Active Object Storage to Enable Scalable and Reliable Parallel File Systems

处理器性能的提高和成本的降低使得诸如磁盘驱动器之类的外围设备的系统智能得以提高。磁盘的这种计算能力导致了基于对象的存储的发展，其中一些文件系统功能被转移到磁盘。计算能力还可以在存储节点处实现计算，所述存储节点被称为活动磁盘或活动存储。 这种主动存储计算作为一种机制，使并行计算使用分布式存储nodes.This研究的重点是使用这些主动磁盘的并行文件系统和存储管理。 目前正在开发一个建立在标准化的对象存储设备规范基础上的功能性主动存储系统结构。 该架构支持多种执行引擎，允许多种编程语言和模型。 使用这种主动对象存储体系结构，机制，以提高整体的可扩展性和大规模系统的可靠性正在调查。 此外，主动和对象存储用于实现可定制和可扩展的文件系统，包括自主（自配置和自管理）存储以及应用感知存储，使得存储可以针对应用和用户需求进行优化。

The increasing performance and decreasing cost of processors has enabled increased system intelligence at peripherals such as disk drives. This computational capability at the disk has led to the development of object-based storage whereby some of the file system functionality is moved to the disk. The computation capability can also enable computation at the storage node in what has been called active disks or active storage. This active storage computation serves as a mechanism to enable parallel computation using distributed storage nodes.This research focuses on the use of these active disks for parallel file system and storage management. A functional active storage system architecture built on the standardized object-storage device specification is being developed. The architecture supports a variety of execution engines allowing multiple programming languages and models. Using this active object storage architecture, mechanisms to improve overall scalability and large-scale system reliability are being investigated. In addition, active and object storage are used to enable customizable and extensible file systems including autonomic (self-configuring and self-managing) storage as well as application aware storage such that the storage can be optimized for application and user needs.
