Arista DCS-7050SX3-48YC8C-DC-R | 7050X3 48-Port 25G Switch, 8x 100G QSFP, 4 Tbps, DC

Q: What is the difference between the DCS-7050SX3-48YC8C-DC-R and the standard DCS-7050SX3-48YC8?
A: The 48YC8C model includes enhanced features with dual redundant power supplies and supports both AC and DC power configurations. The '-DC' suffix indicates this unit comes with DC power supplies, and the '-R' designates rear-to-front airflow cooling, which is essential for specific data center hot/cold aisle containment strategies.

Q: Can the 25GbE SFP28 ports support lower speeds like 10G and 1G?
A: Yes, all 48 SFP28 ports are flexible and support 1G, 10G, and 25G speeds, allowing you to mix and match optics based on your connectivity requirements. This flexibility makes it ideal for mixed-speed environments and gradual migration from 10G to 25G infrastructure.

Q: What makes this switch suitable for high-performance computing and financial trading applications?
A: The DCS-7050SX3-48YC8C-DC-R delivers ultra-low latency of just 800 nanoseconds with minimal jitter, combined with 4 Tbps non-blocking throughput. This consistent, predictable performance is critical for latency-sensitive applications like high-frequency trading, real-time analytics, and AI/ML workloads where every nanosecond matters.

Q: Does this switch support network virtualization technologies?
A: Yes, it fully supports VXLAN for Layer 2 overlay networks and EVPN for multi-tenant segmentation. Running Arista EOS, it provides comprehensive Layer 2 and Layer 3 features including BGP, OSPF, 128-way ECMP routing, VRF, and advanced automation capabilities through open APIs and programmable interfaces.

Q: What is the benefit of dual redundant DC power supplies?
A: Dual redundant hot-swappable DC power supplies provide 1+1 power redundancy, ensuring continuous operation even if one power supply fails. DC power is commonly used in telecom and mission-critical data center environments where -48V DC infrastructure is standard, offering enhanced reliability and eliminating the need for AC-to-DC conversion at the rack level.
