The Advantages of Object-Based Storage—Secure, Scalable, Dynamic Storage Devices
ثبت نشده
چکیده
This paper introduces the Object-Based Storage Device (OSD) interface, an extension to the SCSI protocol that was developed by the Storage Networking Industry Association (SNIA) over several years and ratified by ANSI in September 2004. This new command set can be carried over the same physical interfaces as SCSI is today, but it represents a major shift of functionality and intelligence into the storage device. Instead of being spread throughout the many layers of a modern storage system, metadata is associated and stored directly with individual data objects, allowing it to be automatically and transparently carried between layers and across devices.

An Efficient Secret Sharing-based Storage System for Cloud-based Internet of Things
Internet of things (IoTs) is the newfound information architecture based on the internet that develops interactions between objects and services in a secure and reliable environment. As the availability of many smart devices rises, secure and scalable mass storage systems for aggregate data is required in IoTs applications. In this paper, we propose a new method for storing aggregate data in Io...
متن کاملTowards Secure Communication for Highly Scalable Mobile Applications in Cloud Computing Systems
Cloud computing is a distributed computing model in which clients pay for computing and data storage resources of a third-party cloud provider. Cloud applications can scale up or down almost instantly to meet real-time computational demands. Despite the economic advantages of a pay-on-demand business model, security remains a paramount concern. Cloud applications by nature must store and retain...
متن کاملUsing Dynamic Thermal Rating and Energy Storage Systems Technologies Simultaneously for Optimal Integration and Utilization of Renewable Energy Sources
Nowadays, optimal integration and utilization of renewable energy sources (RES) are of the most challenging issues in power systems. The wind and solar generation units' maximum production may or may not occur at peak consumption times resulting in non-optimal utilization of these resources. As a solution to this problem, energy storage systems (ESS) are embedded in networks. However, the power...
