The Arista DCS-7050SX3-48YC8-F is purpose-built to deliver ultra-low latency and high throughput in a compact 1RU form factor. It belongs to Arista’s 7050X3 series, optimized for high-performance leaf deployments in cloud-scale data centers, hyperscale infrastructure, and high-frequency trading environments.
With a dense port layout and wire-speed capabilities, the DCS-7050SX3-48YC8-F is engineered to support rapid east-west traffic, workload mobility, and bandwidth-intensive applications with minimal jitter.
Powered by a third-generation Broadcom Trident chipset, the Arista DCS-7050SX3-48YC8-F delivers 4.0 Tbps non-blocking throughput and forwards up to 1 billion packets per second. This architecture ensures consistent high I/O performance under full load, supporting demanding applications with low latency and minimal packet loss.
Latency is a critical factor in high-performance environments like financial trading, real-time analytics, and scientific simulations. The DCS-7050SX3-48YC8-F provides consistent sub-microsecond latency, typically around 800 nanoseconds, with low jitter. This ensures predictable and reliable performance for latency-sensitive applications where every nanosecond counts.
The Arista DCS-7050SX3-48YC8-F provides 48 SFP28 ports compatible with 10GBASE and 25GBASE optics and direct-attach cables (DACs), paired with 8 QSFP28 ports supporting native 40GBASE or 100GBASE speeds. QSFP28 interfaces also support breakout configurations into 4x25G or 4x10G links, enabling granular bandwidth allocation.
This flexible, mixed-speed architecture facilitates scalable leaf and aggregation deployments, allowing operators to implement phased migration strategies from 10G to 25G and 100G networks without disruption.
The DCS-7050SX3-48YC8-F supports a broad ecosystem of standards-based optics and cables:
This ensures smooth integration into existing infrastructure and supports diverse deployment scenarios.
Designed as a high-performance leaf switch in spine-leaf architectures, the Arista DCS-7050SX3-48YC8-F enables scalable Layer 2 and Layer 3 deployments with robust support for overlay networks and advanced routing. VXLAN provides virtualized Layer 2 overlays, facilitating large-scale network virtualization. EVPN delivers scalable, multi-tenant segmentation with efficient control-plane learning and MAC mobility. The switch also supports up to 128-way Equal-Cost Multi-Path (ECMP) routing, optimizing path selection and load balancing across the fabric for maximum throughput and resilience.
Key features include:
Operational visibility is a core design element of the DCS-7050SX3-48YC8-F. It includes support for Arista’s advanced telemetry stack:
These tools provide the data needed to troubleshoot issues before they affect applications.
Running on Arista EOS®, the DCS-7050SX3-48YC8-F benefits from a fully programmable and modular operating system. EOS enables automation at every layer of the stack:
EOS’s consistent state management architecture ensures network changes are predictable and recoverable.
The “-F” in the model denotes front-to-rear airflow, making it ideal for hot/cold aisle containment in traditional data center layouts. The Arista DCS-7050SX3-48YC8-F includes:
These features help reduce operational costs while maximizing rack density.
Designed for environmental responsibility, the DCS-7050SX3-48YC8-F complies with RoHS and WEEE regulations, and aligns with ENERGY STAR® power efficiency goals. Its hardware design minimizes toxic materials and supports recycling initiatives.
Security is integrated in both hardware and software:
Combined with VXLAN and EVPN, these features enforce scalable tenant isolation and segmentation.
The Arista DCS-7050SX3-48YC8-F is versatile and well-suited to a variety of environments:
Arista’s hardware lifecycle strategy includes long-term support for platforms like the DCS-7050SX3-48YC8-F. With MTBF ratings in the millions of hours and robust firmware release schedules, this switch is a long-term investment in infrastructure stability.
Future enhancements to EOS and CloudVision ensure the platform stays up to date with evolving network paradigms like intent-based networking and AI-driven operations.
Compared to previous-generation Arista switches (e.g., 7050SX2), the SX3 offers higher port density, double the throughput, and enhanced telemetry support. When placed side-by-side with alternatives like the Cisco Nexus 9300 series or Juniper QFX5120:
These factors give the Arista DCS-7050SX3-48YC8-F a clear edge in modern data center deployments.
If you’re evaluating the Arista DCS-7050SX3-48YC8-F, the following models offer comparable capabilities across 25G, 100G, and mixed-density deployments. These switches provide alternative port layouts, airflow options, and throughput levels depending on your specific data center architecture.
Together, these models form a practical comparison set for engineers designing 25G/100G leaf layers, spine uplinks, or mixed-workload data center fabrics.
