High Performance Computing Environments
With its NVIDIA In-Network Computing and In-Network Memory capabilities,ConnectX-6 offloads computation even further to the network, saving CPU cyclesand increasing network efficiency. ConnectX-6 utilizes remote direct memory access(RDMA) technology as defined in the InfiniBand Trade Association (IBTA) specification,delivering low latency, and high performance. ConnectX-6 enhances RDMA networkcapabilities even further by delivering end-to-end packet-level flow control.
Machine Learning and Big Data Environments
Data analytics has become an essential function within many enterprise datacenters, clouds, and hyperscale platforms. Machine learning (ML) relies onespecially high throughput and low latency to train deep neural networks andimprove recognition and classification accuracy. With its 200Gb/s throughput,ConnectX-6 is an excellent solution to provide ML applications with the levels ofperformance and scalability that they require.
Security Including Block-Level Encryption
ConnectX-6 block-level encryption offers a critical innovation to network security.As data in transit is stored or retrieved, it undergoes encryption and decryption.ConnectX-6 hardware offloads the IEEE AES-XTS encryption/decryption from theCPU, saving latency and CPU utilization. It also guarantees protection for userssharing the same resources through the use of dedicated encryption keys.By performing block storage encryption in the adapter, ConnectX-6 eliminates theneed for self-encrypted disks. This gives customers the freedom to choose theirpreferred storage device, including byte addressable and NVDIMM devices thattraditionally do not provide encryption. Moreover, ConnectX-6 can offer FederalInformation Processing Standards (FIPS) compliance.
Bring NVMe-oF to Storage Environments
NVMe storage devices are gaining momentum, offering very fast access to storage media.The evolving NVMe over Fabrics (NVMe-oF) protocol leverages RDMA connectivity toremotely access NVMe storage devices efficiently, while keeping the end-to-end NVMemodel at lowest latency. With its NVMe-oF target and initiator offloads, ConnectX-6brings further optimization to NVMe-oF, enhancing CPU utilization and scalability.
Portfolio of Smart Adapters
ConnectX-6 is available in two form factors: low-profile stand-up PCIe and OpenCompute Project (OCP) Spec 3.0 cards with QSFP connectors. Single-port, HDR, stand-upPCIe adapters are available based on either ConnectX-6 or ConnectX-6 DE (ConnectX-6Dx enhanced for HPC applications).In addition, specific PCIe stand-up cards are available with a cold plate for insertion intoliquid-cooled Intel Server System D50TNP platforms.
