In the rapidly evolving fields of high-performance computing (HPC) and artificial intelligence (AI), choosing the right interconnect for your compute nodes is critical. The two most prominent technologies—InfiniBand and Ethernet—have distinct strengths and are increasingly important for meeting the ultra-low-latency, high-throughput demands of modern computing.

In the world of High-Frequency Trading (HFT), milliseconds matter. Network engineers tasked with building HFT environments need to select switches that not only provide ultra-low latency but also support high-speed ports and critical Layer 3 features like QoS and VLAN tagging. This post will explore three of the best Arista switches tailored for HFT environments and discuss key IEEE protocols and RFCs essential for designing high-performance trading networks.

Key Requirements for HFT Switches:

Elevate Your Network Efficiency with the DCS-7050SX3-48YC12-F: The Ultimate Solution for Tier 2 ISPs and Service Providers

At Terabit Systems, we're excited to announce the availability of the DCS-7050SX3-48YC12-F, a game-changer in the realm of networking hardware designed to meet the evolving needs of Tier 2 ISPs and service providers. This cutting-edge switch from the esteemed brand Arista Networks is poised to revolutionize your network infrastructure, delivering unmatched performance and reliability.

If you need to keep legacy copper NICs in place while allowing for increased bandwidth through the 100G ports The Arista DCS-7280TR-48C6 is one we have no problem recommending to our clients.

The Arista DCS-7050SX and DCS-7050QX series are both high-performance, low-latency networking switches designed for use in data centers. While both series offer similar features and capabilities, there are some key differences that make one better suited for certain applications and environments.

The Arista 7200 series switches are a top-of-the-line offering from the networking equipment manufacturer. These switches are designed for use in high-performance, mission-critical environments, such as data centers and large enterprise networks.

Finding the Right Arista Switch For You: 7060CX-32S VS.7260CX3-64

Last year, we mentioned some recent strides Arista has made to close the gap with long-time routing juggernauts, Cisco and Juniper.

And while the company has continued to sport more and more blue chips in the networking department, we’d be lying if we told you their arena isn’t still the data center – or that having that reputation in a year like 2020 is a bad thing.

Once known primarily as a data center and network switch vendor, Arista is now making considerable headway into the router market. Armed with its cloud-streamlined EOS platform and headed by a company CEO that was just crowned the best in the business, there’s a lot to like in Arista’s router catalog--particularly with the 100G capable Arista 7280R series.

Current Cost Per Port Analysis for Secondary Market Juniper and Arista 10G based switching

In a dynamic, price changing market, this is not exactly an apples to apples comparison, however, here’s a market snapshot of cost per port on our historically best-selling 10G switching options from Arista and Juniper. Keep in mind that an Arista DCS-7050S-52-R may run at 800 nanoseconds (ns) to 1.2μs (microseconds) latency, while a DCS-7150S-24-R has a latency greater than 350 nanoseconds.

What makes solid performing hardware? You’d be correct in guessing that it might start with solid hardware. When Arista mentioned in their whitepaper* that the 7150S included an onboard high precision “Oven-Controlled Crystal Oscillator” (OXCO), I was compelled to find out what this gadget accomplishes on the DCS-7150S.
