EMC Assigned Three Patents

Environment management interface
for management of heterogeneous storage environment

EMC Corp., Hopkinton, MA, has been assigned a patent (8,326,882) developed by six co-inventors for an "environment management interface for management of a heterogeneous storage environment."

The co-inventors are Munish Desai, Shrewsbury, MA, Tara Halwes, Boston, Bruce Rabe, Dedham, MA, Neil Schutzman, Marlborough, MA, Scott Von Rhee, Boston, and Nancy Welch, Charlton, MA.

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A heterogeneous data storage environment includes a first and second data storage system where the first data storage system includes management functionalities that are distinct from the management functionalities included by the second data storage system. A storage system management device is displays an environment management interface that dynamically changes based upon a user’s need to manage either the first or second storage system. For example the storage system management device provides a default environment management interface for the first data storage system that includes a custom management display that allows the user to access the management functionalities associated with the first data storage system. The storage system management device dynamically changes the content of the environment management interface to provide a custom management display associated with the user selection of a second data storage system."

The patent application was filed on Sept. 25, 2009 (12/567,031).

Network address translation auto-discovery
in data storage networks

EMC, Hopkinton, MA, has been assigned a patent (8,326,919) developed by five co-inventors for a "network address translation auto-discovery in data storage networks."

The co-inventors are Anirudh Takkallapally, Natick, MA, Scott Joyce, Foxboro, MA, Sreenath Rajagopal, Natick, MA, Bruce Rabe, Dedham, MA, and Greg Lazar, Upton, MA.

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Embodiments of the invention relate to a method for discovering a network address translation (NAT) network connection with a data storage system. The method includes establishing, by a client device, a network connection with the data storage system via a target network address associated with the data storage system, retrieving over the network connection, by the client device, a set of private network addresses associated with a set of storage processors of the data storage system, comparing, by the client device, each private network address of the set of private network addresses associated with the set of storage processors with the target network address, and when the target network address is absent from the set of private network addresses associated with the set of storage processors as a result of the comparison, detecting, the network connection as being configured as a NAT mode network connection with the data storage system."

The patent application was filed on Dec. 22, 2009 (12/644,237).

Managing data objects of storage system

EMC, Hopkinton, MA, has been assigned a patent (8,316,064) developed by Windsor W. Hsu, San Jose, CA, for a "method and apparatus for managing data objects of a data storage system."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Techniques for managing data objects of a data storage system are described herein. According to one embodiment, a perfect hash function is generated for data objects stored in a data storage system. For each of the data objects, a hash operation is performed using the perfect hash function to indicate whether the respective data object is alive. Resources associated with the respective data object is reclaimed if it is determined that the respective data object is not alive based on a result of the hash operation using the perfect hash function, where the reclaimed resources are released back to the data storage system as free resources. Other methods and apparatuses are also described."

The patent application was filed on Aug. 25, 2008 (12/198,021).
