Abstract: A storage area network (SAN)-attached storage system architecture is disclosed. The storage system provides strongly consistent distributed storage communication protocol semantics, such as SCSI target semantics. The system includes a mechanism for presenting a single distributed logical unit, comprising one or more logical sub-units, as a single logical unit of storage to a host system by associating each of the logical sub-units that make up the single distributed logical unit with a single host visible identifier that corresponds to the single distributed logical unit. The system further includes mechanisms to maintain consistent context information for each of the logical sub-units such that the logical sub-units are not visible to a host system as separate entities from the single distributed logical unit.

Abstract: A system and method of managing event tracking includes a tracking registry. The tracking registry includes a memory for storing tracking entries, a tracking entry hierarchy, and a registry interface configured to receive requests from a plurality of modules. The tracking registry opens a tracking entry based on a registry request received from a first module of the plurality of modules, and being associated with a first operation being handled by the first module and including a parent identifier of a parent tracking entry of the tracking entry, updates the tracking entry hierarchy based on the parent identifier, stores the first tracking entry in the memory, and closes the tracking entry based on an entry closing request received from a second module of the plurality of modules and being associated with completion of a second operation being handled by the second module. The second operation performs processing associated with completion of the first operation.

Abstract translation: 管理事件跟踪的系统和方法包括跟踪注册表。 跟踪注册表包括用于存储跟踪条目的存储器，跟踪条目层次结构以及被配置为从多个模块接收请求的注册表界面。 跟踪注册表基于从多个模块中的第一模块接收的注册表请求打开跟踪条目，并且与由第一模块处理的第一操作相关联，并且包括跟踪条目的父跟踪条目的父标识符 基于所述父标识符来更新所述跟踪条目层级，将所述第一跟踪条目存储在所述存储器中，并且基于从所述多个模块中的第二模块接收到的条目关闭请求来关闭所述跟踪条目，并且与所述第二跟踪条目的完成相关联 操作由第二模块处理。 第二操作执行与完成第一操作相关联的处理。
