Obsidian introduces the Bowman Global Fabric Controller

New device provides sophisticated management services to complex multi-subnet InfiniBand fabrics spanning many organisations across the globe

Austin, TX – November 16, 2015 – Furthering Obsidian's interests in extending the scope of the InfiniBand protocol, Obsidian Longbow™ and Obsidian Crossbow™ eliminated range and single subnet limitations but there remained the issue of controlling the complex fabrics that were now possible - “Enter the Bowman Global Fabric Controller!”, said Dr. David Southwell, CVO of Obsidian Strategics.

“A new class of device capable of simultaneously managing many geo-distributed subnets was required, able to function as an enhanced subnet manager within each participating subnet while providing global services to coordinate the entire ensemble. The controller architecture must start to reflect the fabric architecture, so Bowman itself is n-way clusterable within and across subnets, providing ExaScale-class performance scaling and fault tolerance.”, continued Dr. Southwell,

“At the heart of Bowman is an entirely new, non-heuristic algorithm for forwarding table generation which is deterministic, is mathematically incapable of generating deadlock (credit cycles) and is able to route across arbitrarily complex compound topologies comprising dissimilar local topologies, such as hypercubes and fat trees. Network controllers specify target topological descriptions using Python scripts and then Bowman reconciles this target with the discovered network characteristics. Surrounding this core are many features designed for performance, high-availability and convenience at extreme scale and subnet diversity. The result is much more than a subnet manager – a new class of controller that enables complex high performance infrastructure with telecom-grade assurance and control.”

Meet the team to learn more and see the Bowman in action managing the globe-spanning InfiniCortex fabric at SC15 (Austin Convention Center, TX) - Obsidian (booth 287) from November 16th to 19th.

About Obsidian Strategics
Obsidian Strategics™ is the developer of Longbow™, Crossbow™ and Bowman™ series of InfiniBand products featuring range extension, routing, encryption and fabric controller functions. Longbow and Crossbow technologies allow an InfiniBand fabric - normally a single-subnet short-range network used within supercomputers and data centres - to be securely extended via optical fiber over global distances and many subnets. Bowman Global Fabric Controllers (BGFC) overlay management and administration services across the resulting widely distributed and complex fabric topologies, enabling unprecedented scalability, security and control. www.obsidianstrategics.com.
