Description

The Arista DCS-7170-32CD-R is a powerful, fixed configuration switch built for high-performance data centers. It features 32 QSFP100 ports for 100 Gbps connectivity and supports breakout configurations to enable 40G, 50G, 25G, or 10G links. Moreover, it offers rear-to-front airflow, making it suitable for racks where the cooling layout demands air intake from the front and exhaust out the rear. With a switching capacity of 6.4 Tbps and forwarding rate of up to 2.4 Bpps, this switch delivers wire-speed L2/L3 performance. Because it includes dual AC power supplies and redundant fan modules, it ensures uptime and reliability in production settings.

Key Features & Benefits (Arista DCS-7170-32CD-R)

• Flexible Port Speeds: Supports breakout modes so you can adapt between 100G, 40G, 25G, or 10G per port depending on workload and cabling.
• High Capacity & Low Latency: Delivers 6.4 Tbps switching with forwarding rates up to 2.4 Bpps, plus latency around 800 ns for fast packet delivery.
• Efficient Cooling Design: Rear-to-front airflow paired with hot-swappable fans helps maintain optimal temperature in tightly packed data center racks.
• Reliable Power Architecture: Comes with 2× PWR-747AC power supplies, which are hot-swappable, so you maintain power stability even during maintenance.
• Solid Buffering & Traffic Management: Built-in ~20 MB of packet buffering helps manage brief bursts of traffic without packet loss.

Use Cases:

• Data Center Spine/Leaf Fabric: Perfect choice for backbone or spine layer where dense 100G connections are essential.
• High-Throughput Cloud Networks: Handles heavy east-west traffic between server clusters or pods.
• Telecom & Carrier Deployments: Offers reliable throughput for backbone or metro use where performance matters.
• Upgrade Paths: Works well when moving up from 10G/25G infrastructure toward 100G as capacity grows.
