Patent Application Titled "Low Power Write Journaling Storage System" Published Online

May 27, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventors Sauber, William (Georgetown, TX); Farhan, Munif (Round Rock, TX), filed on November 6, 2012, was made available online on May 15, 2014.

The assignee for this patent application is Dell Products L.P.

Reporters obtained the following quote from the background information supplied by the inventors: "The present disclosure relates generally to information handling systems, and more particularly to low power write journaling storage system for use in an information handling system.

"As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system (IHS). An IHS generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements may vary between different applications, IHSs may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in IHSs allow for IHSs to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, IHSs may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

"Storage systems such as, for example, solid state drives (SSDs), implement various performance optimization and endurance improvement functions that may include, for example, physical space allocation, the mapping of logical blocks to physical storage locations, wear leveling, bad block management, garbage collection, read disturb mitigation, and a variety of other storage system functions known in the art. While these functions provide several positive features for the storage system, supporting such functions requires a full initialization of the storage system and thus consumes power that is not required for basic storage system operations, which delays when the storage system is ready for use and in many cases consumes more power than is necessary.

"Accordingly, it would be desirable to provide an improved storage system."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "According to one embodiment, an information handling system (IHS) includes a system processor; a system memory coupled to the system processor; and a storage system coupled to the system processor and including: a non-volatile solid state memory system; a first processing element that is operable, in a first operational mode, to journal write commands in the non-volatile solid state memory system; and a second processing element that is operable, in a second operational mode that causes the storage system to consume more power than when in the first operational mode, to execute the write commands journaled in the non-volatile solid state memory system.

BRIEF DESCRIPTION OF THE DRAWINGS

"FIG. 1 is a schematic view illustrating an embodiment of an information handling system.

"FIG. 2 is a schematic view illustrated an embodiment of a low power storage system.

"FIG. 3 is a schematic view illustrating an embodiment of a low power function processing element in the storage system of FIG. 2.

"FIG. 4 is a flow chart illustrating an embodiment of a start-up sub-method in a method for providing a low power storage system.

"FIG. 5 is a flow chart illustrating an embodiment of a full function initialization sub-method in a method for providing a low power storage system.

"FIG. 6 is a flow chart illustrating an embodiment of a full function operation sub-method in a method for providing a low power storage system.

"FIG. 7 is a flow chart illustrating an embodiment of a low power initialization sub-method in a method for providing a low power storage system.

"FIG. 8 is a flow chart illustrating an embodiment of a low power operation sub-method in a method for providing a low power storage system."
