- Switch-IB 2 Based EDR InfiniBand 1U Switch 36 QSFP28 Ports 100Gb/s 2 Power Supplies AC Unmanaged Standard Depth P2C (Back-to-Front) Airflow RoHS6
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. 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 and Reduction 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, congestion
control and enhanced VL mapping to enable modern topologies (SlimFly, Dragonfly+, Torus). 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
