• 1 xMellanox IBM SB7890 36 100Gb/s QSFP28 EDR Infiniband Externally Managed Switch
• 2 x 460W Power Supplies 00WT061
• 4 x Fan Data Centers with ExtendedData Rate (EDR) InfiniBandFaster 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. Asservers are deployed with next generation processors, High-Performance Computing (HPC) environmentsand Enterprise Data Centers (EDC) will need every last bit of bandwidth delivered with Mellanox’s nextgeneration of Extended Data Rate (EDR) InfiniBand high-speed smart switches.
  World’s First Smart SwitchBuilt with Mellanox’s latest Switch-IB® 2 InfiniBand switch device, EDR uses efficient 64/66 encodingwhile increasing the per lane signaling rate to 25Gb/s. SB7890 provides up to thirty-six 100Gb/s fullbi-directional bandwidth per port. These stand-alone switches are an ideal choice for top-of-rack leafconnectivity or for building small to extremely large sized clusters.
  SB7890 is the world’s first smart network switch, designed to enable in-network computing through theCo-Design Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) technology. The Co-Designarchitecture enables the usage of all active data center devices to accelerate the communicationsframeworks, resulting in order of magnitude applications performance improvements.
  SB7890 enables efficient computing with features such as static routing, adaptive routing, congestioncontrol and enhanced VL mapping to enable modern topologies (SlimFly, Dragonfly+, Torus). These ensurethe maximum effective fabric bandwidth by eliminating congestion hot spots.
  The SB7890 switch has best-in-class design to support low power consumption. ATIS weighted powerconsumption is 122W for a fully-populated switch. Power is further reduced if not all ports are used or ifpartially SB7890
