CALIENT To Show InfiniBand-Based Hybrid Packet-Optical Circuit Switch Networks for High-Performance Computing at SC13

Company Partners with Molex for InfiniBand Networks; CALIENT VP of Marketing to Present on Hybrid Packet-Optical Circuit Switching for HPC Data Centers 

DENVER, Nov. 19, 2013 — CALIENT Technologies, Inc., the global leader for optical circuit switching technology, will be at the Supercomputing Conference 2013 (SC13) in Denver, November 17-22, 2013 (booth #4219), where it will highlight the use of its S320 high-density photonic switch in high-performance computing (HPC) applications.

CALIENT has teamed with Molex Inc. to demonstrate an InfiniBand hybrid packet-optical circuit switched network architecture at the CALIENT booth #4219. The solution combines Molex QSFP+ LR silicon photonics-based active optical cables with CALIENT’s low latency S320 3D MEMS optical circuit switch. The demonstration will highlight the potential for very low latency port mapping within an InfiniBand network.

Additionally, Daniel Tardent, CALIENT vice president of marketing, will deliver a presentation on hybrid packet optical circuit switching. On Thursday, November 21 at 11:00 a.m., Tardent will present “Hybrid Packet-Optical Circuit Switching Helps HPC Data Centers Handle Large Data Flows” in room 503/504.

In this presentation, chaired by William E. Allcock of Argonne National Laboratory, Tardent will introduce the audience to the hybrid packet-optical network and the role of photonic optical circuit switches in the HPC data center.

CALIENT’s S320 is used to create a network fabric with total throughput of more than 32 terabits per second.  The switch allows any-to-any network connections with almost no latency and can be reconfigured on demand through software-defined network (SDN) control.  Each switch port is transparent to bit rate and can support data speeds to 100 Gbps and beyond.  The S320 is used in cloud data centers, collocation and multi-tenant facilities, other emerging datacenter applications, and is a powerful component for next-generation SDN data centers.

“We’re excited to debut the S320 and the Molex solution to this audience as we believe the combined solution offers real benefits in InfiniBand-based data center and HPC networks,” Tardent said. “I’m also looking forward to sharing details on the hybrid packet-optical circuit switch network architecture because I believe it can provide significant bandwidth and performance for the high-value applications that run in these HPC data centers.”
