The term "storage network" typically refers to a Storage Area Network (SAN), which provides block-level storage access. Dell PowerStore is a unified platform that supports multiple protocols, including block protocols (iSCSI, FC) and file protocols (NFS, SMB). Both iSCSI and FC are used for SANs. However, iSCSI (Internet Small Computer System Interface) operates over standard TCP/IP Ethernet networks. This aligns directly with the IP-based architecture of modern data centers and the PowerStore platform itself, which uses IP for management and replication. Therefore, iSCSI is a primary protocol for creating a storage network with PowerStore.

A. FC: While PowerStore supports Fibre Channel (FC), it requires a dedicated, separate physical network (a fabric), unlike iSCSI, which leverages standard Ethernet infrastructure.

B. NFS: This is a file-level protocol for Network Attached Storage (NAS), which provides file-system access over a network, not block-level access characteristic of a SAN.

C. SMB: This is a file-level protocol, primarily used by Windows for Network Attached Storage (NAS), and does not provide the block-level access of a SAN.

This document states, "For block storage, the system supports the FC, iSCSI, and NVMe/FC protocols. For file storage, the system supports the NFS and SMB protocols," confirming the supported protocols and their classification.

2. Dell Technologies. (June 2023). Dell PowerStore: Networking Guide. Technical Document. Page 10, Section: "Network types". This guide explicitly defines the "Storage network" as the network that "carries iSCSI data traffic between the host and the PowerStore system," distinguishing it from networks for file or replication traffic.

This academic article defines SANs as block-service storage systems, with iSCSI and Fibre Channel as primary examples, while NAS systems are defined as file-service systems using protocols like NFS and SMB/CIFS.
