Cray Research and Interphase Corp. Achieve Industry-Leading ATM Performance

Strategic Insights -

Cray Research and Interphase Corp. have announced industry-leading ATM performance of nearly 400 million bits per second on a Cray SuperServer 6400 using Interphase's 4615 SBus ATM adapters. This achievement is significant as it allows data, voice, and video transmissions over a single physical connection, with a sustained throughput of 382 Mbps using the full TCP/IP protocol. The system has four Interphase 4615 OC3 Adapters connected to the CS6400 system's I/O bus, demonstrating the scalability of the Interphase adapter and the CS6400 I/O software. This combination enables customers to take advantage of the most powerful computers on the market and the fastest, high-capacity ATM adapters.

Key Takeaways:

  • Cray Research and Interphase Corp. have achieved industry-leading ATM performance of nearly 400 million bits per second on a Cray SuperServer 6400 using Interphase's 4615 SBus ATM adapters.
  • The system sustained 382 Mbps (or 48 MBytes per second) throughput using the full TCP/IP protocol.
  • The four Interphase 4615 OC3 Adapters connected to the CS6400 system's I/O bus demonstrate the scalability of the Interphase adapter and the CS6400 I/O software.
  • The combination of the Cray SuperServer 6400 and Interphase ATM adapters enables customers to take advantage of the most powerful computers on the market and the fastest, high-capacity ATM adapters.
  • The system is expected to support up to 62 ATM connections, with an aggregate I/O bandwidth of more than six gigabits per second.
  • The Cray SuperServer 6400 provides leading performance in I/O transaction volume ability and large I/O transfers, with a price starting at under $400,000 (list price U.S.).

Statistics:

  • 400 million bits per second (Mbps) – industry-leading ATM performance achieved by Cray Research and Interphase Corp.
  • 382 Mbps – sustained throughput using the full TCP/IP protocol.
  • 48 MBytes per second – equivalent throughput to 382 Mbps.
  • 62 ATM connections – maximum number of connections expected to be supported by the system.
  • 6 gigabits per second – aggregate I/O bandwidth of the system.
  • $400,000 – starting price (list price U.S.) for the Cray SuperServer 6400 system.
