GIGABYTE’s CLN4C42 dual-port LAN add on card features a Mellanox ConnectX-4 Lx EN network controller, providing 25Gb/s Ethernet connectivity to address virtualized infrastructure challenges for today’s demanding markets and applications. Providing true hardware-based I/O isolation with unmatched scalability and efficiency, the ConnectX-4 Lx controller provides a cost-effective and flexible Ethernet adapter solution for hyperscale, cloud infrastructures, enterprise datacenters and more, delivering best- in-class performance with smart offloading.
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. The ConnectX-4 Lx EN controller on GIGABYTE’s CLN4C42 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 (MPLS, QinQ, and so on). With ConnectX-4 Lx EN, data center operators can achieve native performance in the new network architecture.
GIGABYTE’s CLN4C42 features native hardware support for RDMA over Converged Ethernet (RoCE), a network protocol that allows remote direct memory access (RDMA) over an Ethernet network. 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.
SR-IOV technology featured on GIGABYTE’s CLN4C42 provides dedicated adapter resources and guaranteed isolation and protection for virtual machines (VMs) within the server. I/O virtualization 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.
Mellanox PeerDirect™ communication acceleration 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.
ConnectX-4 Lx EN delivers advanced Erasure Coding offloading capability, enabling distributed Redundant Array of Inexpensive Disks (RAID), 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 Lx EN’s Reed-Solomon capability introduces redundant block calculations, which, together with RDMA, achieves high performance and reliable storage access.
GIGABYTE’s CLN4C24 is PXE (Preboot eXecution Environment) capable, allowing the host client to boot a software assembly retrieved from a network via industry-standard network protocols such as DHCP and TFTP.
