Product overview

The Arista DCS-7050Q-16-F is a high-performance, fixed-configuration data center switch engineered for demanding cloud and enterprise networking environments. It combines 16x40GbE QSFP+ ports with 8x10GbE SFP+ ports in a compact 1RU form factor, delivering 1.28Tbps aggregate throughput and 960 million packets per second forwarding rate. The switch features wire-speed Layer 2 and Layer 3 forwarding with sub-microsecond latency (800-850ns on QSFP+, 800-1150ns on SFP+), enabling low-latency east-west traffic patterns critical for modern data centers. With 9MB dynamically allocated packet buffer, 128K MAC entries, and support for 16K IPv4 routes and 32K IPv4 host routes, it scales efficiently in large network deployments. The front-to-rear airflow design with N+1 redundant fan modules and dual 1+1 hot-swappable 460W AC power supplies ensures high availability. Running Arista EOS with advanced features including Zero Touch Provisioning, LANZ microburst detection, and comprehensive monitoring via sFlow and integrated packet capture, the 7050Q-16 supports modern network automation and visibility requirements.

Frequently asked questions

What is the switching capacity and forwarding performance of the DCS-7050Q-16-F?

The DCS-7050Q-16-F delivers 1.28 terabits per second (Tbps) aggregate switching capacity with 960 million packets per second (Mpps) forwarding rate. This non-blocking architecture supports wire-speed Layer 2 and Layer 3 forwarding across all 24 ports simultaneously, enabling high-throughput data center deployments without performance bottlenecks.

What latency does this switch provide for low-latency applications?

The 7050Q-16 provides latency of 800-850 nanoseconds (ns) on QSFP+ ports and 800-1150ns on SFP+ ports in cut-through forwarding mode. This sub-microsecond latency is critical for high-frequency trading, real-time analytics, and tightly-coupled HPC applications requiring deterministic packet delivery times.

How does the dynamic buffer allocation improve network performance?

The switch features a 9MB shared packet buffer pool with dynamic allocation that automatically directs buffer resources to congested ports. This intelligent congestion management prevents packet loss during traffic microbursts and ensures fair bandwidth distribution across ports without requiring manual buffer tuning.

What routing and forwarding table sizes does the 7050Q-16 support?

The switch supports 128,000 MAC address entries, 16,000 IPv4 routes, 32,000 IPv4 host routes, 8,000 IPv6 routes, and 8,000 multicast routes. These table sizes accommodate large-scale data center networks with thousands of connected devices and complex routing policies.

What redundancy and high-availability features are included?

The DCS-7050Q-16-F includes dual 1+1 hot-swappable 460W AC power supplies and four N+1 hot-swappable fan modules for N+1 redundancy. Arista EOS provides Stateful Fault Repair (SFR) for automatic recovery from software faults, and optional SSD storage enables advanced logging and packet capture for troubleshooting.

Is this switch suitable for cloud and virtualized environments?

Yes. The 7050Q-16 includes VM Tracer for host visibility, auto-VLAN provisioning, and Zero Touch Provisioning (ZTP) for rapid deployment in cloud environments. Advanced Event Management (AEM), sFlow monitoring, and integrated packet capture enable comprehensive visibility into virtual machine traffic patterns and network behavior.

What is the physical form factor and power consumption?

The switch is a compact 1RU form factor measuring 19 inches wide by 1.75 inches high by 16 inches deep, weighing 18 pounds. Typical power consumption is 192W at 25°C ambient with 50% load, with maximum power draw of 303W, making it efficient for high-density data center rack deployments.
