With SOI 3.3 Cumulative Update 1 update you can now configure SOI to include the TenantID when CI's are correlated. This is documented on our wiki here:
This can be used if you don't want devices with the same properties to correlate. For example you might have two spectrum connectors pointing to one SOI manager. The connector might be connecting to two different environments where DNS names or IP Addresses might be the same. If you add the TenantID as a property to correlate, only connectors with the same TenantID value will correlate keeping your two environments CI's separate now.
