Storage Area Networks (SANs) are specialized networks designed to provide high-speed, block-level access to storage devices. In this episode, we explain how SANs differ from traditional file-based network storage, such as NAS, and how they enable critical enterprise applications to achieve high I/O performance. You’ll learn about SAN protocols like Fibre Channel and iSCSI, as well as the hardware components that make up a SAN, including HBAs, SAN switches, and target storage arrays.

We also discuss zoning, LUN masking, and how SANs are used in server clusters and virtualized environments. SANs are commonly found in environments that require fast access to large databases, backup systems, or virtual machines. Understanding how SANs function and how to troubleshoot them is important for network technicians supporting enterprise environments. Whether you're studying for the exam or planning data center storage, this episode is a must-listen.
