Description
Distributed systems are gaining popularity as they fill the need of next generation systems. Multiprocessor systems provide not only the ability to increase processing bandwidth, but also allow greater system reliability through host failover.
The use of non-transparent bridges in PCI systems to support intelligent adapters in enterprise systems and multiple processors in embedded systems is well established. In these systems, the non-transparent bridge functions as gateway between the local subsystem and the backplane.
Such applications can be ported to PCI Express by the use of non-transparentt bridges, with the non-transparent bridge integrated into a PCI Express switch in place of one of the transparent bridges. Switch with a single [port configured to operate in non-transparent mode supports intelligent adapter and dual-host models.
Our experience of establishing non-transparent bridging in MTCA system will be presented.
