Description

Arista 7130 Series Ultralow-Latency Networking

The Arista 7130 Series is built for networks where every nanosecond counts. It includes Layer 1+ switches and FPGA-enabled platforms. Depending on the model, these systems can regenerate signals, patch ports remotely, multiplex packets, monitor traffic, and run custom packet processing.

Arista designed the series for financial trading, market data distribution, and other timing-sensitive work. The Connect models offer port-to-port latency as low as 4 nanoseconds on supported configurations. FPGA-enabled models run applications such as MetaMux and MetaWatch. Their performance depends on the platform and how you configure the application.

Key Features

Ultra-low-latency Layer 1 Switching

The 7130 Connect Series moves data between ports in as little as 4 ns on applicable models. Its Layer 1+ design regenerates signals without the usual packet buffering or queuing in the switching path. This keeps connections predictable and switching delay low.

FPGA-Based Network Processing

Selected 7130 platforms include field-programmable gate arrays (FPGAs). An FPGA is a chip that processes network traffic directly in hardware. Teams can use these platforms for multiplexing, filtering, monitoring, and custom network functions. The applications you can run depend on the hardware and development options.

Low-Latency Packet Multiplexing

MetaMux merges traffic from several input streams into one output stream. Arista documents an average latency of 39 ns on supported 7130L configurations. It suits exchange connectivity, order entry, and market data distribution. Actual latency depends on the platform and the application profile.

Network Monitoring and Packet Replication

Compatible platforms can tap traffic and replicate packets. MetaWatch adds traffic aggregation, packet capture, and buffering. Teams use these tools to study traffic patterns and find performance problems, with little effect on the traffic being monitored.

Precision Packet Timestamping

MetaWatch also provides high-resolution timestamps. It can attach timestamp data to captured frames and pull in traffic from several sources. Trading firms and network teams use this to measure packet timing and trace delays across their infrastructure.

Flexible Connectivity and Remote Configuration

The Connect Series handles signal regeneration, media conversion, port mirroring, and dynamic patching. Administrators can change supported port mappings through management interfaces. This makes network changes simpler and cuts down on trips to the data center.

Capabilities

The Arista 7130 Series offers different functions across its Layer 1+ and FPGA-enabled platforms, so you can pick the ones that match your connectivity, monitoring, and packet-processing needs. Layer 1+ connectivity links supported ports with minimal switching delay and predictable signal handling. For traffic aggregation, you can combine selected streams and deliver them to exchanges, capture systems, or other destinations.

For monitoring, compatible applications capture traffic and collect timestamp data for analysis. If you need specialized handling, supported FPGA applications can run multiplexing, filtering, and other custom tasks. The series also supports remote patching and media conversion, which lets you change compatible port mappings and connect supported interface types. When connection problems come up, port statistics and signal-quality data help you troubleshoot.

Key Specifications

Common Use Cases

Financial trading firms use the 7130 Series when network delay can affect order execution and market data handling. Compatible platforms offer low-latency exchange connectivity, combine traffic from multiple trading systems, and support precise packet timestamping.

Data center operators and network teams use it for traffic monitoring, packet capture, signal conversion, and dynamic patching. Teams that need specialized packet processing can look at the FPGA-enabled models. The right choice depends on your interface speeds, port count, application needs, and latency targets.

Deployment Scenarios

• Exchange connectivity: Connect trading systems to exchange-facing infrastructure with a suitable low-latency platform.

• Market data distribution: Aggregate or replicate market data for trading and analytics systems.

• Order aggregation: Use MetaMux on supported FPGA platforms to merge multiple order-entry streams.

• Traffic monitoring: Deploy MetaWatch for packet capture, timestamping, and traffic analysis.

• Remote patching: Change supported port mappings without moving cables in the data center.

• Custom packet processing: Evaluate FPGA-enabled models for specialized filtering, multiplexing, or other supported applications.

Why Choose Netmate IT for Arista 7130 Series Solutions?

The 7130 Series covers a lot of ground, and the right model is not always obvious. A 16-port Connect switch and an FPGA platform running MetaMux solve very different problems. Picking the wrong one can mean wasted budget or missed latency targets.

Netmate IT helps you sort this out before you buy. We start with what you need to do, such as connect to an exchange, merge order flow, or capture and timestamp traffic. Then we match that to the right Arista platform, check that the interface speeds and applications work with your setup, and plan how it fits into your current network.

If you are still comparing options, send us your requirements, and we will point you to the models worth a closer look.

Frequently Asked Questions

1. What is the Arista 7130 Series used for?

Mostly for trading networks. Firms use it to connect to exchanges, distribute market data, and monitor traffic where timing matters. Some models are Layer 1+ switches. Others have FPGAs that run applications for specialized packet processing.

2. How fast is the Arista 7130 Series?

It depends on the model and what you run on it. The Connect Series moves data from port to port in as little as 4 ns on the 16- and 48-port models. The documented 96-port model runs at 6 ns. MetaMux, which merges multiple streams into one, averages 39 ns on supported 7130L setups. These two numbers measure different jobs, so don’t compare them directly.

3. How does the 7130 Series help with high-frequency trading?

It cuts the time your traffic spends inside the network. A Connect switch links your trading systems to the exchange with very little delay. MetaMux can merge several order-entry streams into one. MetaWatch can timestamp packets and capture market data, so you can see where delays happen. Which of these you need depends on your setup.

4. What is the difference between Connect and FPGA-enabled models?

Connect models are built for fast, simple connectivity. They handle signal regeneration, media conversion, and remote patching. FPGA-enabled models add programmable applications such as MetaMux and MetaWatch. If you mainly need a fast link, start with Connect. If you need to process or analyze packets on the device, look at the FPGA models.

5. Can the 7130 Series monitor traffic and filter packets?

Yes, on supported platforms. MetaWatch handles monitoring and packet capture. Other FPGA applications add filtering and connection sharing. What you get depends on your hardware, application, and software version, so check the datasheet before you decide.
