    • The invention relates to a data storage computer tool that comprises a correspondence module (40) connected to storage units (38), said correspondence module (40) including a correspondence function for determining at least a first and a second storage address from a virtual address received at the input, characterised in that the correspondence function is adapted so that: the tool includes a rule for distributing at least a portion of the storage addresses into a working group and a selected number of failure groups on the basis of a failure tolerance criterion, said rule implying that at least one of the storage units includes storage addresses associated with the work group and storage addresses associated with at least one failure group; the tool further maintains a resilience table containing inputs each associating a failure group and a storage unit based on the failure state of said storage unit, said correspondence function being adapted for allocating by blocks at least a portion of the virtual addresses to storage addresses belonging to the work group by carrying out a hashing of the virtual addresses on the work group; and said correspondence function being adapted for allocating, in case of failure of a storage unit, at least a portion of the virtual addresses associated with the storage addresses on said storage unit, to storage addresses belonging to a failure group to which the failing storage unit is associated in the resilience table.
    • 本发明涉及一种数据存储计算机工具，其包括连接到存储单元（38）的对应模块（40），所述对应模块（40）包括用于从虚拟地址确定至少第一和第二存储地址的对应功能 其特征在于，所述通信功能被适配成使得：所述工具包括用于基于故障容限标准将所述存储地址的至少一部分分发到工作组和所选择的故障组数的规则 所述规则意味着至少一个存储单元包括与工作组相关联的存储地址和与至少一个故障组相关联的存储地址; 所述工具进一步维护包含输入的弹性表，所述输入各自基于所述存储单元的故障状态来关联故障组和存储单元，所述对应功能适于通过块将所述虚拟地址的至少一部分分配给属于 工作组通过对工作组上的虚拟地址进行散列; 并且所述通信功能适于在存储单元发生故障的情况下将与所述存储单元上的存储地址相关联的虚拟地址的至少一部分分配给属于故障组的故障组的存储地址，故障存储单元 与弹性表相关联。

    • Computer tool for storing data, comprising a matching module (40) that is connected to storage units (38) and is designed to determine a match between virtual addresses and physical addresses in the storage units, each virtual address being assigned to at least two storage addresses. Said computer tool is characterized in that the matching module maintains a first table containing data for identifying faulty storage units as well as a second table containing data for modifying blocks of virtual addresses. Furthermore, the computer tool also comprises a recovery unit (406) which is designed, once a faulty storage unit has been restored, to update the storage addresses of said storage unit by calling the matching module by means of virtual addressed extracted from the second table on the basis of the data of the first table.
    • 用于存储数据的计算机工具，包括连接到存储单元（38）的匹配模块（40），并被设计为确定存储单元中的虚拟地址和物理地址之间的匹配，每个虚拟地址被分配给至少两个存储器 地址。 所述计算机工具的特征在于，匹配模块维护包含用于标识错误存储单元的数据的第一表以及包含用于修改虚拟地址块的数据的第二表。 此外，计算机工具还包括恢复单元（406），该恢复单元（406）一旦故障存储单元已被恢复，就通过借助从第二表提取的虚拟寻址调用匹配模块来更新所述存储单元的存储地址 根据第一个表的数据。

    • A computer-based system comprises several computer-based facilities termed nodes interconnected in a network, - storing nodes comprise a direct-access local memory unit (38), and a storage server (46) for managing access to this unit on the basis of a queue, - application nodes, each comprising: * an application environment with a representation of files that are accessible in the form of addresses of blocks designating a physical address on a local memory unit (33), and * a storage client (44) capable of interacting with a storage server (46), on the basis of an access request designating a block address. A storage server (46) comprises a scheduler capable of executing the access requests contained in its queue (64) in a determined order. This order is determined as a function of a set of rules forming performance criteria, and involving one or more state parameters of the queue and/or of the storing node on which it resides.
    • 基于计算机的系统包括被称为在网络中互连的节点的几个基于计算机的设备， - 存储节点包括直接访问本地存储器单元（38）和存储服务器（46），用于基于 - 应用节点，每个包括：*具有可以以指定本地存储器单元（33）上的物理地址的块的地址形式访问的文件的表示的应用环境，以及*存储客户端（44） 能够基于指定块地址的访问请求与存储服务器（46）进行交互。 存储服务器（46）包括能够以确定的顺序执行包含在其队列（64）中的访问请求的调度器。 该顺序被确定为形成性能标准的一组规则的函数，并且涉及其驻留在其上的队列和/或存储节点的一个或多个状态参数。
