Robust Adaptive Network-Attached Storage

随着网络连接存储设备的出现，存储行业的基本要素正在发生根本性的变化。与传统存储体系结构相比，由网络连接驱动器组成的存储系统提供了许多潜在的优势，但也带来了额外的挑战，特别是在可管理性方面。在这份提案中，描述了WIND项目(威斯康星州网络磁盘)，该项目的目标是开发所需的软件技术，以建立一个真正可管理的网络连接存储系统。在传统系统中，这类操作由人工管理员执行。未来的存储系统必须自我适应，并在这样做的同时减少对人工干预的需求。WIND系统将优雅而高效地适应环境的变化，减轻管理负担，并为各种客户增加存储的灵活性。特别是，WIND将自动处理系统中新的异类磁盘的添加、现有磁盘的故障以及客户端工作负载的变化。在该方案中，开发了三个特定的风子区域：自适应数据布局和风暴访问、通过云的自适应缓存和底层信息基础。

The basic elements of the storage industry are in the midst of radical changewith the advent of network-attached storage devices. Storage systems comprisedof network-attached drives provide many potential advantages over traditionalstorage architectures, but also introduce additional challenges, particularlyregarding manageability. In this proposal, the WiND project (WisconsinNetwork Disks) is described, which has the goal of developing the softwaretechniques required to build a truly manageable network-attached storagesystem.The key to manageability is adaptation. In traditional systems, suchadaptation is performed by a human administrator. Future storage systems mustthemselves adapt, and in doing so, reduce the need for manualintervention. The WiND system will gracefully and efficiently adapt to changesin the environment, reducing the burden of administration and increasing theflexibility of storage for an eclectic range of clients. In particular, WiNDwill automatically handle the addition of new heterogeneous disks to thesystem, the failure of existing disks, and changes in client workload. Withinthis proposal, three specific sub-areas of WiND are developed: adaptive datalayout and access with SToRM, adaptive caching via Clouds, and the underlyinginformation substrate.
