What is the latency performance of this switch?

It provides ultra-low deterministic latency from 350ns across all ports for L2/3/4 wire-speed forwarding. This is complemented by IEEE 1588 PTP high precision clock option, making it suitable for HFT and time-sensitive applications requiring sub-microsecond precision.

What is the switching capacity and forwarding rate?

The DCS-7150S-64 offers 1.28 Tbps switching capacity and 960 Mpps forwarding rate, ensuring non-blocking performance. It supports up to 64K next hops, 18K IPv6 routes, and advanced features like 32-way ECMP for efficient high-throughput networking.

What management features does it support?

Powered by Arista EOS, it includes ZTP, sFlow RFC3176, VMTracer, Advanced Event Management, and DANZ mirroring. The multi-core x86 CPU with 4GB DRAM and 2GB flash allows running user applications in VMs for enhanced automation and monitoring.

What are the physical and power specifications?

It's a 1RU rack-mount chassis with front-to-rear or rear-to-front airflow options and 2x hot-swappable AC PSUs. Packet buffering is 9.5MB dynamic, with optional 50GB SSD, ensuring reliability and space efficiency in datacenters.

Does it support advanced routing protocols?

Yes, it supports RIPv2, OSPF, OSPFv3, BGP, MP-BGP, ISIS, BFD, and VRF, alongside 70K IPv4 routes. This enables robust L3 functionality for complex datacenter overlays and multi-tenant environments.
