The Arista 7050SX3-48YC12 is built for data centre leaf deployments that need dense server connectivity and a stronger upstream path. Its 48 SFP28 access ports and 12 QSFP28 uplinks help reduce rack-level congestion and keep performance consistent as east-west traffic grows.
As rack density rises and more east-west traffic is pushed through shared fabric paths, infrastructure teams need leaf switching that can keep server access dense without letting uplink demand become the limiting factor.
The Arista 7050SX3-48YC12 is a 1RU leaf switch for data centre deployments that need high-density 25GbE server connectivity and stronger upstream capacity. Its 48×SFP28 access ports and 12×QSFP28 uplinks suit racks carrying virtualisation, storage access, build traffic, or other mixed production workloads.
This port profile gives operations teams a practical way to keep many hosts close to shared services while preserving more fabric headroom on the way northbound. That matters when a single rack must carry regular application traffic, backup activity, or bursty compute jobs without forcing the leaf to absorb all the pressure.
By matching dense 25GbE access with a stronger uplink profile, the platform helps reduce rack-level congestion and supports more consistent throughput as workloads scale. It is a straightforward fit for environments where predictable performance and manageable oversubscription are both part of day-to-day operations.
Our team can help you assess whether the Arista 7050SX3-48YC12 fits your rack design, uplink strategy, and production workload mix.
The Arista 7050SX3-48YC12 is a high-performance data center switch for leaf-spine and aggregation environments, designed to provide predictable Ethernet connectivity and scalable throughput for demanding network fabrics.
High-Density Ethernet Access
The platform provides 48×SFP28 ports and 12×QSFP28 uplinks for dense top-of-rack and fabric connectivity.
100G Fabric Scaling
Its architecture supports maximum port speeds up to 100G for higher-bandwidth interconnects across the network fabric.
Nonblocking Switching Capacity
The switch delivers 4800 Gbps of switching capacity to support high-throughput forwarding across active ports.
Mixed-Speed Integration
The port mix allows access and uplink connectivity to be aligned within a single switching platform.
Fabric-Oriented Deployment
The switch is positioned for data center deployment where predictable switch behavior and structured fabric design are required.
Aggregation Flexibility
Its port architecture supports both server-facing access and higher-speed uplink roles within the same system.
Capacity Planning Headroom
The platform’s 100G uplink capability and 4800 Gbps switching capacity help align growth planning with fabric demand.
If you are designing a leaf-spine fabric or expanding high-density switching capacity, our Arista specialists can help align the 7050SX3-48YC12 to your network requirements.

The Arista 7050SX3-48YC12 is a 25GbE top-of-rack switch for dense server and storage-access racks that push heavy traffic northbound. It fits teams that need stronger uplink headroom without adding another aggregation layer.
In dense virtualisation racks, backup windows and replication streams can overwhelm a standard leaf. This model gives infrastructure teams more uplink capacity for VM mobility, database access and storage traffic, helping keep rack-level queues under control.
Media workflows create bursts from edit stations, render nodes and ingest servers all reaching shared storage at once. The 7050SX3-48YC12 helps preserve interactive editing performance when large files and project assets move between racks.
Finance teams running pricing, reporting and risk jobs need many 25GbE hosts to feed time-sensitive data without fabric contention. The added uplink profile suits racks where replay jobs and batch runs compete for the same path.
Software development teams often see container pulls, artifact writes and test logs leave the rack in bursts. This switch gives build farms and Kubernetes nodes more headroom during parallel release cycles, reducing delays at shared services.
Telecoms environments mix packet-processing VMs, service-chain traffic and monitoring probes in the same rack. The 7050SX3-48YC12 supports that combination by keeping northbound handoff capacity available while validation traffic stays active.
Our team can help design and deploy Arista 7050SX3-48YC12 switching for virtualisation, media, finance, software build and telecoms racks, with guidance on uplink planning, rack layout and deployment fit.
