InfiniBand Subnet Manager
The InfiniBand Subnet Manager (SM) is a centralized entity running in the switch. It discovers
and configures all the InfiniBand fabric devices to enable traffic flow between those devices. The
SM applies network traffic related configurations such as QoS, routing, partitioning to the fabric
devices.
You can view and configure the Subnet Parameters (SM) via the CLI/WebUI. Each subnet needs
one subnet manager to discover, activate and manage the subnet.
Each network requires a Subnet Manager to be running in either the switch itself (switch based)
or on one of the nodes which is connected to the fabric (host based).
8.2
Fabric Inspector (Diagnostics)
Fabric Inspector is a plug & play software for fee within MLNX-OS® displaying and filtering all
identified systems and nodes within the fabric.
Fabric Inspector includes a complete set of tools for fabric wide diagnostics to check node-node
and node-switch connectivity and to verify routes within the fabric.
Advanced filtering allows creating filtering rules on a system wide basis, between nodes or port
connections based on traffic patterns and user assigned system names (GUIDs).
