Arista DCS-7050SX3-48YC8-DC-R | 7050X3 48-Port 25G Switch, 8x 100G QSFP28, DC

Q: What is the difference between the -DC-R and standard -R model?
A: The DCS-7050SX3-48YC8-DC-R features DC power supplies instead of AC, making it suitable for telecom and co-location facilities with -48VDC infrastructure. The -R suffix indicates rear-to-front airflow for specific data center cooling strategies.

Q: Can the QSFP28 ports be broken out into lower-speed connections?
A: Yes, each 100GbE QSFP28 port supports breakout configurations into 4x25GbE or 4x10GbE logical ports, providing flexible topology design for leaf-spine architectures and phased migration from 10G to 25G networks.

Q: What virtualization and overlay protocols does this switch support?
A: The switch natively supports VXLAN for network virtualization and EVPN for modern control plane operations, enabling multi-tenant segmentation, MAC mobility, and scalable Layer 2 overlay networks in cloud environments.

Q: Is this switch suitable for high-frequency trading and HPC applications?
A: Yes, with 800-nanosecond cut-through latency, IEEE 1588 PTP precision timing support, and 32MB packet buffer, the switch delivers deterministic performance ideal for latency-sensitive HPC clusters and financial trading systems.

Q: What automation and telemetry features are included?
A: Arista EOS provides Zero Touch Provisioning for automated deployment, CloudVision integration for centralized management, LANZ for microburst detection, sFlow for traffic visibility, and native support for Python, Ansible, and Terraform.
