Fibre channel dynamic zoning
First Claim
Patent Images
1. A method, comprising:
- detecting an arbitration process between a first host and a second host for a first storage resource, the first storage resource included in a first zone in a fibre channel storage area network;
monitoring messages between the first host and the first storage resource by snooping messages between the first host and the first storage resource;
selecting the first host using an arbitration algorithm;
updating zoning information associated with the first host by dynamically assigning the first host to the first zone and excluding the second host from the first zone;
propagating updated zoning information through the fibre channel storage area network.

Abstract
Zone information is automatically and dynamically configured and managed in a fiber channel storage area network upon detection of network events. Some examples of events that trigger automatic dynamic zone updates include virtual port creation, intrusion/anomaly detection, arbitration decision completion, misconfiguration detection, and device malfunction. The newly created/updated zones are propagated through the fiber channel fabric and provide access control.

10. A system, comprising:
-
an interface configured to detect an arbitration process between a first host and a second host for a first storage resource, the first storage resource included in a first zone in a fibre channel storage area network; a processor configured to monitor messages between the first host and the first storage resource by snooping messages between the first host and the first storage resource, select the first host using an arbitration algorithm, and update zoning information associated with the first host by dynamically assigning the first host to the first zone and excluding the second host from the first zone; wherein the interface is further configured to propagate updated zoning information through the fibre channel storage area network. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
