  • Patent number: 11836359
    Abstract: A block storage service can ensure volumes are placed in a same region as an attached virtual machine instance for performance and durability guarantees. A region can reference multiple things, but one example is that a volume is within a same spine as a virtual machine in order to meet performance guarantees. Each region can have a buffer of server computers held in reserve for volumes having a type where performance guarantees are required. If performance guarantees cannot be met, a rejection is transmitted to the customer. In another embodiment, the customer can provide a list in priority order of different volume types so that if a desired volume type cannot be placed, then alternative volume types can be used.

  • Publication number: 20230101673
    Abstract: An RF amplifier utilizes first and second main amplifiers in a balanced amplifier configuration with first and second auxiliary amplifiers connected in parallel across the first and second main amplifiers, respectively. The main and the auxiliary amplifiers are biased such that the third-order nonlinearity components in the combined output current are reduced. A common or independent bias control circuit(s) control(s) the DC operating bias of the auxiliary amplifiers and establishes DC operating points on curves representing third-order nonlinear components within the drain current having a positive slope (opposite to the corresponding slope of the main amplifiers). This results in reduction of overall third-order nonlinear components in combined currents at the output. In another embodiment, a phase shift of an input to one auxiliary amplifier is used to provide a peak in minimization at a frequency associated with the phase shift.

  • Patent number: 11503081
    Abstract: Systems and methods are described for implementing load-dependent encryption mechanism selection in an elastic computing system. The elastic computing system can include a set of host devices configured to implement block storage volumes on behalf of users. Users may desire that such volumes be encrypted prior to storing data. It may be generally preferable for encryption to occur on the same host devices that host the volume, to reduce latency and bandwidth usage needed to encrypt the data. However, encryption of data can utilize significant computational resources, which may not be available on host devices that also have sufficient storage resources to host the volume. The present disclosure describes systems and methods that can account for computational resource availability on host devices, selecting “in-place” encryption only when available resources exist on host devices, and otherwise implementing remote encryption of volume data.

  • Patent number: 11080092
    Abstract: Systems and methods are disclosed for handling requests to create multiple volumes with an expected usage correlation on a block storage service. Rather than handling each request to create a volume independently, embodiments described herein can handle the request in bulk, quickly determining whether the request as a whole can be handled at the system. In one embodiment, the service allows for oversubscription of use on hosts, as well as parallelization of placement decisions, by rejecting placement requests when a number of possible hosts for a volume within a requested set falls below a candidate set size, which is determined based on factors such as a number of requested volumes and an expected accuracy of state information for the service at a placement engine within a distributed set of engines.

  • Patent number: 11048554
    Abstract: Systems and methods are disclosed for handling requests to create multiple volumes with an expected usage correlation on a block storage service. Rather than handling each request to create a volume independently, embodiments described herein can handle the request in bulk. In one embodiment, the service allows for oversubscription of use on hosts, as well as parallelization of placement decisions, by distributing requests among a set of parallelized placement engines. Each engine can distribute its subset of volumes at least partly randomly among a candidate set of volumes, with the size of the candidate set selected based on a total number of volumes. This distribution mechanism can ensure distribution of volumes without requiring centralized placement of the volumes.

  • Patent number: 11023535
    Abstract: A new metadata field is described that can be used with requests to store a volume in a block storage service. The metadata field is a parameter included in the request and is a logical association identifier that associates the volume to be stored with other already-stored volumes. Using this logical association identifier, the block storage service can ensure that all volumes having the same identifier are sufficiently spread across server computers. The logical association identifier can be a workload identifier indicating that the volumes are all from a same relational database, application, etc. Target customers are defined as customers that request an action of a service within a cloud environment and the service then makes a request to the block storage service. In this case, the service is a customer of the block storage service and it can pass the target customer identifier as the logical association identifier.

  • Patent number: 10817325
    Abstract: Data volumes hosted for customers in a multi-tenant environment can be moved advantageously throughout the environment to improve performance and reduce cost. A data volume can serve I/O for a virtual machine instance, and it can be advantageous for the virtual machine and the data volume to be in the same network locality, or share at least some of the same network state and interconnection. Since there is limited capacity in a network locality, data volumes not attached to virtual machines can be moved to other locations in the environment. This can include moving data volumes to other local network topologies or snapshotting data volumes and writing the snapshots to another storage service. If the data volume is again needed for I/O, the data volume can moved, allocated, or reattached as necessary.

  • Patent number: 10725707
    Abstract: Data volumes for a customer can be placed on various storage tiers, including different hardware types or storage systems, that are determined to be appropriate for the anticipated usage of those data volumes. The actual usage can be monitored to determine one or more types of workload for the data volume, and a determination made as to whether all, or portions, of the data volume could obtain a significant performance improvement by being migrated to a different storage tier. In some instances the chunks or partitions of a volume can be concurrently distributed across multiple different storage tiers in order to satisfy various performance and/or cost criteria. Once workload information is available for a customer, that information can be used to determine the storage tiers for initial placement of subsequent data volumes.

  • Patent number: 10719235
    Abstract: Placement decisions can be made for data storage volumes based at least in part upon the requirements of the storage volumes and the capabilities of the types of hardware available to host those volumes. There may be multiple types of hardware capable of supporting a volume, and the placement can be biased to hardware capable of supporting fewer types of storage volumes in order to ensure sufficient capacity for the various types of storage volumes. A consistent level of performance can also be provided independent of the type of hardware utilized. Hardware can be selected to host a volume that is able to satisfy various volume requirements, and the operation can be adjusted to ensure that the volume requirements are satisfied over time.

  • Patent number: 10594620
    Abstract: A distributed system may implement analyzing bit vectors for resource placement. Bit vectors may be maintained or generated for currently hosted resources in a distributed system according to placement criteria so that individual bit values of a bit vector indicate whether a corresponding one of the placement criteria is satisfied for the current placement of the resource. A resource may be identified for migration and a possible placement determined for the resource. A bit vector may be generated for the possible placement and compared with the bit vector for the current placement of the resource to determine whether the possible placement improves the placement of the resource with respect to the placement criteria.

  • Patent number: 10564870
    Abstract: The allocation of resources, such as for data storage, can be performed based at least in part upon predicted values for utilization and growth, among other such values. Various features can be used to predict the initial utilization and growth rate for a data volume, and these predicted values can be used to determine where to place the volumes. The features can include, for example, customer usage history, volume type, volume purpose, type of attached virtual machine, and the like. The ability to predict actual usage can enable capacity to be allocated based on an as-needed basis instead of providing large blocks of allocated capacity that would go largely unused. Similar predictions can be used to determine whether and where to migrate data volumes so as to maintain sufficient capacity across a group of resources.
