Software Management

The systems include an embedded management CPU card that runs MLNX-
OS® management software.
The MLNX-OS systems management package and related documentation can be downloaded
at http://www.mellanox.com/page/mlnx_os.

InfiniBand Subnet Manager

The InfiniBand Subnet Manager (SM) is a centralized entity running in the system. The SM applies
network traffic related configurations such as QoS, routing, partitioning to the fabric devices. You
can view and configure the Subnet Manager parameters 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 system itself (system based) or
on one of the nodes which is connected to the fabric (host based).

No more than two subnet managers are recommended for any single fabric.
The InfiniBand Subnet Manager running on the system supports up to 2048 nodes. If the fabric
includes more than 2048 nodes, you may need to purchase NVIDIA's Unified Fabric Manager (UFM®)
software package.
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 system itself (system based) or
on one of the nodes which is connected to the fabric (host based).
The subnet manager (OpenSM) assigns Local IDentifiers (LIDs) to each port connected to the fabric,
and develops a routing table based on the assigned LIDs.
A typical installation using the OFED package will run the OpenSM subnet manager at system start up
after the drivers are loaded. This automatic OpenSM is resident in memory, and sweeps the fabric
approximately every 5 seconds for new adapters to add to the subnet routing tables.
Upgrading Software (on Managed Systems)
Software and firmware updates are available from the NVIDIA Support website. Check that your
current revision is the same one that is on the NVIDIA website. If not upgrade your software. Copy
the update to a known location on a remote server within the user's LAN.
Use the CLI or the GUI in order to perform software upgrades. For further information please refer
to the MLNX-OS Software User Manual section Upgrading MLNX-OS® Software.
Be sure to read and follow all of the instructions regarding the updating of the software on your
system.
Managed systems do not require Firmware updating. Firmware updating is done through the MLNX-
OS management software. The system comes standard with a management software module for
system management called NVIDIA Operating System (MLNX-OS). MLNX-OS® is installed on all
SwitchIB® based managed systems. MLNX-OS® includes a CLI, WebUI, SNMP, system management
software and IB management software (OpenSM).
