Mellanox SB7890 36-port Non-blocking Externally Managed EDR 100Gb/s InfiniBand Switch – Part ID: MSB7890-ES2R

Description

SB7890 36-port Non-blocking Externally Managed EDR 100Gb/s InfiniBand SwitchBuilt 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. The SB7890 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.SB7890 is the world’s first smart network switch, designed to enable in-network computing through the Co-Design Scalable Hierarchical Aggregation Protocol (SHArP) technology. The Co-Design architecture enables the usage of all active data center devices to accelerate the communications frameworks, resulting in order of magnitude applications performance improvements.SB7890 enables efficient computing with features such as static routing, adaptive routing, and congestion control. These ensure the maximum effective fabric bandwidth by eliminating congestion hot spots.The SB7890 switch has best-in-class design to support low power consumption. ATIS weighted power consumption is 122W for a fully-populated switch. Power is further reduced if not all ports are used or if partially utilized.
