Flexibility, scalability, agility. These are capabilities that everyone claims in the industry. How do you actually differentiate which company’s solution is the best? Instead of boring you with more buzz words, let me show you who really owns the crown for the best data center switches: Nexus 9000 Switches.

Nexus 9000 data center switches are the best in its category based on numerous tests. The data speaks for itself.

Spirent Selected to Conduct Record-Breaking Test of Cisco Data Center Core Switch

“…This test broke new records for Network World, with 10,000 unique IPv4 multicast group addresses, nearly twice as many groups than in any previous Network World project.” – David Newman, Network World

 Cisco Nexus 9516 data center switch aces a grueling high-density stress test

Our test of a Cisco Nexus 9516 with 1,024 fully loaded 50G Ethernet ports – the highest density core-switch test ever done by Network World – found it capable of handling the strain without dropping a packet – David Newman, Network World

Cisco Nexus 9516: Scaling 100G Performance to New Heights

Seven sets of rigorous benchmark test results demonstrated high performance and versatility in every case:

  • Zero frame loss in all tests, covering unicast, multicast, Layer-2, Layer-3, and routing across all 128 100G Ethernet ports
  • Low latency and jitter across test cases
  • Loss-free performance when forwarding to BGP and BGP-MP routes using IPv4 and IPv6 traffic Loss-free performance when forwarding to more than 520,000 IP multicast routes
  • Support for a variety of 100G Ethernet transceiver types

Cisco Nexus 9508: A New High-Water Mark For 100G Performance

With 10G and 40G Ethernet speeds now standard in data center ToR switches, there’s no question that 100G Ethernet has become the de facto core switch technology. There is a question, however, as to how high this relatively new flavor of Ethernet can scale. Cisco Systems has a simple answer: As high as you’d like to go.

  • A series of rigorous stress tests demonstrated high performance and scalability in every case:
  • Zero frame loss in test cases covering unicast, 1-to-N multicast, N-to-N multicast, Layer-2, Layer-3, and routing across all 256 100G Ethernet ports
  • Low latency and jitter across test cases
  • Loss-free performance when forwarding to BGP and BGP-MP routes using IPv4 and IPv6
  • Loss-free forwarding to more than 1 million IP multicast routes, a new record, in both Layer-2 and Layer-3 configurations
  • Wire-speed performance across all Layer-2 and Layer-3 multicast test cases

Cisco Nexus 9508: A New Speed Record in Data Center Switching

Let’s cut right to the chase: The Cisco Nexus 9508 is the densest, fastest data center switch we’ve ever tested. Even in the rarified world of data center core switches, Cisco’s new Cloudscale Technology ASICs moved more traffic faster, and with lower latency and jitter, than any other switch we’ve evaluated.

The Cisco Nexus 9508 proved its mettle across every high-stress test case. Among the major findings:

  • Virtual line-rate performance in every test, regardless of frame size. In previous tests at this scale using mechant-silicon ASICs, the switch could not handle smaller frame sizes at line rate without loss
  • Record low latency and jitter across all test cases
  • Zero frame loss across all test cases covering unicast, multicast, Layer-2, Layer-3, and routing across all 256 100G Ethernet ports
  • Zero frame loss in N-to-N multicast test cases, both in Layer-2 and Layer-3 configurations. In contrast, merchant silicon ASICs require gaps in test traffic to perform without loss
  • 100G Ethernet power consumption as low as 23 watts per port
  • Loss-free performance when forwarding to BGP and BGP-MP routes using IPv4 and IPv6
  • Loss-free forwarding to more than 1 million IP multicast routes*OIFs/OILs in Layer-2 and Layer-3 configurations
  • Wire-speed performance across all Layer-2 and Layer-3 multicast test cases

Miercom: Speeding Application in Data Center Networks

“With the real-world traffic profiles, our testing results show that the Cisco Nexus 92160YC-X and Nexus 9272Q switches outperformed the Arista 7280SE-72 switch for congestion handling. The Arista 7280SE-72 switch has much deeper buffer than the Cisco switches, but with the built-in intelligent buffer management capabilities, both Cisco switches demonstrated clear advantage in flow completion time for small/medium flows over the Arista 7280SE-72 switch and provided the same or similar performance for large-size flows, which resulted in overall higher application performance.”
