Symantec Assigned Two Patents

Symantec Operating Corp., Mountain View, CA, has been assigned a patent (8,732,354) developed by Tommi Salli, Mountain View, CA, for a “method and apparatus for controlling access to a SAN.”
 
The abstract of the patent published b the U.S. Patent and Trademark Office states: “A method and apparatus for controlling access to a storage area network among a group of hosts in a distributed computing environment. A host requests access to the storage area network by issuing an input/output request, and the input/output request is intercepted at the dynamic multipath (DMP) layer. The DMP layer checks the input/output request against an access control list. The DMP layer can grant or deny the input/output request from the host system. If the input/output request is granted, then the DMP layer passes on the input/output request to the HBA driver layer and the host is allowed to access the storage area network. If the request to access the storage area network is denied, the DMP management layer can initiate an appropriate response, such as a security procedure or generation of an error message alerting a user the request has been denied.”

The patent application was filed on Sept. 30, 2005 (11/240,188).
