Product overview

The Arista 7050SX-64 is a high-performance Layer 3 data center switch delivering 2.56 Terabits per second switching capacity with 48 SFP+ 10GbE ports and 4 QSFP+ 40GbE uplink ports. Engineered for cloud-scale deployments, it provides ultra-low latency of 550 nanoseconds in cut-through mode and forwards up to 1.44 billion packets per second. The switch features 288K MAC entries, 144K IPv4 routes, and 208K IPv4 host routes with support for 64-way ECMP and MLAG for resilient multi-pathing. Equipped with a high-performance x86 CPU, up to 8GB DRAM, and 16MB dynamic buffer allocation, it supports VXLAN, OpenFlow, and DirectFlow for modern cloud networking. The compact 1RU form factor with redundant hot-swap power supplies and front-to-back airflow ensures efficient deployment in dense data center environments. Ideal for enterprise networks, high-frequency trading, and cloud infrastructure requiring wire-speed Layer 2/3 forwarding with advanced telemetry and network virtualization capabilities.

What is the maximum throughput of the Arista 7050SX-64?

The 7050SX-64 delivers 2.56 Terabits per second switching capacity with a forwarding rate of 1.44 billion packets per second. This enables wire-speed Layer 2 and Layer 3 forwarding across all 52 ports simultaneously without performance degradation.

What is the latency performance in cut-through mode?

The switch achieves ultra-low latency of 550 nanoseconds in cut-through mode, making it suitable for latency-sensitive applications including high-frequency trading, real-time analytics, and financial services. This deterministic performance is maintained across all ports.

How many MAC addresses and routes can the switch support?

The 7050SX-64 supports 288K MAC address entries, 144K IPv4 routes, and 208K IPv4 host routes. This capacity enables large-scale deployments with thousands of connected devices and complex routing topologies without table exhaustion.

Does the switch support VXLAN and network virtualization?

Yes, the 7050SX-64 supports VXLAN, VM Tracer, OpenFlow, DirectFlow, and eAPI for advanced network virtualization and cloud networking. It runs Arista EOS with programmable access via Python and C++, enabling custom automation and telemetry.

What redundancy and load balancing features are available?

The switch supports 64-way ECMP routing and 64-way MLAG for active-active L2/L3 multi-pathing. It includes redundant hot-swap power supplies, hot-swappable fans, and 16MB dynamic buffer allocation for congestion management and high availability.

What is the power consumption per 10GbE port?

The 7050SX-64 consumes approximately 1.2W per 10GbE port, making it energy-efficient for large-scale deployments. Redundant power supplies with hot-swap capability ensure continuous operation during maintenance or power supply failures.
