Frequently asked questions

What is the total switching capacity and port configuration of the 7050SX3-48YC12?

The Arista 7050SX3-48YC12 delivers 25.6Tbps of full-duplex, non-blocking switching capacity. It features 48 ports of 25GBASE-SR/LR (supporting 25Gbps per port) and 12 ports of 100GBASE-SR4/LR4 (supporting 100Gbps per port). This configuration enables wire-speed forwarding across all ports simultaneously, making it ideal for high-density leaf deployments in hyperscale data centers.

What latency does this switch achieve, and why is it important for modern data centers?

The 7050SX3-48YC12 achieves sub-microsecond latency with deterministic, predictable performance. This ultra-low latency is critical for east-west traffic in cloud environments, containerized workloads, and HPC clusters where microsecond delays compound across thousands of server-to-server communications. Deterministic performance ensures consistent application response times and prevents tail latency issues.

Which network operating systems and protocols does the 7050SX3-48YC12 support?

The switch runs Arista EOS (Extensible Operating System), which supports BGP EVPN, VXLAN, and multi-tenancy isolation. It includes extensive automation APIs (eAPI, gRPC) for integration with orchestration platforms like Kubernetes and Terraform. Supports standard protocols including LACP, LLDP, SNMP, and sFlow for monitoring and telemetry.

Is the 7050SX3-48YC12 suitable for NVMe-over-Fabrics (NVMe-oF) storage deployments?

Yes. The switch's ultra-low latency, high port density, and non-blocking architecture make it ideal for NVMe-oF deployments. The 25GbE and 100GbE ports support RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE), enabling high-speed, low-latency storage traffic without CPU overhead. Deterministic performance prevents congestion-related packet loss.

What power consumption and thermal characteristics should be expected?

The 7050SX3-48YC12 is engineered for power efficiency relative to port density. Typical power consumption ranges from 1,200–1,500W under full load, depending on optics and configuration. The switch supports hot-swappable power supplies and fans with redundancy options. Thermal design accommodates standard data center cooling infrastructure with front-to-back airflow.

How does the 7050SX3-48YC12 integrate into existing HPE and Arista fabric architectures?

The switch is fully compatible with Arista-based fabric designs and integrates seamlessly into HPE Arista ecosystem deployments. It supports standard BGP EVPN fabric automation, allowing zero-touch provisioning and dynamic fabric scaling. Compatible with Arista CloudVision for centralized management, monitoring, and analytics across multi-switch deployments.
