摘要： A storage server resizes an array of mass storage devices and distributes data blocks stored in the array of mass storage devices evenly in a declustered organization across the resized array of mass storage devices. Resizing the array of mass storage devices may include adding a new mass storage device to the array or removing a mass storage device from the array. During resizing a data block is moved from one mass storage device to another mass storage device to minimize the imbalance of parity groups shared by the new mass storage devices in the array, as well as minimize the number of data blocks to be moved to uniformly balance the load across the new mass storage device.

摘要： A data storage system can automatically improve the layout of data blocks on a mass storage subsystem by collecting optimization information during both read and write activities, then processing the optimization information to limit the impact of optimization activities on the system's response to client requests. Processing read-path optimization information and write-path optimization information through shared rate-limiting logic simplifies system administration and promotes phased implementation, which can reduce the difficulty of developing a self-optimizing storage server.

摘要： A method of exposing the functionality of an application in a command interface includes generating a command line interpreter (“CLI”) from a component of an application. The application's components are used to automatically generate the CLI to interpret commands to access the functionality of the application. The generated CLI parses, maps, and dispatches the commands and any associated arguments in accordance with the application's components. Application metadata is used to modify the generated CLI to customize the exposure of the functionality of the application in the command interface.

摘要： A mass data storage system including a data storage device comprising block groups each comprising a plurality of data blocks determines when one of the block groups is faulty and the data storage device continues to operate as a partially failed data storage device with respect to the remaining block groups which are not faulty. A striped parity data storage device array comprises data storage devices capable of operating as partially failed data storage devices allows copying of data from the block groups not associated with determined to be faulty of a partially failed data storage device to a spare data storage device which reduces the amount of data that must be rebuilt in the rebuild process, thereby reducing the amount of time the array spends in degraded mode exposed to a total loss of data caused by a subsequent data storage device failure.

摘要： An image-based backup backs up one or more snapshots of a volume without duplicating common data blocks. A backup engine receives a request to generate a backup image of a volume. In response to the request, the backup engine generates the backup image including data blocks and metadata describing attributes of the data blocks. The data blocks and the metadata arranged in the backup image in a same order as they were retrieved without imposing any additional ordering constraints on the data blocks and the metadata.

摘要： To promote an image, an identification of at least one of an symbol name and an existing symbol value associated with the symbol name is received. An identification of a new symbol value is also received. It is then determined that a binary file that is a component of an unpromoted image is to be modified, wherein the image has previously been compiled and linked. The binary file is read to find occurrences of at least one of the symbol name or the existing symbol value in the binary file. The existing symbol value is replaced with the new symbol value to promote the image. The image is promoted without recompiling or relinking the binary file.

摘要： A method of improving storage security in a cloud environment includes interfacing a secure microcontroller with a storage controller associated with a client device in the cloud environment to authenticate a platform associated with the storage controller and registering the storage controller with an authentication server configured to be set up in the cloud environment. The method also includes authenticating the storage controller based on a communication protocol between the client device, the authentication server and the storage controller, and obtaining, at the client device, a signature data of the storage controller following the authentication thereof. The signature data is configured to be stored in the secure microcontroller interfaced with the storage controller.

摘要： Image-based data restoration restores an entire image of a volume or selective files. A restore engine receives a request to restore data from a backup image that includes a plurality of data blocks and metadata describing attributes of the data blocks. In response to the request, the restore engine determines a restore mode. If it is determined to be a logical restore mode, the restore engine restores a file by retrieving the metadata associated with the file and the data blocks that are pointed to by the metadata. If it is determined to be an image restore mode, the restore engine restores an entire image of the volume by using the data blocks in the backup image without using the metadata.
