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 translation: 公开了一种存储区域网络（SAN）的存储系统结构。 存储系统提供强烈一致的分布式存储通信协议语义，如SCSI目标语义。 该系统包括通过将构成单个分布式逻辑单元的每个逻辑子单元相关联来向主机系统提供包括一个或多个逻辑子单元作为单个逻辑单元的单个分布式逻辑单元的机制 具有对应于单个分布式逻辑单元的单个主机可见标识符。 该系统还包括为每个逻辑子单元维护一致的上下文信息的机制，使得逻辑子单元作为与单个分布式逻辑单元的单独实体不能作为主机系统可见。
