N3K-C3548P-XL Nexus 3548-XL 48 ports SFP+ core network Switch N3K-C3548P-10GX

The Cisco Nexus® 3000 Series Switches are a comprehensive portfolio of 1, 10, and 40 Gigabit Ethernet switches built from a Switch-on-a-Chip (SoC) architecture. Introduced in April 2011, this series provides line-rate Layer 2 and 3 performance and is ideal for Top-of-the-Rack (ToR) architecture. These switches excel in High-Frequency Trading (HFT), High-Performance Computing (HPC), and big data environments by combining high performance and low latency with innovations in performance visibility, automation, and time synchronization.
