Obsidian Plans 400G InfiniBand for the WAN

Obsidian Strategics, a privately-held company based in Canada that offers InfiniBand products featuring range extension, routing and encryption, announced plans for a new platform that will take InfiniBand to 400 Gbps rates over WAN distances.

Obsidian's Longbow technology allows an InfiniBand fabric -- normally a short-range network (up to 17m) used in supercomputers and data centers -- to be securely extended via optical fiber over global distances. Obsidian also provides its Crossbow technology that enables very high performance routing of InfiniBand traffic between many separate subnets.

The company says InfiniBand overcomes the severe performance penalties incurred at high data rates by TCP/IP and Ethernet. In the spirit of its existing Longbow and Crossbow products operating at 40 Gbps, its 100G and 400G platforms will also provide enhanced InfiniBand features such as cryptographic and routing functions.

100G InfiniBand Connects Supercomputers across Continents

Obsidian Strategics and Singapore's A*STAR Computational Resource Centre are pioneering long-distance, 100G InfiniBand as a means of interconnecting geographically distributed supercomputers. A demonstration planned for this week's SC14 conference in New Orleans aims to demonstrate the feasibility of using the technology for global supercomputer collaboration. The key is to transmit RDMA over transcontinental distances. The demo will show real...

Blueprint: InfiniBand Moves from SuperComputing to Cloud

By: Dr. David Southwell, CVO, Obsidian Strategics Some technology found inside modern supercomputers may prove to be surprisingly applicable to new data center architectures. To understand how, we must first look at the anatomy of contemporary supercomputers. Classics like the Cray vector supercomputers have long since given way to commodity silicon based designs - the vast majority of supercomputers today ar
