Which type of connection across the network does a SAN allow for multiple servers to access an unlimited amount of storage devices?

'Any-to-many' implies a single source reaching multiple fixed targets, which does not capture the full bidirectional fabric access model of a SAN.

'Many-to-any' only describes multiple servers reaching any storage device and ignores the symmetric, fully-meshed nature of SAN fabric connectivity.

A Storage Area Network uses a dedicated high-speed fabric (Fibre Channel or iSCSI) that decouples storage from individual servers and creates a shared pool where any host can reach any storage target. This any-to-any model is the defining architectural characteristic of a SAN, enabling flexible provisioning, load balancing, and scalability across an unlimited number of servers and storage devices.

'Any-to-one' describes multiple sources converging on a single destination, which contradicts the SAN design goal of accessing unlimited storage devices.

'One-to-any' describes a single server reaching any storage device, which omits the multi-server side of the SAN topology.

'One-to-one' is a direct dedicated connection model, the opposite of the shared-fabric, multi-host architecture a SAN provides.
