Abstract
A network flow switch system that uses an active flow switch and a passive flow switch in conjunction to achieve redundancy or failover. The flow switches switch information between network components via Y-cables that allow both flow switches to remain simultaneously connected to the network devices. A failover link connects the flow switches together and allows the passive flow switch to monitor the status of the active flow switch. The active flow switch performs all switching while the active flow switch is operational.
Claims32
A network flow switching system for routing packets between a plurality of servers and a plurality of network devices, the system comprising:
- a plurality of Y-cables, each of the Y-cables being connected to either one of the servers or one of the network devices;
- a first flow switch connected to the plurality of Y-cables;
- and
- a second flow switch connected to the plurality of Y-cables and to the first switch;
- wherein packets are routed between the servers and the network devices via the first flow switch if the first flow switch is active and the packets are routed between the servers and the network devices via the second flow switch if the first flow switch is passive.
A method for routing packets between a plurality of servers and a plurality of network devices, the method comprising:
- routing the packets between the servers and the network devices via a plurality of Y-cables, each of the Y-cables connecting either one of the servers or one of the network devices to the first flow switch and the second flow switch;
- routing packets between the servers and the network devices via a first flow switch if the first flow switch is active;
- and
- routing the packets between the servers and the network devices via the second flow switch if the first flow switch is passive.
A computer readable storage medium comprising computer instructions for:
- routing packets between a plurality of servers and a plurality of network devices via a plurality of Y-cables, each of the Y-cables connecting either one of the servers or one of the network devices to the first flow switch and the second flow switch;
- wherein the first flow switch routes packets between the servers and the network devices if the first flow switch is active and the second flow switch routes the packets between the servers and the network devices if the first flow switch is passive.
