The Session Connections window shows how many iSCSI Connections are active and the type of load
balance used. For all iSCSI Sessions there will be at least one ‘leading connection’.
iSCSI connections can be added and removed at any time, all apart from the leading connection, which can
only be removed when the iSCSI Session is logged off.
The Load balance policy specifies how the data is distributed over multiple connections. The main policies
that should be used are ‘Round Robin’ and ‘Fail Over Only’.
Round Robin will utilize all connections for data and evenly distribute the data.
Fail Over Only will use the Leading connection for data transfer. If a connection should go down then the
data transfer shall switch on one of the other connections.
For most purposes Round Robin will provide the greatest performance increase.
If you have been experiencing a performance decrease when transferring data to more than one device
using multiple connections, please refer to the trouble shooting guide.
