StarSwitch2Click to Zoom

StarSwitch2 is a multipurpose StarFabric 4-port switch and dual PMC carrier card in 6U VME form factor. It supports a multi-slot P0-StarFabric point-to-point backplane or chassis-to-chassis connection. P0-StarFabric offers much higher bandwidth than legacy PCI solutions. The StarSwitch supports and scales the G4DSP StarFabric-enabled multiprocessor host.

StarSwitch2's four P0-StarFabric ports can be used singly or in pairs of bundled links for small ultra-high performance systems. Interrupts from the PMC sites are routed either via StarFabric or directly off-board for minimized latency using an interrupt mapper.

StarSwitch2 additionally provides VME access to both PMC sites. StarSwitch2 is available in four ruggedization levels, both air- and conduction-cooled.

  • Four 4x switched StarFabric ports
  • Full StarFabric connectivity
  • VME interface offering VME access to both PMC sites
  • Two independent 64-bit/66 MHz PMC sites
  • Full 64-bit PMC I/O available at P2 from both PMC sites
  • 6U VME form factor
  • Efficient handling of byte-level I/O
  • Air-cooled and conduction-cooled versions available
  • Semi-redundant architecture for restricted maintenance applications
  • Ruggedization Levels
