Arista 7050X3 48x25G 8x100G Data Center Switch

The Arista 7050X3 Series, model DCS-7050SX3-48YC8, is a 1RU fixed-configuration data center leaf switch delivering 48 ports of 25GbE SFP28 and 8 ports of 100GbE QSFP100 uplinks, built on a merchant silicon forwarding ASIC. The platform provides a total switching capacity of 3.2 Tbps with a forwarding rate of 2.38 Bpps, making it well suited for high-density server access and east-west traffic aggregation in modern spine-leaf architectures. The switch operates in a front-to-rear or rear-to-front airflow configuration and draws from a pair of hot-swappable, redundant power supplies to meet enterprise availability requirements.

Running Arista EOS (Extensible Operating System), the DCS-7050SX3-48YC8 exposes a fully programmable, Linux-based network operating environment with a unified state database (SysDB) that enables consistent management across CLI, SNMP, NETCONF/YANG, RESTful eAPI, and streaming telemetry via OpenConfig and gNMI. EOS supports advanced features including EVPN/VXLAN for overlay fabric construction, ECMP load balancing across up to 512 paths, and robust BGP implementations suited for large-scale leaf-spine deployments. CloudVision, Arista's network-wide management and telemetry platform, integrates natively with EOS for zero-touch provisioning, configuration change control, and continuous network-wide state monitoring.

First introduced in Q2 2018, the 7050SX3-48YC8 has established a strong track record as a high-performance 25G leaf switch in cloud provider and enterprise data center environments. Its combination of port density, low latency, deep buffer architecture relative to its form factor, and broad automation ecosystem makes it a preferred choice for organizations building or scaling hyper-converged infrastructure, GPU compute clusters, storage fabric interconnects, and high-frequency financial trading environments where deterministic forwarding latency and operational programmability are critical.

Ideal for

• 25GbE server access leaf in a spine-leaf fabric connecting hyperconverged infrastructure nodes such as Nutanix or VMware vSAN clusters
• Top-of-rack switch for high-density GPU compute environments requiring low-latency east-west interconnect between accelerated servers
• EVPN/VXLAN overlay fabric leaf node enabling multi-tenant network segmentation across enterprise data center pods
• Storage fabric access layer connecting NVMe-oF or iSCSI storage arrays requiring high-throughput, low-latency connectivity
• Financial services trading infrastructure leaf providing consistent sub-microsecond forwarding latency for co-located matching engines and market data distribution
• Enterprise data center migration platform supporting mixed 10GbE/25GbE server deployments during phased infrastructure refresh cycles
