSAN does: it aggregates local disks from all ESXi hosts in a cluster into a single, shared datastore that spans the network, letting different storage types work together in one virtualized pool. NAS, SAN, and DAS don’t fit this scenario as neatly. NAS provides file-level storage over the network, SAN typically relies on a dedicated external storage array for block storage, and DAS is attached directly to a single server, not pooled across multiple systems.
