Which storage architecture provides block-level storage to servers over a network?

Explanation:
Block-level storage over a network is provided by a Storage Area Network. In a SAN, servers access storage as raw blocks (LUNs) over a dedicated network, so the host can partition and format the space with its own filesystem and manage it as a disk just like DAS, but shared across multiple servers. This contrasts with NAS, which serves files over the network using file protocols (NFS/SMB), and with object storage, which stores data as objects accessed via APIs rather than as block devices. DAS is directly attached to a single server and isn’t provided over a network.
