13.2.1 Overview of Subnet Manager
The subnet manager (SM) manages all operational characteristics of the InfiniBand
network, such as the following:
•
Discovering the network topology
•
Assigning a local identifier (LID) to all ports connected to the network
•
Calculating and programming switch forwarding tables
•
Programming Partition Key (
PKEY
) tables at HCAs and switches
•
Programming QoS tables (Service Level to Virtual Lane mapping tables, and
Virtual Lane arbitration tables)
•
Monitoring changes in the fabric
The InfiniBand network typically has more than one SM, but only one SM is active at a
time. The active SM is Master SM, others are Standby SMs. If the master SM shuts
down or fails, a standby SM will automatically become the master SM.
Note:
In the Exalogic machine, the InfiniBand switches (both leaf and spine) are
automatically configured to separate the IP over InfiniBand (IPoIB) traffic and
the Ethernet over InfiniBand (EoIB) traffic.
13.2.2 Subnet Manager Operation in Different Rack Configurations

should run in different rack configurations.
