Abstract: Techniques for distributing data in a distributed data storage system using a hierarchy rule that is generated based on a spreading policy and a set of tolerable failures specified by a user in absence of system deployment information are disclosed. The system includes a controller node which receives a request including a spreading policy and a protection level for spreading a first data object. The controller node determines a hierarchy rule corresponding to the spreading policy based on the protection level. The controller node distributes the first data object in the system using the hierarchy rule and the spreading policy. The controller node receives a reconfiguration of system deployment. The controller node distributes a second data object in the system based on providing protection of the protection level to the second data object without affecting protection of the same protection level applied to the first data object.

Abstract: Storage access requests are received from one or more applications. Multiple servers update multiple virtual disks as directed by the storage access requests. The virtual disks store data that is write order dependent across the virtual disks. Logs are associated with the virtual disks. Information associated with each storage access request is stored in one of the logs. A cycle of log switching is performed. A write order consistent tracking coordinator coordinates the log switching with agents at the servers to maintain request ordering. Replication coordinators coordinate the application of the switched-out log files from primary storage to replica storage, creating a write-order consistent point on the replica side matching the primary side, and providing for failure resiliency regarding transfer of the logs. The replication logs may be received individually on the replica side from the servers on the primary side to enable highly scalable parallel/simultaneous transfers of the logs.

Abstract: Techniques and systems are disclosed for implementing non-blocking writes to eliminate the fetch-before-write requirement by creating an in-memory patch for the updated page and unblocking the calling process. Non-blocking writes eliminate such blocking by buffering the written data elsewhere in memory and unblocking the writing process immediately. Subsequent reads to the updated page locations are also made non-blocking and, in some cases, can be eliminated when the read request can be serviced from in-memory patches. Implementation scenarios can include an operating system (OS) enhancement, revision to an existing OS component (e.g., the OS kernel), special OS component, or enhancement to the software or firmware of the controller software or microcontroller of a storage device or array of storage devices.

Abstract: A technique uses file system indirection to manage solid state devices (SSDs). Based on relocation of data on the SSDs from a first SSD storage block to a second SSD storage block, a flash translation layer (FTL) driver may update a per-volume indirection file to reference the second SSD storage block and no longer reference the first SSD storage block. Based on a mismatch between the per-volume indirection file and a buffer tree, the buffer tree is updated to reference the second SSD storage block. Alternatively, the FTL driver may create and insert an entry into a mapping table, wherein the entry may reference the first SSD storage block and also reference the second SSD storage block. The buffer tree may then be updated to reference the second SSD storage block based on the new entry, and the new entry may then be deleted after the buffer tree is updated.

Abstract: Deployment and servicing tasks associated with multi-tier, distributed applications, application environments and data centers are automated so that a person does not have to manually perform these tasks. All of the information describing and defining the distributed service is modeled and stored in a re-useable service template that can be used to drive an automated system to programmatically deploy and manage the service over time.

A sequential write request is processed without claiming any cache space, when data for the write request is not to be accessed within a certain duration.

Abstract: A cloud computing system can be used to transparently reduce the storage space of an application on a client device. An application can be installed with a minimal set of application resource files. The remaining application resource files can be replaced with application resource file placeholders, which can have the appearance of application resource files but are in fact empty files. When an application requests an application resource file, an application resource file retrieval process installed on the client device can detect the difference between an application resource file and an application resource file placeholder. The application resource file retrieval process can trigger a fault in response to detecting an application resource file placeholder, which causes the client device to obtain the requested application resource file from a remote storage location, such as cloud-based storage. Additionally, installed application resource files can be replaced with application resource file placeholders.
