Abstract: The present disclosure generally relates to creating virtualized block storage devices whose data is replicated across isolated computing systems to lower risk of data loss even in wide-scale events, such as natural disasters. The virtualized device can include at least two volumes, each of which is implemented in a distinct computing system. In the case of a failed volume, a new volume can be created and populated with data from the surviving volume. During population, new writes can continue to be replicated to the new volume. The population process can write data from the surviving volume to the new volume “under” new writes, such that the population process does not overwrite data included in the new writes.

Abstract: Commitments against various resources can be dynamically adjusted for customers in a shared-resource environment. A customer can provision a data volume with a committed rate of Input/Output Operations Per Second (IOPS) and pay only for that commitment (plus any overage), for example, as well as the amount of storage requested. The customer can subsequently adjust the committed rate of IOPS by submitting an appropriate request, or the rate can be adjusted automatically based on any of a number of criteria. Data volumes for the customer can be migrated, split, or combined in order to provide the adjusted rate. The interaction of the customer with the data volume does not need to change, independent of adjustments in rate or changes in the data volume, other than the rate at which requests are processed.

Abstract: Generally described, one or more aspects of the present application correspond to techniques for creating multiple encrypted block store volumes of data from an unencrypted source. These encryption techniques can use a transform fleet as an intermediary use between the unencrypted source and the encrypted volumes. The transform fleet can obtain data of the volume from one or both of two sources—an object storage “snapshot” a block storage “source volume”—and can then apply the appropriate encryption key for performing the encryption of a particular volume.

Abstract: Generally described, one or more aspects of the present application correspond to techniques for creating encrypted block store volumes of data from unencrypted object storage snapshots of the volumes. These encryption techniques use a special pool of servers for performing the encryption. These encryption servers are not accessible to users, and they perform encryption and pass encrypted volumes to other block store servers for user access. The encryption context for the volumes can be persisted on the encryption severs for as long as needed for encryption and not shared with the user-facing servers in order to prevent user access to encryption context.

Abstract: A data storage system includes multiple head nodes and data storage sleds. The data storage sleds include multiple mass storage devices and a sled controller. Respective ones of the head nodes are configured to obtain credentials for accessing particular portions of the mass storage devices of the data storage sleds. A sled controller of a data storage sled determines whether a head node attempting to perform a write on a mass storage device of a data storage sled that includes the sled controller is presenting with the write request a valid credential for accessing the mass storage devices of the data storage sled. If the credentials are valid, the sled controller causes the write to be performed and if the credentials are invalid, the sled controller returns a message to the head node indicating that it has been fenced off from the mass storage device.

Abstract: A user can set or modify operational parameters of a data volume stored on a network-accessible storage device in a data center. For example, the user may be provided access to a data volume and may request a modification to the operational parameters of the data volume. Instead of modifying the existing data volume, the data center can provision a new data volume and migrate data stored on the existing data volume to the new data volume. While the data migration takes place, the existing data volume may block input/output (I/O) requests and the new data volume may handle such requests instead. Once the data migration is complete, the data center may deallocate the data blocks of the existing data volume such that the data blocks can be reused by other data volumes.

Abstract: A data storage system includes a head node and mass storage devices. The head node is configured to flush data stored in a storage of the head node, based at least in part on one or more triggers being met, from the storage of the head node to a set of the mass storage devices of the data storage system. The flushed data is written to a segment of free storage space across the set of the mass storage devices allocated for the given data flush operation. In some embodiments, a head node may flush both current version data and point-in-time version data to the set of mass storage devices. Also, the data storage system maintains an index that indicates storage locations of data for particular portions of a volume before and after the data is flushed to the set of mass storage devices.

Abstract: Master-slave pairs can be used to provide data redundancy in an electronic data environment. A master peer can include a B-tree with references to the corresponding data. When provisioning a slave, the master can send a point-in-time copy of the B-tree to the slave, which can allocate the necessary space on local storage and update the references of the B-tree to point to the local storage for the slave. If the master and slave become disconnected, one of the peers can function as a solo master until the peers are again connected, at which point the old peer can be brought current or a new slave provisioned. A log peer can also be provisioned by a solo master, which can store data for operations received during the disconnect for use in catching up a slave peer, which could be the old slave, the log peer, or a new peer.

Abstract: A snapshot object or other type of object may be stored in a first storage system and may be accelerated in another storage system, wherein an accelerated snapshot or other type of object can be used to populate volumes in the other storage system with data more rapidly than a non-accelerated snapshot or other type of object. The accelerated snapshot or other object may be implemented using an intermediate volume implemented in the other storage system that is populated with data from the snapshot object or the other object stored in the first storage system.
