LAN, WAN, and SAN – What’s the Difference?![]() LAN, WAN, and SAN – What’s the Difference?Modern IT infrastructure relies on different types of networks to handle data, storage, and communication. Three of the most common terms—LAN, WAN, and SAN—each serve a distinct purpose in business operations. At IronLAN, we design all three from the ground up to deliver maximum performance, security, and control. What is a LAN?A Local Area Network (LAN) connects devices within a limited area such as an office, building, or campus. It enables fast file sharing, internal application access, and centralized resource use.
What is a WAN?A Wide Area Network (WAN) connects multiple LANs across distant geographic locations. WANs enable branch offices, remote teams, and data centers to securely communicate over the internet or private links.
What is a SAN?A Storage Area Network (SAN) provides fast, block-level access to shared storage across servers. SANs are used in environments where storage performance, uptime, and scalability are mission-critical.
Why Choose IronLAN?We don’t just supply hardware—we design intelligent network infrastructure that aligns with your mission. Whether you're building a secure LAN, scaling a national WAN, or deploying a SAN for high-throughput workloads, IronLAN delivers precision-engineered solutions built to last.
