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: An illustrative embodiment disclosed herein is an apparatus including a processor having programmed instructions to determine a frequency rate for tracking changed data of a virtual machine (VM), track the changed data at the determined frequency rate, receive a request to generate a recovery point associated with a specified time, and, responsive to receiving the request to generate the recovery point associated with the specified time, generate the recovery point.

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.

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.
