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.
