Scaling-Out Data Centers with Extended Data Rate (EDR) 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 proces- sors, High-Performance Computing (HPC) environ- ments and Enterprise Data Centers (EDC) will need every last bit of bandwidth delivered with Mella- nox's next generation of EDR InfiniBand high-Max Speed smart switches.
World's First Smart Switch
Built with Mellanox's latest Switch-IB TM 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 Aggrega- tion 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 improve- ments.
SB7890 enables efficient computing with features such as static routing, adaptive routing, conges- tion control and enhanced VL mapping to enable modern topologies (SlimFly, Dragonfly+, 6D Torus). These ensure the maximum effective fabric band- width by eliminating congestion hot spots.
The SB7890 switch has best-in-class design to support low power consumption. ATIS weighted power consump- tion is 122W 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 end- points participate. Collective communications are commonly used in HPC communication protocols such as MPI and SHMEM (OpenSHMEM).
Collective operations have implications on overall application performance and scale. SB7890 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.
Building Efficient Clusters
The SB7890 is the industry's most cost-effective building block for deploying high performance clus- ters and data centers. Whether looking at price-to- performance or energy-to-performance, the SB7890 offers superior performance, low power and scale reducing capital and operating expenses providing the best return-on-investment.

One-Year Limited Hardware Warranty
Mellanox Technologies (“Mellanox”) warrants that for a period of (a) 1 year (the “Warranty Term”) from the original date of shipment of the Products or (b) as otherwise provided for in the “Customer’s” (as defined herein) SLA, Products as delivered will conform in all material respects to the Product specifications in effect at the time of shipment.
Cables, Optical Modules and other Accessories are warranted for a maximum of 1 year from the date of shipment.
The warranty terms hereof are offered and made available to the original purchaser of the Products from Mellanox or, if the Products were purchased for resale, to the initial end user (such purchaser and end user herein are each a “Customer”).
During the Warranty Term, Customer may notify Mellanox in writing of any material non-conformance of the Product. Notification of any such non-conformance shall include the Product serial number(s) and a detailed description of the alleged non-conformity. Mellanox reserves the right to contact the Customer to trouble shoot or examine any allegedly non-conforming Product and perform a failure analysis to determine if the alleged non-conformity is a result of defective materials or workmanship, or does not exist, or was caused by improper use or installation or damage in transit or while in the control of the Customer (in which case, Customer shall have no warranty claims with respect to such alleged non-conforming unit).
If Mellanox determines that the non-conformity was due to defective materials or workmanship, Mellanox will issue a return authorization (RMA) for the non-conforming Product units, and the Customer will return the non-conforming unit(s) to Mellanox’s designated repair facility, freight pre-paid by the Customer, in accordance with the instructions set forth in the RMA. The Customer shall bear all risk of loss or damage to returned goods while in transit.
Mellanox shall, at its option, either (i) repair or replace non-conforming Product units, at Mellanox’s expense, and will return an equal number of conforming Product units to the Customer, or (ii) credit the Customer for any non-conforming Product units in an amount equal to the price charged on the original date of shipment multiplied by the number of affected Product units. Any such repair or replacement provided to the Customer will not extend the Warranty Term for the Products.
At the Customer’s request and at the sole discretion of Mellanox, replacement Product units may be shipped in advance of Mellanox’s receipt of alleged non-conforming Product units. If the alleged non-conforming Product units are not returned to Mellanox within 30 days of the shipment of the advanced replacement, Customer will be charged the MSRP for all such advanced-shipped Product units. A valid credit card is required to secure all advanced replacement requests. In the event the alleged non-conformance is not discovered by Mellanox after reasonable inquiry, the affected units will be returned to the Customer at the Customer’s expense and the Customer will reimburse Mellanox for the transportation charges, labor, and associated charges incurred in testing or repairing the allegedly non-conforming Product units. All replaced Product units shall become the property of Mellanox.
EXCEPT FOR THE EXPRESS WARRANTY SET FORTH HEREIN, MELLANOX AND ITS LICENSORS AND SUPPLIERS EXPRESSLY DISCLAIM ANY AND ALL OTHER WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, REGARDING THE PRODUCTS, ALL FIRMWARE AND ANY SOFTWARE, INCLUDING WITHOUT LIMITATION ANY WARRANTIES OF TITLE, NONINFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.
The foregoing sets forth Mellanox’s sole and exclusive obligation and Customer’s sole and exclusive remedy for warranty claims arising from or related to Customer’s STD and SLA. Terms not defined herein shall have the meanings assigned to them in Mellanox’s standard terms and conditions of sale, the SLA or the STD.
