Product Description

MCX4121A-XCAT ConnectX-4 Lx EN Adapter Card 25GbE Dual-Port SFP28 PCIe 3.0 x8 ROHS R6

ConnectX-4 MCX4121A-XCAT  Lx EN network interface card with 25Gb/s Ethernet connectivity addresses virtualized infrastructure challenges,delivering best-in-class and highest performance to various demanding markets and applications.

Providing true hardware-based I/O isolation with unmatched scalability and efficiency, achieving the most cost

-effective and flexible solution for Web 2.0, Cloud,data analytics, database, and storage platforms.

MCX4121A-XCAT 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 server utilization,maximizing applications productivity, while reducing total

cost of ownership (TCO).

ConnectX-4 MCX4121A-XCAT Lx EN adapter cards provide a combination of 1 and 10 GbE bandwidth, sub-microsecond latency

and a 75 million packets per second message rate. They include native hardware support for RDMA over

Converged Ethernet (RoCE), Ethernet stateless offload engines, Overlay Networks, GPUDirect technology

and Multi-Host technology.


MCX4121A-XCAT Benefits

* High performance boards for applications requiring high bandwidth, low latency and high message rate
* Industry leading throughput and latency for Web 2.0, Cloud and Big Data applications
* Smart interconnect for x86, Power, ARM, and GPU-based compute and storage platforms
* Cutting-edge performance in virtualized overlay networks
* Efficient I/O consolidation, lowering data center costs and complexity
* Virtualization acceleration
* Power efficiency

* Virtualization
* Low latency RDMA over Converged Ethernet (RoCE)
* Multi-Host technology connects up to 4 independent hostsc
* CPU offloading of transport operations
* Application offloading
* PeerDirect communication acceleration
* Hardware offloads for NVGRE, VXLAN and GENEVE encapsulated traffic
* End-to-end QoS and congestion control
* Hardware-based I/O virtualization
* RoHS compliant
* ODCC compatible
* Various form factors available


MCX4121A-XCAT 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.
All Mellanox adapter cards  MCX4121A-XCAT are supported by Windows, Linux distributions, VMware, FreeBSD, and Citrix XENServer. ConnectX-4 Lx EN supports various management interfaces and has a rich set of tools for configuration and management across operating systems.
Additionally, ConnectX-4 MCX4121A-XCAT Lx EN provides the option for a secure firmware update check using digital signatures to prevent remote attackers from uploading malicious firmware images; this ensures that only officially authentic images produced by Mellanox can be installed, regardless whether the source of the installation is the host, the network, or a BMC.
