Arista 7130 Hardware

7130 Connect Series devices implement a Layer 1+ switch, host a quad-core x86 management platform and RAM. The devices are widely deployed for low-latency market data replication, reliable, cost-effective tapping, test lab automation and remote data center patch automation. Layer 1+ switches implement a rich set of operational functionality, deeply integrated with the operating system, including counters, LLDP, tcpdump, optical transceiver management and monitoring, and streaming telemetry.

7130B Series devices provide a high density Layer 1+ switch, offering up to 256 front panel connections. To reduce cabling and maintain a compact form factor, each of the 32 x QSFP-DD ports carry up to 8 x 10G connections. The system hosts an Intel Tofino P4 programmable switch chip which enables a full switching feature set on any port. In addition to standard L2 and L3 features, the integrated switch chip offers a choice of forwarding profiles in common with the 7170 Series, as well as the possibility to deploy fully customized pipelines. The switch also provides a complete set of counters and streaming telemetry for both switched and pure Layer 1 paths. The high radix 7130B enables customers to collapse multiple tiers of lower density Layer 1 devices to scale-out applications such as low-latency market data replication, centralized tapping, test lab automation, and remote data center patch automation.

7130L Series devices are optimized for 10G applications and host a Layer 1+ switch, a Xilinx FPGA, 32G of FPGA RAM, a precision OCXO oscillator, a quad-core x86 CPU for management and applications, with 8G CPU RAM, as well as a two-port 10G NIC. There are options for 48 or 96 ports, though the FPGA connectivity is limited to a minimum of 58 ports (60 on the 48-port variant).

7130L Series supports the L or LB development standard and compatible applications. The LB features a larger FPGA with a faster speed grade for minimizing latency. Key use cases include precision, lossless, tap/aggregation and low latency switching.

Arista 7130E Series devices contain up to three high-performance Xilinx FPGAs, in a single system, with dense serial and parallel interconnects giving the lowest-latency FPGA-FPGA communication possible. The integrated Layer 1+ switch allows for each FPGA to receive a copy of any stream, and for inter-FPGA connectivity to be tapped and timestamped. Arista 7130E Series devices have 48 front-panel ports running at 10G, a TCXO oscillator, a quad-core x86 CPU, and 8G CPU RAM.

Arista 7130E Series devices are purpose built to host applications with dense FPGA requirements implemented for the EH Central and EH Leaf development standard. Typical applications include trading algorithms, where parts of the algorithm such as pre-trade checks are implemented in one FPGA, and parts of the algorithm e.g. the trading algorithm, are implemented in another FPGA. The 7130E Series does not implement any FPGA RAM, in favor of fitting more FPGAs.

Arista 7130LBR Series devices are fully composable, single device solutions hosting a combination of Layer 1 switching, dual LB- standard FPGAs, a high specification switching chip from the 7280R3 family, and an eight-core x86 control plane. The 7130LBR can be used to consolidate the duties of multiple separate devices, eliminating cabling and inter-device latency, while enabling local offload of functions between the key forwarding components. Complex applications such as pre-trade risk checks and smart order routing can be split across the 7130LBR’s multiple FPGAs to minimize latency and maximize available hardware logic. An all-in-one trading and monitoring solution can be realized by combining MetaWatch’s picosecond-level timetamping with a custom trading application on a single box. The 7130LBR’s unique architecture is well suited to a variety of high performance in-network applications.
