The Future of High Speed Interconnect is Here! Chelsio’s Terminator 7 (T7) Unified Wire Adapters
Chelsio is delivering the future of high speed interconnect with its seventh generation technology, the Terminator 7 (T7) Unified Wire Adapters.
Chelsio’s 7th-generation ASIC technology—comprising the T7, which serves as a full-featured DPU or dedicated storage adapter variant, and the S7 Smart NIC features a PCI Express 5.0 host bus interface.
Terminator Features |
The T7 supporting 4-port 1/10/25/50G, 2-port 1/10/25/40/50/100/200G or 4x100G, and 1-port 40/100/200G (with integrated FPGA configurations), and the S7 Smart NIC supporting 1-port 400G, 4×1/10/25/50/100G, 2x200G, or multi-port 1/10/25/40/50/100/200G configurations —features a PCI Express 5.0 host bus interface optimized for storage, cloud computing, HPC, virtualization, and datacenter networking, with the T7 adding targeted support for AI workloads. This road-tested, tier-1 OEM-proven architecture delivers high performance and efficiency by utilizing on-board hardware to offload heavy communication processing from the host system—including TCP/IP, Unified RDMA (RoCEv2 & iWARP), iSCSI, NVMe-oF, NVMe/TCP, and TLS/IPsec, NVGRE and VXLAN protocols, alongside user-mode SPDK framework support for NVMe/TCP and iSCSI. By handling intensive protocol processing directly on the ASIC chip, both devices drive higher bandwidth, lower latency, and reduced power consumption while freeing up valuable host CPU cycles and maintaining backward compatibility with predecessor T4, T5, and T6 software without modification. Designed with distinct memory layouts and form factors (including HHHL, FHHL, and OCP3 options), the T7 relies on 8GB to 16GB of on-board card memory to handle compute-independent workloads across its standard storage adapters and dedicated DPU variants equipped with 8xArm cores, 8xRISC cores, and 1xDFP, whereas the S7 operates as a strictly memory-free Smart NIC that leverages host memory to deliver high-performance protocol offloads at an aggressive price point.
