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。与传统存储架构相比，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，但也引入了额外的挑战，特别是在可管理性方面。在这个提案中，描述了WiND项目（威斯康星网络磁盘），其目标是开发构建一个真正可管理的网络附加存储系统所需的软件技术。可管理性的关键是适应性。在传统系统中，这种调整是由人类管理员执行的。未来的存储系统必须自己适应，这样做可以减少对人工干预的需求。WiND系统将优雅而有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会自动处理向系统添加新的异构磁盘、现有磁盘的故障以及客户端工作负载的变化。在该提案中，开发了WiND的三个特定子领域：SToRM的自适应数据布局和访问，通过云的自适应缓存以及底层信息基板。

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.
