Patent
Method and system for data placement in a hard disk drive based on access frequency for improved IOPS and utilization efficiency
TL;DR: In this paper, the authors present a write operation in a shingled magnetic recording device, where the data with the highest access-frequency is written to an outer track and the data at a current write pointer location of the selected track, thereby facilitating an enhanced data placement for subsequent access in the storage device.
Patent
Method and system for enhancing flash translation layer mapping flexibility for performance and lifespan improvements
TL;DR: In this paper, a flash translation layer is used to map the first logical block address of the first page of the data to the first physical block address, where the destination page is a first available page of a block.
Patent
Method and system for distributed storage using client-side global persistent cache
Shu Li,Jianjian Huo +1 more
TL;DR: In this paper, the authors present a system for facilitating a distributed storage system, where the system receives, by a first client-serving machine, a first request to write data and writes the data to a first persistent cache associated with the first client serving machine, wherein a persistent cache includes nonvolatile memory.
Patent
Method and system for user-space storage I/O stack with user-space flash translation layer
TL;DR: In this article, the authors present a system that facilitates a user-space storage I/O stack, where the flash translation layer module is located between the file system and a block device driver in the user space.
Patent
Method and system for facilitating atomicity assurance on metadata and data bundled storage
TL;DR: In this article, a data buffer is used for storing data and metadata associated with a preceding I/O request of the first stream of data in a data stream, where the residual data associated with previous I/Os are stored in the data buffer.

Journal ArticleDOI
A study of practical deduplication
TL;DR: In this paper, the authors collected file system content data from 857 desktop computers at Microsoft over a span of four weeks and analyzed the data to determine the relative efficacy of data deduplication, particularly considering whole file versus block-level elimination of redundancy.
Patent
System and method for organizing data to facilitate data deduplication
TL;DR: In this article, a technique for organizing data to facilitate data deduplication includes dividing a block-based set of data into multiple “chunks”, where the chunk boundaries are independent of the block boundaries (due to the hashing algorithm).
Patent
Assimilation of foreign LUNS into a network storage system
TL;DR: In this article, the authors define several types of data containers, including "regions", "logical extents" and "slabs", which can be defined from a heterogeneous pool of physical storage devices.
Patent
Computer program, apparatus, and method for managing data
Masahisa Tamura,Yasuo Noguchi,Kazutaka Ogihara,Tetsutaro Maruyama,Yoshihiro Tsuchiya,Takashi Watanabe,Tatsuo Kumano,Kazuichi Oe +7 more
TL;DR: In this paper, a deduplication-eligible data unit detection module detects a data unit that is found to be not in compliance with a data access grace period after the last write time has expired.
Patent
Data access request monitoring to reduce system resource use for background operations
TL;DR: In this article, the authors propose a proxy that can provide processing services for access requests to initialized and uninitialized storage regions, where the proxy stores write information in a write metadata repository, and if the write is requested for an address in an initialized storage region of the storage system, the proxy performs a write to the initialized region based on region information provided by the proxy.
