Documentation
In PCIe Gen5 systems, the ConnectX-8 8240 adapter requires the use of an Auxiliary cable which plugs into a second PCIe x16 connection. The combination of the x16 host interface of the adapter plus the x16 connection of the Auxiliary cable results in a PCIe 5.0 x32 connection, needed for 800 Gb networking connectivity. Ordering information for the Auxiliary cable is listed in the following table.

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).
The following table lists the subscription licenses available from Lenovo.
