How many 25GbE and 100GbE ports does the DCS-7050SX3-48YC12-F provide?

This model offers a total of forty eight 25GbE SFP interfaces and twelve 100GbE QSFP interfaces. The 25GbE ports are typically used for server or access layer connections, while the 100GbE ports are suited for uplinks to aggregation or spine switches and for high bandwidth inter switch links.

For what type of environment is the DCS-7050SX3-48YC12-F intended?

The DCS-7050SX3-48YC12-F is categorized at the datacenter product level and belongs to the Arista 7050X3 Series of Ethernet switches. Its mix of 25GbE SFP access ports and 100GbE QSFP uplinks makes it suitable for managed 10, 25 and 100GbE data center networks, including leaf and aggregation roles.

Which series does the DCS-7050SX3-48YC12-F belong to and why does that matter?

This switch is part of the Arista 7050X3 Series. Belonging to this series means it shares a common platform and design approach with other 7050X3 models, which can simplify operations, configuration standards and sparing strategies when deploying multiple switches across a data center.

Can the DCS-7050SX3-48YC12-F support mixed 10, 25 and 100GbE environments?

Yes, the product category identifies it as a managed 10, 25 and 100GbE data center switch with 48x25GbE SFP and 12x100GbE QSFP ports. This allows it to operate in environments where access links may be 10 or 25GbE while uplinks and aggregation connections run at 100GbE.

Product overview

The Arista DCS-7050SX3-48YC12-F is a data center network switch in the 7050X3 Series, designed as a 1U fixed configuration platform. It provides forty eight 25GbE SFP interfaces for server or leaf connectivity, combined with twelve 100GbE QSFP interfaces for high speed uplinks or spine connections. This combination of 25G access and 100G aggregation enables scalable designs in modern data center environments. As part of the 7050X3 Series of Ethernet switches, the DCS-7050SX3-48YC12-F is positioned for managed 10, 25 and 100GbE deployments where a compact rack unit and dense port configuration are important selection criteria. The clearly defined SFP and QSFP port groups simplify planning for structured cabling, migration from 10GbE to 25GbE, and integration into existing 100GbE aggregation tiers without changing the overall rack footprint.

Best for

Data center access
Leverage the forty eight 25GbE SFP interfaces to connect high density server racks within modern data centers that standardize on 25GbE host links.
Leaf switch
Use the 1U form factor with 48x25GbE and 12x100GbE ports as a leaf layer device, aggregating server traffic and uplinking to a 100GbE spine.
100G aggregation
Employ the twelve 100GbE QSFP interfaces to aggregate multiple lower speed access switches or to provide high bandwidth interconnects within the data center.
Rack space constrained sites
Deploy the 1U design in environments where rack space is limited but a mix of 25GbE access and 100GbE uplink capacity is required.
10, 25 and 100GbE migration
Support transitions between 10GbE, 25GbE and 100GbE by using the 25GbE SFP ports for access and the 100GbE QSFP ports for aggregation in a single platform.
