EMC Assigned Five Patents

Method and system of providing object location metadata
cookies in a federated content addressable storage system

EMC Corp., Hopkinton, MA, has been assigned a patent
(8,296,511) developed by Mark O’Connell,
Westborough, MA, and Tom Teugels, Schoten, Belgium, for a "method and system
of providing object location metadata cookies in a federated content addressable
storage system."

The abstract of the patent published by the U.S. Patent
and Trademark Office states: "Managing data on a federated CAS system includes
determining a group of objects to be stored on a single CAS system of the federated
CAS system, obtaining a cookie corresponding a particular one of the CAS systems
of the federated CAS system in response to initially writing at least one object
of the group of objects, where the at least one object is written to the particular
one of the CAS systems, and providing the cookie in connection with writing objects
of the group of objects following initially writing at least one object of the group
of objects. The cookie causes the objects to be written to the particular one of
the CAS systems. The cookie may be provided by at least one router that maintains
the federated CAS system, which may be separate from both a processing device and
the particular one of the CAS systems."

The patent application was filed on June 26, 2009 (12/459,194).

Techniques for providing access to video data using
a network attached storage device

EMC Corp., Hopkinton, MA, has been assigned a patent
(8,300,098) developed by four co-inventors
for "techniques for providing access to video data using a network attached
storage device."

The co-inventors are Brian Gruttadauria, Sutton, MA,
Shyam Sareen, Bedford, MA, Joseph Frank, Boulder, CO, and Paul Malenfant, Shrewsbury,
MA.

The abstract of the patent published by the U.S. Patent
and Trademark Office states: "An improved technique provides access to video
data using a network attached storage (NAS) device. The technique involves detecting
access to a video camera from the NAS device through a network, and receiving a
video store command from a user workstation through the network. The video store
command directs the NAS device to store video data provided by the video camera
to the NAS device through the network. The technique further involves storing the
video data provided by the video camera to the NAS device through the network in
response to the video store command."

The patent application was filed on Sept. 16, 2008 (12/211,235).

Managing files using layout storage objects

EMC Hopkinton, MA, has been assigned a patent (8,296,340)
developed by four co-inventors for "managing files using layout storage objects."

The co-inventors are Fernando Oliveira, Sudbury, MA,
Stephen Fridella, Watertown, MA, Rossen Dimitrov, Nashua, NH, and Patrick Eaton,
Arlington, MA.

The abstract of the patent published by the U.S. Patent
and Trademark Office states: "Managing file objects in a data storage system
includes providing a plurality of metadata servers, each metadata server having
information for only a subset of file objects in the storage system, each subset
for each of the metadata servers being less than a total number of file objects
for the system and includes providing at least one metadata location server, where
an entity accessing a specific file object of the system determines which of the
metadata servers contains data for the specific file object by first accessing the
at least one metadata location server. Information for the subset of file objects
may include a table having file identifiers and metadata location information. The
metadata location information may point to data storage for a metadata object for
a file."

The patent application was filed on May 19, 2011 (13/111,285).

Storage system initialization utility

EMC Corp., Hopkinton, MA, has been assigned a patent
(8,301,739) developed by Sriram Krishnan,
Shrewsbury, MA, Andreas Bauer, Boxborough, MA, and Greg W. Lazar, Upton, MA, for
a "storage system initialization utility."

The abstract of the patent published by the U.S. Patent
and Trademark Office states: "Methods for initializing a storage system over
a network are described. A server initialization utility operates on each of several
storage processing units. A client initialization utility operates on a client computing
device. The client initialization utility and server initialization utility communicate
via a network coupled to the client computing device and the storage processing
units. The client initialization utility is used to initialize parameters for each
storage processing unit via communication with the corresponding server initialization
utility. The client initialization utility is further used to discover array and
storage processing identification information. The client and server initialization
utilities communicate via exchange of UDP broadcast datagrams."

The patent application was filed on Dec. 23, 2004 (11/021,355).

Security and licensing with application aware storage

EMC Corp., Hopkinton, MA, has been assigned a patent
(8,302,201) developed by four co-inventors
for a "security and licensing with application aware storage."

The co-inventors are Uday K. Gupta, Westford, MA, Andreas
L. Bauer, Boxborough, MA, Stephen J. Todd, Shrewsbury, MA, and Mark A. Parenti,
Milford, NH.

The abstract of the patent published by the U.S. Patent
and Trademark Office states: "Described are techniques for processing a data
storage configuration request for an application. The data storage configuration
request is received from a requester. A first user level of a plurality of user
levels at which the data storage configuration request is made by the requester
is determined. Each user level is associated with a different level of abstraction
with respect to processing performed in the data storage system for implementing
the data storage configuration request. The data storage configuration request is
serviced. Servicing the request includes determining whether to perform the data
storage configuration request in accordance with security criteria defining, for
each of the plurality of user levels, permitted operations that may be performed
for different requesters in connection with the data storage configuration request."

The patent application was filed
on Sept. 28, 2007 (11/906,131).
