Abstract: A method of distributed file deletion, performed by a storage system, is provided. The method includes receiving, at the storage system, a request to delete a directory and contents of the directory and adding the directory to a first set, listed in a memory in the storage system. The method includes operating on the first set, by examining each directory in the first set to identify subdirectories, adding each identified subdirectory to the first set as a directory, and adding each examined directory to a second set listed in the memory. The method includes deleting in a distributed manner across the storage system without concern for order, contents of directories, and the directories, listed in the second set.

Abstract: A list of a available zones across respective SSD storage portions of a plurality of zoned storage devices of a storage system is maintained. Data is received from multiple sources, wherein the data is associated with processing a dataset, the dataset including multiple volumes and associated metadata. Shards of the data are determined such that each shard is capable of being written in parallel with the remaining shards. The shards are mapped to a subset of the available zones, respectively. The shards are written to the subset of the available zones in parallel.

Abstract: A storage system performs data replication with a recovery point objective (RPO). The storage system replicates data at intervals through data transfers over a network. The storage system determines bandwidth of the network. The storage system determines the intervals for replicating the data, based on size of data transfers, network bandwidth, and the recovery point objective.

Abstract: Symmetric storage using a cloud-based storage system, including: receiving, at a cloud-based storage system among storage systems synchronously replicating a dataset, an I/O operation directed to the dataset; determining, in dependence upon the I/O operation, a metadata update describing a mapping of segments of content to an address within a storage object, wherein the storage object includes the dataset; and synchronizing metadata on another storage system of the storage systems by sending the metadata update from the cloud-based storage system to the other storage system to update a metadata representation on the second storage system in accordance with the metadata update.

Abstract: Creating a replica of a storage system, including: receiving, by a first storage system from a computing device, data to be stored on the first storage system; reducing, by the first storage system, the data using one or more data reduction techniques; sending, from the first storage system to the second storage system, the reduced data, wherein the reduced data is encrypted; and sending, from the second storage system to a third storage system, the reduced data, wherein the reduced data is encrypted.

Abstract: A storage cluster includes a plurality of storage nodes. Each of the plurality of storage nodes includes nonvolatile solid-state memory and each of the plurality of storage nodes is configured to cooperate with others of the plurality of storage nodes having differing storage capacities in applying erasure coding. The plurality of storage nodes are configured to distribute the user data and metadata throughout the plurality of storage nodes.

Abstract: Recovery for storage systems synchronously replicating a dataset, including: receiving, by at least one storage system among the plurality of storage systems synchronously replicating the dataset, a request to modify the dataset; generating recovery information indicating whether the request to modify the dataset has been applied on all storage systems in the plurality of storage systems synchronously replicating the dataset; and responsive to a system fault, applying a recovery action in dependence upon the recovery information indicating whether the request to modify the dataset has been applied on all storage systems in the plurality of storage systems synchronously replicating the dataset.

Abstract: Cloning a tracking copy of replica data, including receiving, at a target data repository from a source data repository, metadata describing one or more updates to a dataset stored within the source data repository; generating, based on the metadata describing the one or more updates to the dataset, a tracking copy of replica data on the target data repository; and generating, based on the tracking copy, a cloned image of the dataset that is modifiable without modifying the tracking copy of the replica data.
