A switch fabric system comprises a first chassis for receiving a plurality of line cards each having a plurality of ports and at least two switch fabric cards wherein each line card comprises a plurality of link ports for linking the line card with the switch fabric card. Each switch fabric card provides a switching bandwidth. The system comprises a management unit for managing the traffic on the switch fabric cards wherein the management unit removes the traffic from one switch fabric card if the one switch fabric card is to be removed while the other switch fabric card operates and transfers the traffic to the other switch fabric card.

System and method for expansion of computer network switching system without disruption thereof

In one aspect, the invention is a tuned stub, SCSI topology comprising a SCSI bus, a breakout node on the SCSI bus, an external SCSI connector on the SCSI bus at a first point defined by a first propagation delay; an internal SCSI connector on the SCSI bus at a second point defined by a second propagation delay, the first and second propagation delays being substantially equal; a SCSI adapter electrically tapping the breakout node; and a terminator electrically tapping the breakout node.

Method and apparatus implementing a tuned stub SCSI topology

A method and apparatus for adding inductance is disclosed. Inductance may be added to a transmission line coupled to a printed circuit board to increase the inductance associated with a transmission line by utilizing ferromagnetic materials.

Method and apparatus for adding inductance to printed circuits

Embodiments of the present invention may provide for high-density and high speed interconnections while maintaining reduced signal interference. In some embodiments, differential signals are organized in connectors such that differential signal pairs are orthogonal to each other. In other embodiments, differential signal tri-conductor sets may be oriented such that they are generally orthogonal to each other. The orthogonal contact organization may provide for reduced coupling between differential signals.

Low cost high speed connector

A tuned stub, SCSI topology is disclosed. More particularly, a SCSI bus comprises a plurality of SCSI load stubs, a pair of SCSI terminators, a plurality of traces electrically connecting the SCSI load stubs between the SCSI terminators, and a plurality of tuning stubs. The tuning stubs are positioned at predetermined locations on the plurality of traces and have predetermined lengths such that they are capable of filtering noise on the SCSI bus.
