  • Publication number: 20180019592
    Abstract: A method of adding a power feed to electrical systems includes coupling a set of input lines to a power source such that the input lines are connected to at least one phase of AC power from the power source, and coupling a set of backfeed lines to an output receptacle in a power distribution unit. The output receptacle may be connected in parallel with at least one other output receptacle that is supplying primary power to systems in the data center. The set of backfeed lines and the set of input lines may be tested to determine a match between a pair of lines in the set of backfeed lines and a pair of lines in the set of input lines. Determining the match may include matching the phase of the pair of backfeed lines with the phase of the pair of input lines.

  • Publication number: 20180004801
    Abstract: Nodes of a database service may receive a read request to perform a read of a record stored by the database service and a transaction request to perform a transaction to the record. First and second indications of time may be associated with the read and transaction, respectively. A potential read anomaly (e.g., fuzzy read, read skew, etc.) may be detected based, at least in part, on a determination that the first indication of time is within a threshold value of the second indication of time. In response to detecting the potential read anomaly, the read may be performed after the transaction specified by the transaction request, regardless of whether the first indication of time is indicative of an earlier point in time than the second indication of time.

  • Publication number: 20180004954
    Abstract: A multi-phase boot operation of a virtualization manager at a virtualization host is initiated at an offload card. In a first phase of the boot, a security key stored in a tamper-resistant location of the offload card is used. In a second phase, firmware programs are measured using a security module, and a first version of a virtualization coordinator is instantiated at the offload card. The first version of the virtualization coordinator obtains a different version of the virtualization coordinator and launches the different version at the offload card. Other components of the virtualization manager (such as various hypervisor components that do not run at the offload card) are launched by the different version of the virtualization controller.

  • Publication number: 20170308419
    Abstract: A service provider system may provide virtualized computing services to clients, including encapsulating services that call other (encapsulated) services. Once configured to delegate parameters to encapsulated services, an encapsulating service (and its API) may not need to be modified when an encapsulated service (or its API) is modified to support more, fewer, or different features or corresponding arguments. For example, an encapsulating service may receive a service request call from a client that includes arguments for an encapsulated service (e.g., as header information, or as an opaque block or uninterpreted key-value dictionary) and may call the encapsulated service, blindly passing along those arguments. An encapsulating service may access stored policy-based arguments or obtain arguments from a central service. Arguments passed to an encapsulated service may override default parameters of the service.

  • Publication number: 20170300552
    Abstract: A distributed data store may maintain versioned hierarchical data structures. Different versions of a hierarchical data structure may be maintained consistent with a transaction log for the hierarchical data structure. When access requests directed to the hierarchical data structure are received, a version of the hierarchical data structure may be identified for processing an access request. For access requests with snapshot isolation, the identified version alone may be sufficient to consistently process the access request. For access requests with higher isolation requirements, such as serializable isolation, transactions based on the access request may be submitted to the transaction log so that access requests resulting in committed transactions may be allowed, whereas access requests resulting in conflicting transactions may be denied.

    Abstract: Managing power feeds includes monitoring a waveform of a high-voltage power feed supplied to an electrical load to detect potential interruption of the high-voltage power feed and switching to another power feed to supply power to the electrical load in response to identifying the waveform pattern. Monitoring a waveform includes processing the waveform to determine if one or more waveform patterns are present in the waveform. A waveform pattern indicates, by its presence in a waveform of a power feed, a power event associated with the power feed, and some waveform patterns indicate potential interruption of the power feed. Switching to another power feed in response to determining potential interruption of the power feed based on waveform monitoring enables an uninterrupted power supply.

  • Publication number: 20170289230
    Abstract: A streaming source sends streaming content to a display device. A camera captures images of the display device playing the streaming content and/or a user's interaction with the display device along with the displayed response to the user's interaction. The captured content is analyzed to determine, for example, image quality characteristics of the displayed content, a user experience associated with the displayed content or whether the displayed content matches an expected outcome associated with testing input. Information determined from the analysis of the captured content may be used to adjust characteristics of the streaming content, such as streaming parameters at the streaming source or configuration of the display device. A testing system may analyze the captured content to evaluate performance of the streaming system. Results of the testing may be sent to a data store and/or used to mitigate a poor user experience such as poor image quality.

  • Publication number: 20170277715
    Abstract: A distributed file storage services (DFSS) that provides low latency (LL) and high throughput (HT) modes for file systems. A HT metadata subsystem (HTMS) may use a distributed transaction system for data and metadata reads and writes for file systems in HT mode. A LL metadata subsystem (LLMS) may process metadata requests for file systems in LL mode. For metadata read requests, the LLMS may locally cache at least some of the file system metadata. For metadata write requests, the LLMS may write entries to a journal and notify the access node after the entries are committed to the journal. Data reads and writes for file systems in LL mode may be handled similarly to data reads and writes for file systems in HT mode. A file system may be converted from LL to HT mode, or from HT to LL mode.

  • Publication number: 20170277709
    Abstract: An LL server (LLS) may process metadata requests for a file system in LL mode in a distributed file storage services (DFSS). For requests that require allocating blocks to file system objects in the backing store, instead of relying on distributed transactions used for file systems in high throughput (HT) mode, a pool of blocks may be pre-allocated for the LL file system in the backing store, and a free block list may be maintained in local memory of the LLS. When a metadata operation requires blocks to be allocated, the blocks are assigned to the respective object from the blocks in the pool. A background process may allocate new blocks in the pool upon the number of blocks dropping below a threshold, or upon block allocation rate for the file system increasing.

  • Publication number: 20170277713
    Abstract: A low latency metadata subsystem for file systems in low latency (LL) mode in a distributed file storage service (DFSS). An LL server (LLS) may receive metadata requests from an access node of the DFSS. For read operations, the LLS may check a local cache of metadata and, for cache hits, retrieve the metadata from the cache. For cache misses, the metadata may be fetched from the storage subsystem of the DFSS and cached. For write operations, the LLS may write entries into a journal for the file system and notify the access node after the journal entries are committed to the journal; the journal entries are asynchronously committed in the storage subsystem. The access node may communicate with the storage subsystem to perform data reads and writes for the LL file system.

    Abstract: A database system may maintain a plurality of log records at a distributed storage system. Each of the plurality of log records may be associated with a respective change to a data page. Upon detection of a coalesce event for a particular data page, log records linked to the particular data page may be applied to generate the particular data page in its current state. Detecting the coalesce event may be a determination that the number of log records linked to the particular data page exceeds a threshold.

  • Publication number: 20170270004
    Abstract: A storage manager may be used to perform a decoding operation using a transmission time refinement technique on a data object stored in a storage system, such as an object-redundant storage system. The decoding operation may include requesting groups of corresponding blocks from storage devices of the storage system. The storage manager may maintain connections to a connection group of the storage devices and may iteratively request corresponding blocks of the data object from one or more various request groups of the storage devices of the connection group. The storage manager may evaluate performance of the request groups in sending the corresponding blocks of the data object and may modify the membership of the request groups for requests for subsequent blocks of the data object based at least in part on the performance of the request groups.

  • Publication number: 20170257973
    Abstract: Deployable barriers are reversibly deployed in a data center hall to partition the data center. The hall is partitioned into an operational area, where rack computer systems are installed, a non-operational area, and a staging area where support infrastructure is at least partially installed. A barrier can be collapsed to incorporate the staging area into the operational area, thereby expanding the operational area, when rack computer systems are to be installed in the staging area. A barrier deployed in the non-operational area establishes another staging area. A barrier includes a deployment mechanism which extends through a space in the data center to enable a partition to be extended to partition the hall. The barrier can be mounted and deployed on support infrastructure, so that the deployed barrier and a side portion of the support infrastructure collectively partition the hall.

  • Publication number: 20170255589
    Abstract: Methods and apparatus for lifecycle support for storage objects are disclosed. A storage medium stores program instructions that when executed on a processor implement a storage lifecycle manager of a multi-tenant storage service. The lifecycle manager determines a lifecycle policy to be implemented for a storage object. The policy indicates lifecycle transitions of the object, including a transition from a first service level to a second service level. The first service level and the second service level may each specify a maximum number of versions of the storage object. The lifecycle manager initiates modification operations corresponding to the storage object's data in accordance with the lifecycle policy, and verifies that the modification operations succeeded. The lifecycle manager provides, in response to a query, an indication of a current service level of the storage object.
