摘要： In one embodiment of the invention, a utility may be installed (e.g., by a system administrator) on a storage system. The utility may read content units on the storage system that are stored in one data format, and convert the content units to a second data format. In one embodiment, in response to a read request for a content unit, a data format in which to return the content unit may be selected and the content unit may be returned in that data format. In another embodiment, mapping information may be created that specifies in which data format a content unit should be returned in response to a request for the content unit. The mapping information may be stored either on the storage system that stores the content unit, the computer requesting access to the content unit, or any other computer or device in the computer system.

摘要： A storage system provides highly flexible data layouts that can be tailored to various different applications and use cases. The system dynamically balances performance with block sharing, based on service level objectives (SLOs). The system defines several types of data containers, including “regions”, “logical extents” and “slabs”. Each region includes one or more logical extents. Allocated to each logical extent is at least part of one or more slabs allocated to the region that includes the extent. Each slab is a set of blocks of storage from one or more physical storage devices. The slabs can be defined from a heterogeneous pool of physical storage. The system also maintains multiple “volumes” above the region layer. Each volume includes one or more logical extents from one or more regions. Layouts of the extents within the regions are not visible to any of the volumes.

摘要： A system and method for allocating data objects across multiple physical storage devices in a mass storage subsystem first determines a set of physical properties associated with the physical storage devices. The system assigns portions of the mass storage subsystem to a first division or a second division based on the physical properties, such that read operations directed to logically related data stored in the first division can be executed more efficiently than read operations directed to data stored in the second division. During operation, the system stores data objects with a low SLR in the second division, which may be allocated according to any well-known file system. If a write request is for a new data object with a high SLR, the system stores the new data object in a set of neighboring primary data chunks in the first division. For subsequent write requests that modify a stored data object, the system stores the modified data in a spillover data chunk located in proximity to the primary data chunk.

摘要： A storage system provides highly flexible data layouts that can be tailored based on reliability considerations. The system allocates reliability values to logical containers at an upper logical level of the system based, for example, on objectives established by reliability SLOs. Based on the reliability value, the system identifies a specific parity group from a lower physical storage level of the system for storing data corresponding to the logical container. After selecting a parity group, the system allocates the data to physical storage blocks within the parity group. In embodiments, the system attaches the reliability value information to the parity group and the physical storage units storing the data. In this manner, the underlying physical layer has a semantic understanding of reliability considerations related to the data stored at the logical level. Based on this semantic understanding, the system has the capability to prioritize data operations on the physical storage units according to the reliability values attached to the parity groups.
