Partitioning Between AutoRoute and VSI

In addition to partitioning of resources between VSI and AutoRoute, multiple partitioning allows
sub-partitioning of the VSI space among multiple VSI partitions. Multiple VSI controllers can share the
switch with each other and also with AutoRoute.
The difference between the two types of partitioning is that all the VSI resources are under the control
of the VSI-slave, while the management of AutoRoute resources remains the province of the switch
software.
