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: Consistent distributed storage communication protocol semantics, such as SCSI target semantics, in a clustered storage system are disclosed. 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 a mechanism 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: 在集群存储系统中公开了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。 该系统还包括一种用于为每个逻辑子单元维护一致的上下文信息的机制，使得逻辑子单元对于作为与单个分布式逻辑单元的分离实体不是主机系统可见的。

Abstract: Method and system for detecting migration of a virtual machine are provided. The method detects that a first identifier for identifying a virtual machine and a second identifier identifying a source computing system hosting the virtual machine that accesses a storage space via a logical object have changed, when the virtual machine is migrated from the source computing system to a destination computing system. Thereafter, a storage device at the destination computing system is initialized to operate as a caching device for the migrated virtual machine.

Abstract: A storage platform computing apparatus obtains a lifecycle management policy and configuration information for a cloud repository identified in the lifecycle management policy. The configuration information includes at least one access parameter for the cloud repository. The lifecycle management policy is applied to determine when an object is required to be replicated to the cloud repository in response to a received write request. A request to store the object in the cloud repository is generated, when the object is determined to be required to be stored in the cloud repository, wherein the request includes the access parameter. The request is sent to the cloud repository using a representational state transfer (REST) interface associated with the cloud repository.
