DDN Assigned Two Patents

Data migration between high performance computing architectures and file system using distributed parity group information structures with non-deterministic data addressing
DataDirect Networks, Inc., Chatsworth, CA, has been assigned a patent (9,477,551) developed by Piszczek, Michael J., Laurel, MD, Cope, Jason M., Highland, MD, Nowoczynski, Paul J., Brooklyn, NY, and Uppu, Pavan Kumar, Woodbine, MD, for a “method and system for data migration between high performance computing architectures and file system using distributed parity group information structures with non-deterministic data addressing.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The present invention is directed to data migration, and particularly, Parity Group migration, between high performance data generating entities and data storage structure in which distributed NVM arrays are used as a single intermediate logical storage which requires a global registry/addressing capability that facilitates the storage and retrieval of the locality information, (metadata) for any given fragment of unstructured data and where Parity Group Identifier and Parity Group Information, (PGI) descriptors for the Parity Groups’ members tracking, are created and distributed in the intermediate distributed NVM arrays as a part of the non-deterministic data addressing system to ensure coherency and fault tolerance for the data and the metadata. The PGI descriptors act as collection points for state describing the residency and replay status of members of the Parity Groups.“

The patent application was filed on December 1, 2014 (14/556,571).

Data storage system with active power management and method for monitoring and dynamical control of power sharing between devices in data storage system
DataDirect Networks, Inc., Chatsworth, CA, has been assigned a patent (9,477,279) developed by Piszczek, Michael J., Laurel, MD, Cope, Jason M, Highland, MD, and Uppu, Pavan Kumar, Woodbine, MD, for a “data storage system with active power management and method for monitoring and dynamical control of power sharing between devices in data storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A data storage system is implemented with an active power monitoring and control performed by a control node elected among a number of nodes. A real-time power monitoring information is supplied to the control node from, a power monitoring logic residing at each device in the system. The devices in the data storage system are pre-allocated with respective individual power budgets which are below the maximum power usage thereof. The power budgets of all the equipment cumulatively constitute a power budget assigned to the group of equipment. The control node controls dynamically and in real time power sharing between the plurality devices so that the devices with required power usage below the pre-allocated power budget can share their extra power credits with devices which are in need for extra power for performing its operation. The control node provides sharing of the power among the equipment in the data storage system with a goal of avoiding exceeding of the cumulative power budget assigned for the entire system or the cluster of the equipment.“
