    • One embodiment relates to a computer system comprising at least one host, at least one object addressable storage (OAS) system and at least one communication medium that couples the at least one host to the at least one OAS system. The at least one OAS system has a plurality of storage devices and stores a plurality of content units on the plurality of storage devices. Each of the at least one host and the at least one OAS system has software that provides a OAS interface so that each one of the content units stored on the OAS system may be identified between the at least one host and the at least one OAS using an object identifier. The computer system maps the object identifier for a first of the plurality of content units to at least one of the plurality of storage devices over at least one first path. In response to a failure that prevents the at least one host from accessing the first content unit via the at least one first path, the computer system is automatically reconfigured to establish at least one previously non-established second path that enables the at least one host to access the first content unit using the object identifier for the first content unit.
    • 一个实施例涉及包括至少一个主机,至少一个对象可寻址存储(OAS)系统和将至少一个主机耦合到至少一个OAS系统的至少一个通信介质的计算机系统。 至少一个OAS系统具有多个存储设备,并且在多个存储设备上存储多个内容单元。 所述至少一个主机和所述至少一个OAS系统中的每一个具有提供OAS接口的软件,使得可以在所述至少一个主机和所述至少一个OAS之间识别存储在所述OAS系统上的每个内容单元,所述内容单元使用 对象标识符。 计算机系统通过至少一个第一路径将多个内容单元中的第一个的对象标识符映射到多个存储设备中的至少一个。 响应于防止至少一个主机经由至少一个第一路径访问第一内容单元的故障,计算机系统被自动重新配置以建立至少一个先前未建立的第二路径,其使能至少一个主机 使用第一内容单元的对象标识符访问第一内容单元。

    • There is disclosed a method for use in managing databases in data storage systems comprising a plurality of nodes. A request is received to provision storage for a specified application intending to use a database. Based on application-awareness, the storage system is provisioned for storing the database in response to receiving the request. Database tables are distributed across the nodes based on a forecasted first I/O profile between application and database. Information is captured in connection with the activity between the application and database. A second I/O profile is determined based on the captured information. The second I/O profile is an actual in-running I/O profile between application and database. The first I/O profile and second I/O profile are compared. The database tables are re-organized on the nodes based on the comparison identifying a discrepancy between first and second I/O profiles such that storage system is rebalanced.
    • 公开了一种用于在包括多个节点的数据存储系统中管理数据库的方法。 接收到一个请求,以便为打算使用数据库的指定应用程序提供存储。 基于应用程序感知,存储系统被提供用于响应于接收到请求而存储数据库。 数据库表根据应用程序和数据库之间预测的第一个I / O配置文件分布在节点之间。 与应用程序和数据库之间的活动相关联地捕获信息。 基于捕获的信息确定第二I / O配置文件。 第二个I / O配置文件是应用程序和数据库之间的实际正在运行的I / O配置文件。 比较第一个I / O配置文件和第二个I / O配置文件。 基于识别第一和第二I / O配置文件之间的差异的比较,数据库表在节点上重新组织,使得存储系统被重新平衡。

    • Methods, a system, and a program product for use in managing data storage is disclosed. In an embodiment, a method, system, and program product comprises receiving content via an object based storage interface to a data storage system; generating a database insert operation for an object derived from the content, the object having a generated object identifier; and using the database entry operation, storing data associated with the object in a shared-nothing database located within the data storage system, wherein the shared-nothing database is enabled to perform parallel processing across multiple independent nodes.In another embodiment, a method comprises receiving a delete command for an object via an object based interface to a data storage system; generating a database delete operation for the object based on the delete command; and using the database delete operation, deleting data associated with the object in a shared-nothing database located within the data storage system, wherein the shared-nothing database is enabled to perform parallel processing across multiple independent nodes.In yet another embodiment, a method comprises receiving a search command via an object based interface to a data storage system; generating a database query based on the search command; and using the database query, querying a shared-nothing database located within the data storage system, wherein the shared-nothing database is enabled to perform parallel processing across multiple independent nodes.
    • 公开了用于管理数据存储的方法,系统和程序产品。 在一个实施例中,方法,系统和程序产品包括经由基于对象的存储接口接收内容到数据存储系统; 为从所述内容导出的对象生成数据库插入操作,所述对象具有生成的对象标识符; 以及使用所述数据库输入操作,将与所述对象相关联的数据存储在位于所述数据存储系统内的无共享数据库中,其中所述无共享数据库能够跨多个独立节点执行并行处理。 在另一个实施例中,一种方法包括通过基于对象的接口向数据存储系统接收对象的删除命令; 基于删除命令生成对象的数据库删除操作; 以及使用所述数据库删除操作,删除位于所述数据存储系统内的无共享数据库中与所述对象相关联的数据,其中所述无共享数据库能够跨多个独立节点执行并行处理。 在另一个实施例中,一种方法包括经由基于对象的接口向数据存储系统接收搜索命令; 基于搜索命令生成数据库查询; 以及使用数据库查询,查询位于数据存储系统内的无共享数据库,其中无共享数据库能够跨多个独立节点执行并行处理。

    • In one embodiment of the invention, a utility may be installed (e.g., by a system administrator) on a storage system. The utility may read content units on the storage system that are stored in one data format, and convert the content units to a second data format. In one embodiment, in response to a read request for a content unit, a data format in which to return the content unit may be selected and the content unit may be returned in that data format. In another embodiment, mapping information may be created that specifies in which data format a content unit should be returned in response to a request for the content unit. The mapping information may be stored either on the storage system that stores the content unit, the computer requesting access to the content unit, or any other computer or device in the computer system.
