Modern disk-storage systems have to accomplish the requirements of a variety of application classes. Applications that process continuous-media data such as video and audio streams require the storage system to guarantee sustained bandwidths. Interactive applications demand the storage system to ensure bounded response times, posing timing constraints on the execution of individual disk request...

There are available today many data storage devices that serve the diverse application requirements of the consumer, professional entertainment, and computer data processing industries. Storage technologies include semiconductors, several varieties of optical disk, optical tape, magnetic disk, and many varieties of magnetic tape. In some cases, devices are developed with specific characteristic...

caching in an enterprise storage system S. Seshadri P. H. Muench L. Chiu I. Koltsidas N. Ioannou R. Haas Y. Liu M. Mei S. Blinick A software defined storage environment is one in which logical storage resources and services are completely abstracted from physical storage systems. Therefore, not only can storage resources cross physical boundaries, but they can also be defined by software and pr...

Concurrent Big Data applications often require high-performance storage, as well as ACID (Atomicity, Consis­ tency, Isolation, Durability) transaction support. Although blobs (binary large objects) are an increasingly popular storage model for such applications, state-of-the-art blob storage systems offer no transaction semantics. This demands users to coordinate data access carefully in order ...

Applications are deployed upon deep, diverse storage stacks that are constructed on-demand. Although many storage stacks share a common API to allow portability, application behavior differs in subtle ways depending upon unspecified properties of the underlying storage stack. Currently, there is no way to test whether an application will behave correctly on a given storage stack: corruption or ...

The ubiquity of the cloud computing allows the mobile devices to connect and use the traditional cloud computing services [1]. However, unlike the normal computing machines, the mobile devices are resource constrained. The precincts of low processing power, less storage capacity, limited energy, and the capricious internet connectivity does not allow the compute and storage mandating applicatio...
