  • Patent number: 10318346
    Abstract: Data stores may implement prioritized scheduling of data store access requests. When new access requests are received, the new access requests may be scheduled for prioritized execution on processing resources. Access requests that are currently being executed with prioritized execution may be reprioritized to make additional capacity for prioritized execution of the new access requests. Prioritized execution may be automatically enabled or disabled for a data store based on monitoring of performance metrics for executing access requests.

    Abstract: A distributed file system that includes multiple computing node tiers. Each of at least some of the multiple computing node tiers has multiple computing nodes having like characteristics. The distributed file system also has an executable component in the form of a distribution component that comprises logic that distributes state of file system entities amongst the computing node tiers. The distribution is performed so that latency of file system requests are reduced due to state responsive to many requests being much closer latency wise to the file system requestor(s). Furthermore, the distribution considers durability guarantees of the state, thereby meeting durability guarantees.

  • Patent number: 10129358
    Abstract: Some embodiments provide partitioned serialized caching and delivery of large sized content and files. Some embodiments partition requests for large sized content into segment requests with each segment request identifying a different byte range of the requested content. Each segment request is hashed to identify a particular server from a set of servers tasked with caching and delivering a different segment of the requested content. In this manner, no single server caches or delivers the entirety of large sized content. The segment requests are distributed serially across the set of servers so that the segments are passed in order, wherein the serial distribution involves handing-off the requesting user's connection serially to each server of the set of server in the order with which the set of servers deliver the content segments.

  • Patent number: 10075518
    Abstract: Systems for managing user collaboration over objects stored on a cloud-based service platform. A server in a cloud-based platform maintains a set of read/write metadata that is associated in one-to-one correspondence to stored objects that are accessible by two or more collaborators. The server does not maintain a list of peers that communicate over peer-to-peer connections, rather the server exposes a semaphore for access to the metadata that pertains to a particular one of the stored objects. The server responds to download requests from the collaborators so as to deliver executable signaling protocol computer code to the collaborators' user devices. The signaling protocol code includes semaphore access by the collaborators' user devices using an application programming interface. Two or more accesses over the same semaphore establishes a leader and at least one follower. Corresponding ephemeral peer-to-peer connections are established between the leader and the at least one follower.

The second storage device is configured to receive a request addressed to the representative address from the information processor apparatus, and transfer the request to a third storage device among the plurality of storage devices to process the request. An assigned representative address may be canceled when a storage device fails and an internal IP address may be assigned. Storage devices may be selected based on load and the need for cable or hardwired connections may be reduced.

  • Patent number: 9665415
    Abstract: A low-latency internode messaging scheme bypasses the nodes' I/O stacks to use fabrics or links that support memory process logic (e.g., SMI3) or electrical process logic (e.g., PCIe) on the “node side” between the nodes and a pooled memory controller (or pooled storage controller), and on the “pooled side” between that controller and its pooled memory or storage. The controller may translate and redirect messages and look up addresses. The approaches accommodate 2-level memory (locally attached node memory and accessible pooled memory) with either or both levels private, globally shared, allocated to a subset of the nodes, or any combination. Compatible interrupt schema use the messaging links and components.

  • Patent number: 9652296
    Abstract: A hypervisor receives, from a second host at a third host, at a second time after a first time, a first plurality pages. The first plurality of pages were copied at the first time, from a first host to the second host. The hypervisor receives a mapping at the third host, sent from the second host. The mapping indicates a first location of a second plurality of pages and a second location of a third plurality of pages. The hypervisor detects a page fault at the third host. The page fault is associated with a required page that is absent from the third host. Responsive to detecting this, the hypervisor queries the mapping, to determine a source location of the required page and identifies a source host for the source location. The hypervisor receives the required page, from the source host at the third host.

  • Patent number: 9621399
    Abstract: Embodiments of a distributed caching system are disclosed that cache data across multiple computing devices on a network. In one embodiment, a first cache system serves as a caching front-end to a distributed cluster of additional cache systems. The first cache system can distribute cache requests to the additional cache systems. The first distributed caching system can also serve as a cache server itself, by storing data on its own internal cache. For example, the first cache system can first attempt to find a requested data item on the internal cache, but, if the lookup results in a cache miss, the first cache system can search the additional cache systems for the data. In some embodiments, the first cache system is configured to identify additional requests for the first data item and duplicate the requested data item in order to respond to the additional requests, which allows for greater responsiveness to requests.

  • Patent number: 9582329
    Abstract: Aspects include computing devices, systems, and methods for implementing scheduling an execution process to an execution processor cluster to take advantage of reduced latency with a victim cache. The computing device may determine a first processor cluster with a first remote shared cache memory having an available shared cache memory space. To properly schedule the execution process, the computing device may determine a second processor cluster with a lower latency to the first remote shared cache memory than an execution processor cluster scheduled with the execution process. The second processor cluster may be scheduled the execution process, thus becoming the execution processor cluster, based on a size of the available shared cache memory space and the latency of the second processor cluster to the first remote shared cache memory. The available shared cache memory space may be used as the victim cache for the execution process.

  • Patent number: 9569267
    Abstract: The present disclosure is directed to hardware-based inter-device resource sharing. For example, a remote orchestrator (RO) may provide instructions to cause a device to make at least one hardware resource available to other devices. An RO module in the device may interact with the RO and may configure a configuration module in the device based on instructions received from the RO. The configuration module may set a device configuration when the device transitions from a power off state to a power on state. The device may also comprise a processing module to process data based on the device configuration, interface technology (IT) and at least one hardware resource. The interface technology may allow the processing module and the at least one hardware resource to interact. The RO module may configure the IT to allow the at least one hardware resource to operate locally or remotely based on the instructions.
