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磁盘驱动器等外设的系统智能得以提高。磁盘上的这种计算能力导致了基于对象的存储的发展，从而将一些文件系统功能移到了磁盘上。计算能力还可以在被称为活动磁盘或活动存储的存储节点上进行计算。这种活动存储计算作为一种机制，可以使用分布式存储节点实现并行计算。本研究的重点是在并行文件系统和存储管理中使用这些活动磁盘。基于标准化对象存储设备规范的功能主动存储系统架构正在开发中。该体系结构支持多种执行引擎，允许使用多种编程语言和模型。利用这种主动对象存储体系结构，研究了提高整体可伸缩性和大规模系统可靠性的机制。此外，活动存储和对象存储用于启用可定制和可扩展的文件系统，包括自主（自配置和自管理）存储以及应用程序感知的存储，以便可以针对应用程序和用户需求对存储进行优化。

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.
