Switch-Mode Supported Topology
In switch mode, the topology is the overall deployment.
The topology consists of sites, or
datacenters, and each datacenter contains the
virtualization switches that house the IB LR module(s).
The diagram shows two distinct datacenters and how the hosts, Oracle
InfiniBand IS2-46s (leaf switches), and virtualization
switches should be connected. Notice that the IB LR links are the only
connections that cross the datacenter boundary. For the connection procedure,
see Connect the Datacenters.

Host connections
4x IB connections (magenta ports on the leaf
switch).

Inter-switch connections, leaf and virtualization
switches
12x IB connections (black ports on the leaf and
virtualization switches).

5
|
Inter-switch connections, virtualization switches
4x IB connections (magenta and white connectors, ports
5 and
6) on each virtualization
switch connect directly to the other virtualization switch
in the same datacenter.

Inter-datacenter connections, virtualization
switches
IB LR module links from a virtualization switch in one
datacenter connect to each virtualization switch in the
other datacenter. One single-mode fiber cable is required
per connection.
