Abstract
A fabric access device having a plurality of system interfaces is disclosed. The fabric access device includes a fabric interface configured to receive data from and send data to a switch fabric and a routing circuit configured to send data received on one of the plurality of system interfaces to the switch fabric via the fabric interface. The inclusion of a plurality of system interfaces facilitates a variety of configurations that provide different levels of redundancy and optimize use of available bandwidth.
Claims6
A fabric access system comprising:
- a first fabric access device comprising:
- a first system interface configured to receive data from and send data to a first external system;
- a second system interface;
- and
- a first fabric interface configured to receive data from and send data to a switch fabric;
- a second fabric access device coupled to the first fabric access device, comprising:
- a third system interface configured to receive data from and send data to a second external system;
- a fourth system interface connected to said second system interface of said first fabric access device;
- and
- a second fabric interface configured to receive data from and send data to the switch fabric;
- wherein in the event the second fabric interface or all of its associated links become unavailable for transferring data, the first fabric access device is configured to determine upon receiving data via the first fabric interface whether the data is associated with the first fabric access device or the second fabric access device.
