Mellanox 36 Port InfiniBand Switch

36-port Non-blocking Managed EDR 100Gb/s InfiniBand Smart Switch

Mellanox provides the world’s first smart switch, enabling in-network computing through the Co-Design Scalable Hierarchical Aggregation and Reduction Protocol (SHARP)™ technology. SB7800 has the highest fabric performance available in the market with up to 7.2Tb/s of non-blocking bandwidth with 90ns port-to-port latency

Scaling-out Data Centers With EDR 100G Infiniband

Faster servers based on PCIe 3.0, combined with high-performance storage and applications that useincreasingly complex computations, are causing data bandwidth requirements to spiral upward. As servers are deployed with next generation processors, High-Performance Computing (HPC) environments and Enterprise Data Centers (EDC) will need every last bit of bandwidth delivered with Mellanox’s next generation of Extended Data Rate (EDR) InfiniBand high-speed smart switches.

World’s First Smart Switch

Built with Mellanox’s latest Switch-IB™ 2 InfiniBand switch device, EDR uses efficient 64/66 encoding while increasing the per lane signaling rate to 25Gb/s. SB7800 provides up to thirty-six 100Gb/s full bi-directional bandwidth per port. These stand-alone switches are an ideal choice for top-of-rack leaf connectivity or for building small to extremely large sized clusters. SB7800 is the world’s first smart network switch, designed to enable in-network computing through the Co-Design Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) technology. The Co-Designarchitecture enables the usage of all active data center devices to accelerate the communications frameworks, resulting in order of magnitude applications performance improvements. SB7800 enables efficient computing with features such as static routing, adaptive routing, congestion control and enhanced VL mapping to enable modern topologies (SlimFly, Dragonfly+, 6D Torus). These ensure the maximum effective fabric bandwidth by eliminating congestion hot spots. The SB7800 switch has best-in-class design to support low power consumption. ATIS weighted power consumption is 136W for a fully-populated switch. Power is further reduced if not all ports are used or if partially utilized.

Collective Communication Acceleration

Collective communication is a term used to describe communication patterns in which all members of a group of communication endpoints participate. Collective communications are commonly used in HPC communication protocols such as MPI and SHMEM (Open-SHMEM). Collective operations have implications on overall application performance and scale. SB7800 introduces the Co-design SHARP technology, which enables the switch to manage collective communications using embedded hardware. Switch-IB 2 improves the performance of selected collective operations by processing the data as it traverses the network, eliminating the need to send data multiple times between end-points. This decreases the amount of data traversing the network and additional benefit of freeing up CPU resources for computation rather than using them to process communication. The network portion of the reduction operation on a fully-populated three-level fat-tree can be completed in less than three microseconds.

Management

SB7800, dual-core x86 CPU, comes with an onboard subnet manager, enabling simple, out-of-the-box fabric bring-up for up to 2k nodes. SB7800 switch runs the same MLNX-OS® software package as Mellanox FDR products to deliver complete chassis management, to manage the firmware, power supplies, fans and ports.
