Description

The Arista DCS-7388X5-80C-24DR-F is a high-performance modular data centre switch delivering 25.6 Tbps throughput with 80 ports of 200GbE and 24 ports of 400GbE QSFP-DD in a compact 4RU chassis. Built on a single high-capacity packet processor, it provides ultra-low latency of 825ns and 114MB packet buffer, making it ideal for hyperscale cloud, AI/ML workloads, and large-scale spine-leaf architectures. The system includes the 7388X5 base bundle with redundant AC power supplies, supervisor module, switch card, and front-to-rear airflow for efficient data centre cooling.

FAQs

Q: What deployment scenarios is the DCS-7388X5-80C-24DR-F suited for?
A: This switch is designed for hyperscale data centre spine-leaf architectures, AI/ML cluster networking, and high-radix cloud environments requiring a mix of 200G and 400G connectivity with ultra-low latency and high throughput.

Q: What is included in the system bundle?
A: The bundle includes the 7388X5 chassis, redundant AC power supplies, supervisor module with management ports, 7388X5-SC switch card, cooling fans with front-to-rear airflow, and eight interface module slots pre-configured for 80x 200G and 24x 400G ports.

Q: Can the port configuration be changed or expanded?
A: Yes, the 7388X5 is a modular system with 8 hot-swappable I/O module slots. You can reconfigure the interface modules to support different port densities and speeds (100G/200G/400G) based on your network requirements, up to a maximum of 128 ports of 200G or 64 ports of 400G.

Q: What software licensing is required?
A: Base Arista EOS functionality is included with the switch. Advanced routing features require an EOS Enhanced license, while BGP-EVPN and VXLAN capabilities require the FlexRoute (FLX) Lite license. CloudVision for advanced automation and visibility is available as a separate subscription.

Q: What is the typical power consumption?
A: Power consumption varies based on configuration and load. The system is designed for efficient operation in data centres, with redundant AC power supplies providing sufficient capacity for all modules and optics. Exact power specifications depend on the installed optics and system load.
