The AurCore AES6103B is a 1U data center switch featuring 48 x 25GE SFP28 and 6 x 100GE QSFP28 ports, delivering 4 Tbps switching capacity and a forwarding rate of 2800 Mpps. Each QSFP28 port supports native 100GE/40GE operation, and can be channelized via breakout cables into 4 x 25GE or 4 x 10GE for maximum deployment flexibility. Powered by the Marvell Falcon chipset, it is optimized for deployment as a Top-of-Rack switch supporting 25GE server connectivity with 100GE uplinks in high-performance data center environments. The AES6103B is built for carrier-grade reliability and operational continuity, featuring hot-swappable, load-sharing redundant AC or DC PSUs, 4+1 redundant hot-swappable fan modules, and back-to-front airflow support for hot/cold aisle configurations. A dual U-Boot design ensures system-level redundancy for mission-critical deployments. Running on AURC-NOS, it supports advanced data center features including VXLAN, EVPN, MLAG, and RoCE v2, along with comprehensive routing protocols such as BGP, OSPF, IS-IS, and MPLS. Telemetry-based and NETCONF-based network monitoring enables smart O&M for more efficient and accurate network management.
