Description

The Arista DCS-7130LBR-48S6QD-R is an advanced Layer 1 application switch designed for high-frequency trading, financial services, and data center environments requiring ultra-low latency and FPGA programmability. With 48x 10G SFP+ ports, 6x QSFP-DD uplinks supporting up to 96x 10G lanes via breakout, and dual VU9P-3 FPGAs, it delivers 2.4 Tbps throughput with sub-microsecond latency. The composable architecture with integrated Layer 1 crosspoint enables flexible port configuration for in-band switching or out-of-band telemetry, making it ideal for tap aggregation, real-time analytics, and custom FPGA applications.

FAQs

Q: What applications is the DCS-7130LBR-48S6QD-R best suited for?
A: This switch is optimized for high-frequency trading, financial markets, data center tap aggregation, network monitoring with streaming telemetry, and custom FPGA-accelerated applications requiring ultra-low latency and high bandwidth. The dual VU9P-3 FPGAs enable development of custom network processing, packet filtering, timestamping, and real-time analytics applications.

Q: Can the QSFP-DD ports be broken out into multiple 10G connections?
A: Yes, each of the 6x QSFP-DD ports can be broken out to 2x 40GbE or 8x 10GbE interfaces using appropriate breakout cables. This allows the switch to support up to 96x 10G lanes in total, providing exceptional port density and flexibility for high-bandwidth connectivity.

Q: Does this switch require any special licensing for Layer 3 routing features?
A: The DCS-7130LBR-48S6QD-R supports L2/L3 forwarding and advanced routing features through Arista EOS. For full routing capabilities including EVPN, VXLAN, Segment Routing, and advanced MPLS, an FLX License for Arista Fixed switches Group 4 is available, supporting up to 2M routes and over 24K ACL entries.

Q: What is the Layer 1 crosspoint feature and how does it work?
A: The Layer 1 crosspoint is a composable architecture that allows any front-panel port to be flexibly mapped 1:1 or mirrored to any platform component including the integrated switch, FPGAs, or other ports. Ports can be configured as in-band for switching and routing, or out-of-band for telemetry and FPGA processing, enabling diverse deployment scenarios without hardware changes.

Q: Is FPGA development supported and what tools are available?
A: Yes, Arista provides an FPGA Development Kit (FDK) that includes API documentation, sample code, and IP cores to streamline custom application development for the dual VU9P-3 FPGAs. This enables network engineers and developers to create specialized packet processing, timestamping, filtering, and analytics functions tailored to specific business requirements.
