Storage Area Network
A Storage Area Network (SAN) is a high-speed network that provides block-level access to consolidated data storage, typically using Fibre Channel or iSCSI protocols. It connects servers to storage devices like disk arrays and tape libraries, enabling centralized management and efficient data sharing across multiple servers. SANs are designed for high performance, scalability, and reliability in enterprise environments.
Developers should learn about SANs when working in large-scale enterprise or data center environments that require high-performance, shared storage for applications like databases, virtualization, and big data processing. It's essential for roles involving infrastructure management, cloud computing, or systems architecture where centralized storage and disaster recovery are critical. Understanding SANs helps optimize data access, improve availability, and support scalable storage solutions.
