Marketing Information | Cisco Nexus 3000 Series Switches overview 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 of switches provides line-rate Layer 2 and 3 performance and is suitable for Top-of-the-Rack (ToR) architecture. This series of switches has established itself as a leader in High-Frequency Trading (HFT), High-Performance Computing (HPC), and big data environments by pairing high performance and low latency with innovations in performance visibility, automation, and time synchronization. Cisco Nexus 3500 platform overview The Cisco Nexus 3500 platform further extends the leadership of the Cisco Nexus 3000 Series by including the innovative Cisco® Algorithm Boost (or Algo Boost) technology. Algo Boost technology, built into the switch Application-Specific Integrated Circuit (ASIC), allows the Cisco Nexus 3500 platform to achieve exceptional Layer 2 and 3 switching latencies of less than 200 nanoseconds (ns). In addition, Algo Boost offers several innovations in latency, forwarding, and performance visibility capabilities: - Three configurable modes for low latency
- Normal mode: This mode is excellent for environments needing low latency and high scalability. In this mode, latencies as low as 250 ns can be paired with the higher of the Layer 2 and 3 scaling values listed later in this document, in Table 6 and 7.
- Warp mode: For those customers with smaller environments who demand the lowest latencies possible, warp mode consolidates forwarding operations within the switch ASIC, lowering latency by up to an additional 20 percent compared to normal operation. In this mode, latencies as low as 190 ns can be paired with the smaller of the Layer 2 and 3 scaling values listed later in this document, in Table 8.
- Warp SPAN: In some environments, a stream of traffic entering one port simply needs to be copied to a list of outgoing ports as quickly as possible without processing or modification. The Cisco Nexus 3500 platform's warp SPAN capability allows all traffic entering a single port on the switch to be replicated to any number of destination ports at latencies as low as 50 ns.
- Hitless Network Address Translation (NAT): In many financial trading environments, trade orders must be sourced from the IP space of the provider, requiring NAT at the border between networks. The Cisco Nexus 3500 platform can perform NAT for IPv4 unicast routed packets without incurring any additional latency. The Cisco Nexus 3548-X and 3524-X Switches introduce multicast NAT to the platform's capability. Customers hosting co-locations will find this feature useful in simplifying their network topologies and concealing details of their data centers.
- Latency monitoring: When nanoseconds matter, switch latency monitoring is essential to your company's profitability. The Cisco Nexus 3548-X and 3524-X enable users to finely control their environments to increase network performance. Customers can identify latency on a specific egress port through the Command-Line Interface (CLI) and export this information to a file. The programmability of the Cisco Nexus 3548-X allows users to use this information in real time.
