Description: Mellanox ConnectX-4 EN MCX415A-GCAT - Network adapter - PCIe 3.0 x16 - 50 Gigabit QSFP x 1
Mfr Part #: MCX415A-GCAT
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 demanding data centers, public and private clouds, and storage systems, enabling today's corporations to meet the demands of the data explosion. ConnectX-4 EN provides an amazing combination of high bandwidth in a single port, low latency, and specific hardware offloads, addressing compute and storage data center demands.
- High-performing silicon for applications requiring high bandwidth, low latency and high message rate
- Great performance in virtualized overlay networks
- Efficient I/O consolidation, lowering data center costs and complexity
- End-to-end QoS and congestion control
- Hardware-based I/O virtualization
- Erasure Coding offload
- CPU offloading of transport operations
- Application offloading
- Power efficiency
- I/O virtualization
ConnectX-4 EN SR-IOV technology provides dedicated adapter resources and 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 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 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.
- 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 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 provides redundant block calculations, which, together with RDMA, achieves high performance and reliable storage access.
