EIA 02-24439Grunwald, Dirk C.University of ColoradoTitle:CISE RR: Instrumentation Support for Very Large Data Stores This proposal, designing a system using Massive Arrays of Idle Disks (MAID) as a replacement for data centers that would normally use tape archives, will utilize infrastructure in the design and fabrication of an alternative design to conventional mass storage systems that attempt to address critical data center issues such as data density (i.e., reduced floor space), reliability, power efficiency, and manageability. Using a combination of commodity disk drives, power management, distributed control, and caching hierarchy, the researcher claims that the MAID storage organization provides storage densities matching or exceeding those of tape libraries with performances similar to disk arrays. Studies have shown that through a combination of effective power management of individual drives and caching, this performance can be achieved using a very small power envelope. The large backing store will be composed of inexpensive IDE disks that, rather than spinning, are allowed to go idle when not in use. The main goal consists of replacing conventional tape archival storage with an alternative technology at significantly reduced power cost. The experimental testbed consists of 120 IDE drives, each of which holds 160GB of data for a total of 19.2TB of online storage, of which approximately 160TB would be available once redundancy is addressed. The infrastructure also includes 120 drive enclosures that connect commodity IDE drives to 1394 (firewire) I/O networks.

EIA 02-24439Grunwald, Dirk C.科罗拉多大学标题：CISE RR：对超大型数据存储的仪器支持该提案设计了一个使用大规模空闲磁盘阵列 (MAID) 的系统来替代通常使用磁带存档的数据中心，将利用基础设施来设计和制造传统海量存储系统的替代设计，试图解决数据中心的关键问题，例如数据密度（即减少占地面积）、可靠性、电源效率和可管理性。研究人员声称，MAID存储组织结合了商品磁盘驱动器、电源管理、分布式控制和缓存层次结构，提供了与磁带库相当或超过磁带库的存储密度，而性能与磁盘阵列相似。研究表明，通过将单个驱动器的有效电源管理与缓存相结合，可以使用非常小的功率包络来实现这种性能。大型后备存储将由廉价的 IDE 磁盘组成，这些磁盘在不使用时可以闲置，而不是旋转。主要目标包括用替代技术取代传统的磁带档案存储，并显着降低电力成本。实验测试台由 120 个 IDE 驱动器组成，每个驱动器可容纳 160GB 数据，总共 19.2TB 在线存储，一旦解决冗余问题，其中大约 160TB 可用。该基础设施还包括 120 个驱动器机箱，用于将商用 IDE 驱动器连接到 1394（火线）I/O 网络。
