Symantec Assigned Two Patents

Efficient sequential logging
on caching-enabled storage devices

Symantec Corp., Mountain View, CA, has been assigned a patent (8,380,962) developed by four co-inventors for "systems and methods for efficient sequential logging on caching-enabled storage devices."

The co-inventors are Ajay Kumar, Rajesh Chepuri, Shailesh Marathe, Maharashtra, India, and Niranjan Pendharkar, Pune, India.

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A computer-implemented method for efficient sequential logging on caching-enabled storage devices may include 1) identifying a storage device with a cache, 2) allocating space on the storage device for a sequential log, 3) calculating a target size for the sequential log based at least in part on an input/output load directed to the sequential log, and then 4) restricting the sequential log to a portion of the allocated space corresponding to the target size. Various other methods, systems, and computer-readable media are also disclosed."

The patent application was filed on Aug. 16, 2010 (12/856,985).

Using cloud-based storage to optimize storage operations

Symantec Corp., Mountain View, CA, has been assigned a patent (8,370,312) developed by Sanjay Sawhney, Cupert, CA, Hemant Puri, Milpitas, CA, and Hans Van Rietschote, Sunnyvale, CA, for "systems and methods for using cloud-based storage to optimize data-storage operations."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A computer-implemented method for using cloud-based storage to optimize data-storage operations may include: 1) receiving a request from a client device for instructions or directions for storing a data object, 2) accessing a data-placement policy that contains criteria for identifying storage systems suitable for storing the data object, 3) identifying, based at least in part on the data-placement policy, a plurality of storage systems for storing the data object, at least one of the storage systems including a third-party Internet-based storage system, and then 4) directing the client device to store the data object on the identified storage systems."

The patent application was filed on Sept. 15, 2009 (12/560,374).
