Zoning is a technology used in B-series SAN switches to control and prevent communication between unauthorized devices within a SAN fabric. By creating zones, administrators can define which devices (like servers and storage arrays) can communicate with each other, enhancing security and reducing the risk of unauthorized access. This approach is fundamental in maintaining secure and organized SAN environments. HPE Storage References: * HPE B-Series SAN Switches * HPE SAN Solutions and Zoning
