H3C S6520X-HI Series Data Center Switch

The H3C S6520X-30QC-HI is a high-performance data center aggregation switch built on H3C's Comware V7 operating system, delivering a non-blocking switching architecture optimized for spine-leaf fabric deployments. The platform provides a combination of high-density 10GbE, 25GbE, and 40GbE connectivity in a compact 1U form factor, making it well suited for east-west traffic patterns characteristic of modern hyperconverged and virtualized data center environments. Hardware-based VXLAN bridging and routing capabilities allow the switch to serve as both an overlay gateway and an underlay forwarding node within large-scale SDN fabrics.

The S6520X-30QC-HI supports advanced Layer 2 and Layer 3 feature sets including EVPN control-plane integration, BGP EVPN-based multi-tenancy, and IRF2 (Intelligent Resilient Framework) stacking for simplified management and redundancy. The switch includes support for ECMP-based load balancing across multiple uplinks and integrates hardware telemetry capabilities for real-time traffic visibility. High-availability features such as Graceful Restart, BFD, and rapid failover mechanisms minimize disruption during topology changes or planned maintenance windows.

Designed for enterprise IT teams managing demanding compute and storage workloads, the S6520X-30QC-HI integrates with H3C's IMC (Intelligent Management Center) and is compatible with OpenFlow-based SDN controllers. Its deep buffer architecture and hardware-enforced QoS policies help maintain consistent latency for latency-sensitive applications such as all-flash storage arrays, real-time analytics clusters, and high-frequency transaction processing environments.

Ideal for

• Spine or leaf node in a scalable CLOS spine-leaf data center fabric supporting large virtualized server deployments
• VXLAN gateway for multi-tenant network segmentation across hyperconverged infrastructure clusters
• High-density 10/25GbE server access aggregation layer supporting NVMe-oF and iSCSI all-flash storage arrays
• Top-of-rack or end-of-row aggregation switch interconnecting multiple server access switches within a data center pod
• Underlay switching fabric for SD-WAN or SD-DC deployments requiring EVPN/BGP-based automated provisioning
• Campus core or data center interconnect node within enterprises consolidating multiple distributed server rooms onto a unified fabric
