Features
The adapters have the following features:
- Accelerated Networking and Security
ConnectX-7 provides a broad set of software-defined, hardware-accelerated networking, storage, and security capabilities which enable organizations to modernize and secure their IT infrastructures. Moreover, ConnectX-7 empowers agile and high-performance solutions from edge to core data centers to clouds, all while enhancing network security and reducing the total cost of ownership.
- Accelerate Data-Driven Scientific Computing
ConnectX-7 provides ultra-low latency, extreme throughput, and innovative NVIDIA In-Network Computing engines to deliver the acceleration, scalability, and feature- rich technology needed for today’s modern scientific computing workloads.
- Accelerate Software- Defined Networking
NVIDIA ASAP2 technology accelerates software-defined networking, delivering line-rate performance with no CPU penalty.
- Enhance Storage Performance
ConnectX-7 enables high- performance and efficient data storage by leveraging RDMA/RoCE, GPUDirect Storage, and hardware-based NVMe-oF offload engines.
- SharedIO (4XC7A86670 only)
SharedIO (Shared I/O or Multi-Host) is an implementation of Sockets Direct that is offered in Lenovo direct water-cooled (DWC) servers such as the SD650 V3, where there are two server nodes per DWC tray. In this implementation, the ConnectX-7 adapter is installed in a PCIe slot in one node and the adapter is connected via a cable to a PCIe connector on the second node. The result is that the two nodes share the network connection of the adapter with significant savings both in the cost of the adapters but also the cost of switch ports.

NVIDIA Unified Fabric Manager
NVIDIA Unified Fabric Manager (UFM) is InfiniBand networking management software that combines enhanced, real-time network telemetry with fabric visibility and control to support scale-out InfiniBand data centers.
The two offerings available from Lenovo are as follows:
- UFM Telemetry for Real-Time Monitoring
The UFM Telemetry platform provides network validation tools to monitor network performance and conditions, capturing and streaming rich real-time network telemetry information, application workload usage, and system configuration to an on-premises or cloud-based database for further analysis.
- UFM Enterprise for Fabric Visibility and Control
The UFM Enterprise platform combines the benefits of UFM Telemetry with enhanced network monitoring and management. It performs automated network discovery and provisioning, traffic monitoring, and congestion discovery. It also enables job schedule provisioning and integrates with industry-leading job schedulers and cloud and cluster managers, including Slurm and Platform Load Sharing Facility (LSF).
