    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 storage system may implement dynamic configuration of data volumes. Client utilization of a data volume in a storage system may be tracked or monitored. Based on the utilization of the data volume, configuration recommendations to reconfigure the data volume according to data volume offerings may be determined. The data volume may be configured according to an authorized configuration recommendation. In some embodiments, these recommendations may be provided to a client and selection of the configuration recommendation to perform may be received. In some embodiments, a configuration recommendation may be automatically performed based on previously provided authorization to configure the data volume.

    Abstract: A distributed system may implement opportunistic resource migration to optimize resource placement. Resources may be placed amongst different resource hosts of a distributed system. An evaluation of the current placement may be performed according placement criteria that improve placement of the resources at the distributed system. Based on the evaluation, the prospective migration of resources that exceed an improvement threshold may be identified as candidate resources to migrate. Migration for the candidate resources may be opportunistically performed. In some embodiments, a priority may be assigned to the candidate resources according to which the candidate resources are selected for performing migration.

    Abstract: The estimated rate of work requests expected during a time period at a first block storage device, implemented at a particular server of a storage service, exceeds a provisioned rate of the first device. At a client-side component of the storage service, a different storage server is identified, at which the rate of work requests directed during the time period to a second block storage device is anticipated to be less than the provisioned rate of the second device. At least one admission control parameter of the first device is modified to enable the first storage server to accept work requests at a rate that exceeds the provisioned rate of the first device.

    Abstract: An I/O scheduler can manage and schedule write requests that are sent to a storage device in order to prevent the write requests from dominating a storage buffer of the storage device. The I/O scheduler can monitor the number of I/O requests in the storage buffer and maintain a balance between write requests and read requests in the storage buffer. The I/O scheduler monitor the latency of the storage device in processing write requests and manage the write requests sent to the storage device based on the latency. The I/O scheduler can utilize one or more write thresholds. The write thresholds can define thresholds of the number of write requests in the storage buffer and thresholds for the latency of the storage device in processing write requests. The write threshold can represent acceptable levels of write request in the storage buffer and acceptable latency for write requests.

    Abstract translation: I / O调度器可以管理和调度发送到存储设备的写入请求，以防止写入请求主导存储设备的存储缓冲器。 I / O调度器可以监视存储缓冲区中的I / O请求数量，并在存储缓冲区中保持写入请求和读取请求之间的平衡。 I / O调度器在处理写入请求时监视存储设备的延迟，并根据延迟来管理发送到存储设备的写入请求。 I / O调度器可以利用一个或多个写入阈值。 写入阈值可以定义存储缓冲区中的写入请求数量的阈值以及处理写入请求时存储设备的延迟的阈值。 写入阈值可以表示存储缓冲区中写入请求的可接受水平以及写入请求的可接受延迟。

    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. 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.
