摘要： A data storage system is configured to provide a graphical display that shows the user a logical schematic of interconnected disk enclosures of a data storage system along with any erroneous connections among the disk enclosures. The graphical display, therefore, allows the user to visually identify the disk drive enclosures in the data storage system and any erroneous connections formed between the disk enclosures. Additionally, the data storage system is configured to monitor the connections among the disk enclosures and provide updated graphical displays to the user showing any changes to the connections among the disk enclosures. In the event that a connection between two disk enclosures malfunctions or becomes inoperable, the graphical display allows the user to easily identify the location of connection error.

摘要： A technique involves managing state changes of a data storage system in a computerized device configured to obtain object trees representing state information of the data storage system. The technique includes receiving a first object tree which represents the data storage system at a first time, and receiving a second object tree which represents the data storage system at a second time. The second time is after the first time. The technique further includes generating a set of tree comparison results from a comparison between the first object tree representing the data storage system at the first time and the second object tree representing the data storage system at the second time. The set of tree comparison results indicate whether state changes have occurred in the data storage system.

摘要： Described are techniques for accessing data. The data is stored in a tree data structure at a first location. A hash value is determined in accordance with a portion of said data. An entry is created in a hash table in accordance with said hash value for said data. The entry includes a reference to said data at said first location, wherein said data is accessible at said first location using a first retrieval technique for said tree data structure and using a second retrieval technique for said hash table.

摘要： A method is used in determining alternate paths in faulted systems. It is detected that a first processor has a problem accessing a target. The first processor has a first path to the target. An alternate path to the target is determined by identifying that a second processor has better access to the target than the first processor. The second processor has a second path to the target. Responsibility for I/O communication with the target is transferred from the first processor to the second processor. Responsibility for I/O communication with the target is transferred back to the first processor upon resolution of the problem.

摘要： A technique enables managing distribution of well-defined objects. The technique involves maintaining a database of well-defined objects and a registry of identifiers. The technique further involves receiving an object request from a client device. The object request includes a particular identifier. The technique further involves providing (i) all of the well-defined objects from the database in response to the well-defined object request when the particular identifier of the well-defined object request is at least as recent as the most recent identifier in the registry, and alternatively (ii) less than all of the well-defined objects from the database in response to the well-defined object request when the particular identifier of the well-defined object request is not as recent as the most recent identifier in the registry. Accordingly, an older client device can be prohibited from receiving a newer well-defined object thereby preventing the older client device from attempting to construct the newer object and inadvertently failing.
摘要翻译：一种技术可以管理明确定义的对象的分布。该技术涉及维护明确定义的对象和标识符注册表的数据库。该技术还涉及从客户端设备接收对象请求。对象请求包括特定的标识符。该技术进一步涉及当定义明确的对象请求的特定标识符至少与最近的标识符最近一致时，提供（i）响应于明确定义的对象请求，从数据库中提供（i）所有明确定义的对象注册表，以及（ii）当定义明确的对象请求的特定标识符不如最近的标识符中最近的标识符时，响应于定义良好的对象请求，（ii）少于来自数据库的所有明确定义的对象注册表。因此，可以禁止较旧的客户端设备接收较新的明确定义的对象，从而防止较旧的客户端设备尝试构建较新的对象并且无意中发生故障。
