The HPE S4A51A is a member of the Aruba CX 8325P Switch Series, a high-performance Layer 3 switch designed for demanding campus core, aggregation, and data center Top-of-Rack (ToR) or End-of-Row (EoR) deployments. It addresses the need for a scalable, high-density 40/100 GbE solution capable of handling the increasing traffic demands driven by mobile, cloud, and IoT applications. This switch provides a robust foundation for modern networks requiring high availability and low latency. Built on the modern, cloud-native ArubaOS-CX operating system, the switch features a microservices architecture that delivers high availability and simplifies network operations. Its fully programmable nature, combined with the Aruba Network Analytics Engine, provides advanced automation, deep visibility, and rapid troubleshooting capabilities. This allows network administrators to move from reactive problem-solving to proactive, intelligent network management. With a compact 1U form factor, the S4A51A is engineered for efficient deployment in constrained spaces. This model is a bundle that includes two AC power supplies and six fan trays configured for front-to-back airflow, ensuring optimal cooling in standard data center hot-aisle/cold-aisle layouts. Its comprehensive feature set, including BGP, OSPF, VRF, and VXLAN, makes it a versatile and powerful platform for building resilient and scalable network infrastructures.
