S3K84A HPE 48p 10GBASE-T 6p QSFP+ 40G 2p QSFP28 100G TAA Managed Switch

High-Density Top-of-Rack Managed L2/L3 Ethernet Switch with 10GbE Access and 40/100GbE Uplinks using the S3K84A

The S3K84A is an HPE Comware 5710 Series managed, stackable rack-module switch designed for Top-of-Rack aggregation and leaf/access deployments where consistent 10GbE server connectivity must scale into 40/100GbE uplinks without redesigning the access layer. Its mixed-speed interface design supports phased migrations while maintaining deterministic forwarding behavior across VLAN segmentation, routing boundaries, and service policies.

Architecturally, S3K84A aligns to modern east-west traffic patterns by combining Layer 2 control (MSTP, LLDP, LACP) with Layer 3 capabilities such as ECMP, BFD, and load balancing for resilient spine-leaf fabrics and server-edge routing. Telemetry via sFlow and policy enforcement via QoS and 802.1X enable operational visibility and access control at the edge. Expansion is centered on a high-port-density 48 x 10GBASE-T access plane with high-bandwidth QSFP+/QSFP28 uplinks to upstream aggregation, optimized for consolidation where rack space and cabling simplicity matter.

Why Choose the S3K84A?

S3K84A delivers a practical density-to-performance profile for enterprise racks that require 10GBASE-T at scale while keeping uplink capacity aligned with evolving core bandwidth. With stackable operations and standards-based interoperability, S3K84A supports predictable scaling, consistent policy behavior, and streamlined rollouts across data center leaf tiers and server-edge aggregation points.

HPE engineers the Comware platform to prioritize operational stability, repeatable configuration workflows, and feature completeness for enterprise switching. S3K84A fits established 19-inch rack standards and integrates cleanly into data center change-control processes through mature L2/L3 protocol support and instrumentation suitable for modern monitoring pipelines.

Key Applications:

• Top-of-Rack 10GbE server access with 40/100GbE uplinks
• Spine-leaf leaf/access switching
• VLAN segmentation and inter-VLAN routing
• 802.1X edge access control
• QoS-based traffic engineering
