Bridge or Gateway Functionality
The SG2010 is a multi-function device that operates as bridge or a gateway, as
shown in Figure 13.
FIGURE 13. Conceptual View of SG2010’s Multi-function Support
Operating as a bridge, the SG2010 transparently bridges PCI traffic to and from the
StarFabric. It supports legacy address-routed traffic, providing full compatibility
with your existing PCI application. This means you can deploy StarFabric without
making changes to your existing legacy application.
As a gateway, the SG2010 operates like a non-transparent bridge to support
advanced StarFabric features, including address translation between local remote
buses, path routing, multicast routing, QoS, automatic failover, and advanced inter-
rupt support.
You can select bridge or gateway operation by manually setting DIP Switches on
the Aurora Host Interface Card (HIC). You can use the same DIP switches to man-
ually select whether the SG2010 operates as a Root or Leaf node in your StarFab-
ric, or you can let the StarFabric automatically assign Root and Leaf operation in
your application. Root and Leaf are operating modes that control the behavior of
devices in the switch fabric.
