摘要： An example method for backend replication of data in a distributed storage system comprises receiving, by a container storage management system, a request to generate a mirror site of a data site comprising a backend storage system providing storage resources associated with a plurality of storage volumes of a container system; generating, by the container storage management system and based on the receiving the request to generate the mirror site, architecture data describing an organization of the plurality of storage volumes on the data site; and directing, by the container storage management system, the backend storage system to transfer, based on the architecture data, data to the mirror site via a pathway outside the container storage management system.

摘要： Creating a modifiable cloned image of a dataset, including: generating, based on a dataset stored within a source data repository, a tracking copy of replica data on a target data repository; generating, after receiving an indication to begin accepting modifications to the tracking copy of the replica data, a cloned image of the dataset that is modifiable without modifying the tracking copy of the replica data; and responsive to a storage operation directed to the target data repository, modifying the cloned image of the dataset without modifying the tracking copy of the replica data.

摘要： A method for proactively rebuilding user data in a plurality of storage nodes of a storage cluster in a single chassis is provided. The method includes distributing user data and metadata throughout the plurality of storage nodes such that the plurality of storage nodes can read the user data, using erasure coding, despite loss of two of the plurality of storage nodes. The method includes determining to rebuild the user data for one of the plurality of storage nodes in the absences of an error condition. The method includes rebuilding the user data for the one of the plurality of storage nodes. A plurality of storage nodes within a single chassis that can proactively rebuild the user data stored within the storage nodes is also provided.

摘要： A storage system has zones in solid-state storage memory, with power loss protection. The system identifies portions of data for processes that utilize power loss protection. The system determines to activate or deactivate power loss protection for the portions of data for the processes. The system tracks activation and deactivation of power loss protection in zones in the solid-state storage memory, in accordance with the portions of data having power loss protection activated or deactivated.

摘要： Volume migration among a set of storage systems synchronously replicating a dataset for a volume, where volume migration includes: initiating a transfer of the volume in dependence upon determining that a performance metric for accessing the volume stored on a first storage system would improve if transferred to a second storage system; and during the transfer of the volume: determining status information for the transfer; intercepting an I/O operation directed to the volume; and directing, in dependence upon the status information, the I/O operation to either the first storage system or the second storage system.

摘要： A method includes writing sets of encoded data slices to storage units of a storage network in accordance with error encoding parameters, where for a set of encoded data slices, the error encoding parameters include an error coding number and a decode threshold number, the error coding number indicates a number of encoded data slices that results when a data segment is encoded using an error encoding function and the decode threshold number indicates a minimum number needed to recover the data segment. The method further includes monitoring processing of the writing the sets of encoded data slices to produce write processing performance information. When the write processing performance information compares unfavorably to a desired write performance range, the method further includes adjusting at least one of the error coding number and the decode threshold number to produce adjusted error encoding parameters for writing subsequent encoded data slices.

摘要： Preparing data for deduplication including: generating, by a storage system for a compressed data block, a padded compressed data block by padding the compressed data block to conform to a fixed block size, wherein the fixed block size is greater than a size of the compressed data block; storing, in the storage system, the padded compressed data block beginning at a block boundary of a storage device in the storage system; and performing block-based deduplication on the storage system, wherein the block-based deduplication determines whether the padded compressed data block matches one or more other padded compressed data blocks stored in the storage system.
