Abstract: Systems and methods are described herein for routing data by transferring a physical storage device for at least part of a route between source and destination locations. In one example, a computing resource service provider, may receive a request to transfer data from a customer center to a data center. The service provider may determine a route, which includes one or more of a physical path or a network path, for the data loaded onto a physical storage device to reach the data center from the customer center. Determining the route may include associating respective cost values to individual physical and network paths between physical stations between the customer and end data centers, and selecting one or more of the paths to reduce a total cost of the route. Route information may then be associated with the physical storage device based on the route.

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: One or more configuration parameters for an object gateway instance are received at an interface to a provider network, the parameters including an identifier of a first object store of the provider network for which to cache objects in a first object cache of the object gateway instance and an indication of a data transfer mode that controls when objects written to the first object cache are written to the first object store. The one or more configuration parameters are stored in a data store of the provider network and sent to the object gateway instance. A read request that includes the identifier of the first object store and a first object identifier is received from the object gateway instance, and a first object associated with the first object identifier and stored in the first object store is sent to the object gateway instance.

Abstract: A data storage system includes a rack, multiple head nodes, multiple data storage sleds, and at least two networking devices. The at least two network devices are configured to implement at least two redundant networks within the data storage system. Also, each of the head nodes is assigned at least two network addresses for communication with the data storage sleds of the data storage system via the at least two networking devices. The data storage sleds each include multiple mass storage devices and a sled controller that is configured to couple with the at least two network switches. IO In some embodiments, the data storage system further includes redundant power systems within a rack in which the head nodes, the data storage sleds, and the at least two networking devices are mounted.

Abstract: A data storage system includes multiple head nodes and data storage sleds. A control plane of the data storage system designates, for a volume partition, one of the head nodes to function as a primary head node storing a primary replica of the volume partition and designates two or more other head nodes to function as reserve head nodes storing reserve replicas of the volume partition. Additionally, the primary head node causes volume data for the volume partition to be erasure encoded and stored on multiple mass storage devices in different ones of the data storage sleds.

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: A failure of a storage device used to provide a mirrored storage volume can be managed without a full re-mirroring of the volume. The volume can be provided using a set of similar storage devices on each of a master server and a slave server, and a technique such as data striping can be used to store the data for the volume across the various devices. When a storage device becomes unavailable, the data from the corresponding storage device on the other mirrored server can be written to the remaining storage devices on the server experiencing the device failure. The data interface can be virtualized such that the user can continue to send input and output (I/O) requests using the same address information. A translation layer can map the virtualized addresses to the physical addresses where the data is stored.

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 to a set of the mass storage devices of the data storage system. 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. In some embodiments an index includes a current version reference for a volume or portion of a volume and one or more point-in-time snapshot references.

Abstract: A block-based storage system hosts logical volumes that are implemented via multiple replicas of volume data stored on multiple resource hosts in different failure domains. Also, the block-based storage service allows multiple client computing devices to attach to a same given logical volume at the same time. A membership group authority authorizes sequence numbers for a given logical volume and an associated membership group. The members of the membership group ensure that the members are in agreement on the latest sequence number for the given logical volume before responding to read or write requests directed to the given logical volume.
