Cisco Nexus 3548 and 3524 Switches

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.

◦ 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 6.

◦ 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.

●

Active buffer monitoring: Even on the lowest-latency switches, data packets can incur a millisecond or more

of latency during periods of congestion. Today’s switches do not adequately inform administrators about the

presence of this congestion, leaving them unaware and hindered in their ability to address the conditions

causing suboptimal performance. Previous buffer utilization monitoring techniques were based entirely on

software polling algorithms with polling intervals higher than 100 ms, which can miss important congestion

events. In contrast, Algo Boost accelerates the collection of buffer utilization data in hardware, allowing

sampling intervals of 10 ns or less.
