    摘要： Recovery requests are scheduled and prioritized according to priority valuations of the minimum time to next failure relative to the minimum time to next recovery for corresponding storage data sets. The prioritization can be performed by an upper layer recovery scheduler that dispatches requests to different storage units and/or by lower layers and individual storage unit schedulers. Prioritizations can be reflected in tagging on recovery requests, as determined by a first entity, and/or determined dynamically at the point of dispatch and processing.

    摘要： A volume system that presents a volume having an extent of logical addresses to a file system. A volume exposure system exposes the volume to the file system in a manner that the volume has multiple tiers, each offering storage of different traits. This is performed using multiple heterogenic underlying storage systems, each having different storage system-specific traits. Each underlying storage system may be hardware, software, or a combination thereof that permits each storage system to expose storage having the particular storage system-specific traits to the file system. The volume system supports each tier by mapping logical addresses of the tier to portions of underling storage systems that are consistent with the tier traits.

    摘要： Embodiments are directed to dynamically changing partitions size for a partition in a storage device and to transferring storage space between partitions in a storage device. A computer system identifies portions of free space on a storage device, where the storage device has at least one partition whose offset and length are stored in a partition table. The computer system determines where the identified free space is located relative to other storage locations on the storage device. The computer system further determines that the partition is to be dynamically resized to a new size which is specified by one or more offset and length values, and based on where the identified free space is located, dynamically transforms the partition into a logical partition, and resizes the logical partition, the logical partition's offset and length values being updated in the partition table to include the new specified offset and length values.

    摘要： Embodiments are directed to modifying storage capacity within a data store and to modifying resiliency for a data store. In one scenario, a computer system receives a request to move data. The computer system may determine that data is to be moved from an allocation on one data store to a new allocation on another data store. The computer system may create a new allocation on the other data store, where the new allocation is configured to receive data from the first data store. The computer system then moves the data to the new allocation on the second data store as data I/O requests are received at the first data store. Data store access requests are synchronized with the data movement by directing the data store access requests to the first data store, to the second data store or to both data stores depending on the type of access request.

    摘要： Physical (or prior virtual) machine volumes can be converted to virtual machines at a virtual machine host while the physical machines are running. In one implementation, a volume shadow copy service can be used to create an application (and/or file system)-consistent snapshot of one or more physical machine volumes while the one or more volumes are running. The snapshot data can then be transferred to a mounted virtual hard disk file (dynamic or fixed) at a virtual machine host. Operational information (e.g., boot record, system registry, drivers, devices, configuration preferences, etc.) associated with the virtual hard disk file and the operating system(s) within the virtual machine can then be modified as appropriate to ensure that the corresponding virtual machine is bootable and functional at the virtual machine host. The virtual hard disk file can then be un-mounted, and used as a new virtual machine.
