Abstract: A system and method for signature based data container recognition is provided. When a new data container, such as a lun, is created, a security appliance generates a signature of the data container, by, e.g., examining the contents of one or more data blocks of the data container. The generated signature is then associated with the appropriate encryption key for the data container and is stored either within a configuration database of the security appliance or on a key management system operating within a security appliance environment. To identify the encryption key associated with a data container, the security appliance generates a signature of the data container and compares the generated signature with the stored signatures. Should there be a matching signature, the security appliance utilizes the encryption key associated with the matching signature to process data access requests to/from the data container.

Abstract translation: 提供了一种基于签名的数据容器识别的系统和方法。 当创建诸如lun的新数据容器时，安全设备通过例如检查数据容器的一个或多个数据块的内容来生成数据容器的签名。 生成的签名然后与数据容器的适当的加密密钥相关联，并存储在安全设备的配置数据库内或在安全设备环境中运行的密钥管理系统上。 为了识别与数据容器相关联的加密密钥，安全设备生成数据容器的签名，并将生成的签名与存储的签名进行比较。 如果存在匹配的签名，则安全设备利用与匹配签名相关联的加密密钥来处理对数据容器的数据访问请求。

Abstract: An apparatus and a method to manage data using data sets are presented. In one aspect, the apparatus includes a conformance checker and a conformance engine to make data sets conform to data management policies. The conformance checker may be operable to compare a state of a data set against a data management policy associated with the data set. The conformance engine may then make the data set conform to the data management policy if the conformance checker determines that the data set currently violates the data management policy. In another aspect, the method includes allowing an administrator of a data storage system to define a data set having a plurality of storage objects and to associate the data set with a data management policy. The method may further include using a storage manager to manage the data set as a single unit according to the data management policy.

Abstract: A system and method for referent-controlled location resolution of resources in a federated distributed system. When a client requests access to a data container from a storage system that is a member of a first federation, the storage system determines whether the requested data of the data container is locally stored. If the requested data is not locally stored, i.e., a junction exists in the local volume referencing a second volume serviced by a second federation member, the first federation member identifies the appropriate context identifier (CID) associated with the junction. The junction illustratively contains a remote volume locator and an object identifier. The CID identifies a VLDB that contains location information related to the desired data container. The first federation member resolves the CID to an appropriate VLDB service and sends a lookup request to the identified VLDB associated with the second federation member. The lookup request is processed by the VLDB and the VLDB responds with the one or more locations of the requested data container within the second federation member. The first federation member then responds to the client's original access request with a message indicating the current location(s) of the requested data container. The client then requests access to the desired data by redirecting the data access request to the identified second federation member.

Abstract translation: 一种联合分布式系统中资源控制位置解析的系统和方法。 当客户端请求从作为第一联盟成员的存储系统访问数据容器时，存储系统确定数据容器的请求数据是否被本地存储。 如果所请求的数据不是本地存储的，即，引用由第二联合成员服务的第二卷的本地卷中存在联结，则第一联合成员​​标识与该连接相关联的适当上下文标识符（CID）。 接口说明性地包含远程卷定位符和对象标识符。 CID标识包含与所需数据容器相关的位置信息的VLDB。 第一联合成员​​将CID解析为适当的VLDB服务，并将查找请求发送到与第二联合成员相关联的所识别的VLDB。 查询请求由VLDB处理，VLDB用第二个联合成员内的所请求数据容器的一个或多个位置进行响应。 第一个投入组件然后用指示所请求的数据容器的当前位置的消息来响应客户端的原始访问请求。 然后，客户端通过将数据访问请求重定向到所识别的第二联合成员来请求对所需数据的访问。

Abstract: A field-upgradeable database that is separable from system software contains information about mass storage devices that may be present in a storage array. When an uninitialized device is detected in the array, the field-upgradeable database is consulted to discover which non-standard functions the device supports, and one of the non-standard functions is activated. Software and systems using the field-upgradeable database in a storage server configuration are also described and claimed.

Abstract: A filesystem can be converted to a different version by creating a new data structure according to a new format of the different version and transforming the data from the filesystem to the new data structure. Transforming the data can include changing the format of the data in the filesystem to be compatible with the new data structure format. The data may be incorporated into the new data structure by copying the data, or creating indirect reference mechanisms to point to the original data.

Abstract: A system and method provides continuous data protection using checkpoints in a write anywhere file system. During a consistency point of a write anywhere file system, freed blocks are identified and are appended to a delete log for retention. A consistency point log is updated with a new entry associated with the consistency point. If the file system needs to retrieve its state at a particular point in time, the stored blocks of the delete log may be recovered.

Abstract: A content addressable storage array element (CASAE) of a storage system is configured to eliminate duplicate data stored on its storage resources. The CASAE independently determines whether data associated with a write operation has already been written to a location on its storage resources. To that end, the CASAE performs a content addressable storage computation on each data block written to those resources in order to prevent storage of two or more blocks with the same data. If data of a block has been previously stored on the resources, the CASAE cooperates with a file system executing on the system to provide a reference (block pointer) to the same data block rather than duplicate the stored data. Otherwise, the CASAE stores the data block at a new location on the resources and provides a block pointer to that location.

Abstract translation: 存储系统的内容可寻址存储阵列元素（CASAE）被配置为消除存储在其存储资源上的重复数据。 CASAE独立地确定与写入操作相关联的数据是否已经被写入其存储资源上的位置。 为此，CASAE对写入这些资源的每个数据块执行内容可寻址存储计算，以防止具有相同数据的两个或更多块的存储。 如果块的数据已经预先存储在资源上，则CASAE与在系统上执行的文件系统协作以向同一数据块提供引用（块指针），而不是复制存储的数据。 否则，CASAE将数据块存储在资源的新位置，并提供到该位置的块指针。
