The HP A5120G EI Switch Series are Gigabit Ethernet switches that support static Layer 3 routing, diversified services, and IPv6 forwarding and provide up to four 10-Gigabit Ethernet (10 GbE) extended interfaces. Unique Intelligent Resilient Framework (IRF) technology creates virtual fabric by virtualizing several switches into one logical device, which increases network resilience, performance, and availability while reducing operational complexity.
