Description
DCS-7280CR3-32D4-F Arista Networks 7280CR3-32D4 Ethernet Switch - Manageable - 100 Gigabit Ethernet, 400 Gigabit Ethernet - 100GBase-X - 3 Layer Supported - Modular - Power Supply - 851 W Power Consumption
- Model: Arista DCS-7280CR3-32D4-F
- Series: Arista 7280R3
- Form Factor: 1 RU (Rack Unit)
- Airflow: Front-to-back airflow (denoted by the "F" in the model number).
Port Configuration:
- 32 x 100GbE QSFP28 ports:
- Each QSFP28 port can support 100GbE, 40GbE, or breakout configurations such as 4x25GbE or 4x10GbE for flexibility.
- 4 x 400GbE QSFP-DD ports:
- Each port can support 400GbE or be broken out into smaller port speeds, such as 4 x 100GbE, providing future-proofing for growing bandwidth demands.
Performance:
- Switching Capacity: 12.8 Tbps (Terabits per second).
- Forwarding Rate: 5.7 Bpps (Billion packets per second).
- Latency: Ultra-low latency, suitable for environments requiring fast and consistent network performance.
Buffering:
- Packet Buffer Memory: 64 MB dynamically allocated per port group, designed to handle traffic bursts and ensure smooth performance in congested environments.
