Data Center Switch Low Latency

Overview CX-N series cloud switches are next generation high-performance, high-density, low-latency ethernet switches for cloud data center. Based on advanced hardware architecture, CX-N switches provide high-density 25GE/40GE/100GE/ 200GE/400GE ports in compact box design and integrate rich data center features. Users can use CX-N series cloud switches to build elastic, virtual, and high-quality data center networks, meeting the network requirements of data centers in the cloud computing era. CX-N series cloud switches are ideal for spine and leaf layers of CLOS networks, helping enterprises and operators to build data center network platforms for the cloud computing era, and can also be used as core or aggregation of campus networks.

Highlights

◼ Port-to-port forwarding latency as low as 400ns

◼ Compact 1RU/2RU fixed units, high port density with multi-speed combination
