HT Connectors and Cables

HyperTransport connectivity has evolved to a full portfolio of standardized interface connectors for cable, mezzanine and slot type applications. HT connectors are engineered to perfectly complement  the high bandwidth, low latency and scalability features of HyperTransport.

Innovative In-System and System-Wide Connectivity Enablement

HT connectors and cables offer High Performance Computing (HPC), data center and advanced embedded system design architects innovative ways to maximize their systems’ and system clusters’ potential in:

• Configurability
• Compute Nodes/Functions Modularity and Scalability
• HT Networking
• System-Wide State-of-the-Art Latency, Bandwidth Performance and High Efficiency HT Protocol
• Market-Proven, Royalty-Free, Open Standard Technology

Off-the Shelf Availability

All HyperTransport interconnect components are stock components - either in volume production or fully productized – and available from leading interconnect technology vendors.
