SCALING-OUT DATA CENTERS WITH EDR 100G INFINIBAND
Faster servers based on PCIe 3.0, combined with high-performance storage and applications that use
increasingly 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.
SUSTAINED NETWORK PERFORMANCE
Built with Mellanox’s latest Switch-IB™ InfiniBand switch device, EDR uses efficient 64/66 encoding
while increasing the per lane signaling rate to 25Gb/s. SB7790 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.
SB7790 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
features ensure the maximum effective fabric bandwidth by eliminating congestion hot spots.
WORLD-CLASS DESIGN
SB7790 is an elegant top of the rack design, created for performance, serviceability, energy savings
and high-availability. SB7790 comes with two highly efficient, 80 gold+ and energy star certified, power
supplies. The SB7790 switch has best in class design to support low power consumption. ATIS weighted
power consumption is 122W for a fully populated switch with more power reduction if not all ports are
used or fully utilized. SB7790 has redundant power supplies (1+1) and fan draws (N+1) both with air
shutters for achieving maximal thermal protection.
BUILDING EFFICIENT CLUSTERS
SB7790 is the industry’s most cost-effective building block for deploying high performance clusters and
data centers. Whether looking at price-to-performance or energy-to-performance, the SB7790 offers
superior performance, low pow
