Description: Mellanox ConnectX-4 EN MCX413A-GCAT - Network adapter - PCIe 3.0 x8 - 50 Gigabit QSFP x 1
Mfr Part #: MCX413A-GCAT
ConnectX-4 EN network controller with great Ethernet connectivity provides high performance and excellent flexible solution for high performance, Web 2.0, cloud, data analytics, database, and storage platforms.
With the exponential growth of data being shared and stored by applications and social networks, the need for high-speed and high performance compute and storage data centers is skyrocketing. ConnectX-4 EN provides exceptional high performance for the incredibly demanding data centers, public and private clouds, Web2.0 and BigData applications, and storage systems, enabling modern corporations to meet the demands of the data explosion.
ConnectX-4 EN provides an unmatched combination of a high bandwidth in a single port, incredibly low latency, and specific hardware offloads, addressing both modern and the next-generation's compute and storage data center demands.
- Erasure Coding offload
- T10-DIF signature handover
- CPU offloading of transport operations
- Application offloading
- Mellanox PeerDirect communication acceleration
- Hardware offloads for NVGRE, VXLAN and GENEVE encapsulated traffic
- End-to-end QoS and congestion control
- Hardware-based I/O virtualization
- Excellent cluster, network, and storage performance
- Efficient I/O consolidation, lowering data center costs and complexity
- Power efficiency
- I/O virtualization
ConnectX-4 EN SR-IOV technology provides dedicated adapter resources and guaranteed isolation and protection for Virtual Machines (VMs) within the server. I/O virtualization with ConnectX-4 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.
- Overlay networks
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. 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 effectively addresses this by providing advanced NVGRE 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. With ConnectX-4, data center operators can achieve native performance in the advanced network architecture.
- RDMA over Converged Ethernet (RoCE)
ConnectX-4 EN supports RoCE specifications delivering low-latency and high-performance over Ethernet networks. Leveraging Data Center Bridging (DCB) capabilities as well as ConnectX-4 EN advanced congestion control hardware mechanisms, RoCE provides efficient low-latency RDMA services over Layer 2 and Layer 3 networks.
- Mellanox PeerDirect
PeerDirect communication provides high-efficiency RDMA access by eliminating unnecessary internal data copies between components on the PCIe bus, and therefore significantly reduces application run time. ConnectX-4 advanced acceleration technology enables higher cluster efficiency and scalability to tens of thousands of nodes.
- Storage acceleration
Storage applications will see improved performance with the higher bandwidth ConnectX-4 EN delivers. Moreover, standard block and file access protocols can leverage RoCE for high-performance storage access. A consolidated compute and storage network achieves significant cost-performance advantages over multi-fabric networks.
- Erasure Coding offload
ConnectX-4 EN delivers advanced Erasure Coding offloading capability, enabling distributed Redundant Array (RAID) of Inexpensive Disks, a data storage technology that combines multiple disk drive components into a logical unit for the purposes of data redundancy and performance improvement. ConnectX-4 EN's Reed-Solomon capability introduces redundant block calculations, which, together with RDMA, achieves high performance and reliable storage access.
- Signature handover
ConnectX-4 EN supports hardware checking of T10 Data Integrity Field/Protection Information (T10-DIF/PI), reducing the CPU overhead and accelerating delivery of data to the application. Signature handover is handled by the adapter on ingress and/or egress packets, reducing the load on the CPU at the Initiator and/or Target machines.
- Host management
Mellanox host management and control capabilities include NC-SI over MCTP over SMBus, and MCTP over PCIe - Baseboard Management Controller (BMC) interface, as well as PLDM for Monitor and Control DSP0248 and PLDM for Firmware Update DSP0267.
