Mellanox Certified Refurbished MCX4131A-GCAT ConnectX-4 Lx EN Network Interface Card 50GbE Single-Port QSFP28 PCIe3.0 x8 ROHS R6
With the exponential increase in usage of data and the creation of new applications, the demand for the highest throughput, lowest latency, virtualization and sophisticated data acceleration engines continues to rise. ConnectX-4 Lx EN enables data centers to leverage the world's leading interconnect adapter for increasing their operational efficiency, improving servers' utilization, maximizing applications productivity, while reducing total cost of ownership (TCO).
ConnectX-4 Lx EN provides an unmatched combination of 10, 25, 40, and 50GbE bandwidth, sub-microsecond latency and a 75 million packets per second message rate. It includes native hardware support for RDMA over Converged Ethernet, Ethernet stateless offload engines, Overlay Networks,and GPUDirect Technology.
High Max Speed Ethernet Adapter
ConnectX-4 Lx offers the best cost effective Ethernet adapter solution for 10, 25, 40 and 50Gb/s Ethernet Max Speeds, enabling seamless networking, clustering, or storage. The adapter reduces application runtime, and offers the flexibility and scalability to make infrastructure run as efficiently and productively as possible.
ConnectX-4 Lx EN SR-IOV technology provides dedi-cated adapter resources and guaranteed isolation and protection for virtual machines (VMs) within the server. I/O virtualization with ConnectX-4 Lx EN gives data center administrators better server utilization while reducing cost, power, and cable complexity, allowing more Virtual Machines and more tenants on the same hardware.
In order to better scale their networks, data center operators often create overlay networks that carry traffic from individual virtual machines over logical tunnels in encapsulated formats such as NVGRE and VXLAN. While this solves network scalability issues, it hides the TCP packet from the hardware offloading engines, placing higher loads on the host CPU. ConnectX-4 Lx EN effectively addresses this by providing advanced NVGRE, VXLAN and GENEVE hardware offloading engines that encapsulate and de-capsulate the overlay protocol headers, enabling the traditional offloads to be performed on the encapsulated traffic for these and other tunneling protocols (GENEVE, MPLS, QinQ, and so on). With ConnectX-4 Lx EN, data center operators can achieve native performance in the new network architecture.
RDMA over Converged Ethernet (RoCE)
ConnectX-4 Lx EN supports RoCE specifications delivering low-latency and high- performance over Ethernet networks. Leveraging data center bridging (DCB) capabilities as well as ConnectX-4 Lx EN advanced congestion control hardware mechanisms, RoCE provides efficient low-latency RDMA services over Layer 2 and Layer 3 networks RDMA over Converged Ethernet (RoCE)
Mellanox PeerDirect ™
PeerDirect™ communication provides high efficiency RDMA access by eliminating unnecessary internal data copies between components on the PCIe bus (for example, from GPU to CPU), and therefore significantly reduces application run time. ConnectX-4 Lx EN advanced acceleration technology enables higher cluster efficiency and scalability to tens of thousands of nodes.

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.
