About the Arista 7388X5 Series 51.2T Data Center Switch
The Arista 7388X5 Series represents a landmark in fixed-form-factor data center switching, integrating 51.2 terabits per second of non-blocking throughput into a single high-density chassis. Built around a purpose-engineered 51.2T ASIC, the platform consolidates 64 native 800GbE QSFP-DD800 ports into a compact footprint designed for the most bandwidth-intensive hyperscale and AI/ML fabric deployments. The architecture supports breakout configurations down to 400G, 200G, 100G, and 40G, enabling seamless integration with existing installed-base infrastructure while providing a clear upgrade path as network demands escalate. Power-per-bit efficiency is a primary design objective, making the 7388X5 one of the most operationally economical spine-layer switches available for large-scale leaf-spine fabrics launched in the first quarter of 2026.
Ideal for
- Hyperscale AI/ML GPU cluster spine interconnect requiring maximum 800GbE density for distributed training and inference workloads
- Cloud data center leaf-spine fabric upgrade to 800G spine tier, enabling non-blocking connectivity across thousands of 400G-attached compute nodes
- Financial services ultra-low-latency trading infrastructure demanding deterministic forwarding and high-resolution hardware timestamping at spine layer
- Multi-tenant colocation provider core switching where EVPN-VXLAN overlays and high-density port counts reduce total rack space and power draw per tenant
- High-performance computing (HPC) research networks requiring terabit-class backbone bandwidth for large dataset transfers and simulation workloads
- Service provider peering and internet exchange aggregation points consolidating multiple 400G or 800G upstream and downstream transit connections into a single fixed-form device
