  • Publication number: 20210224355
    Abstract: Examples are disclosed that relate to encoding data on a data-storage medium. The method comprises obtaining a representation of a measurement performed on the data-storage medium, the representation being based on a previously recorded pattern of data encoded in the data-storage medium in a layout that defines a plurality of data locations. The method further comprises inputting the representation into a data decoder comprising a trained machine-learning function, and obtaining from the data decoder, for each data location of the layout, a plurality of probability values, wherein each probability value is associated with a corresponding data value and represents the probability that the corresponding data value matches the actual data value in the previously recorded pattern of data at a same location in the layout.

  • Publication number: 20210096968
    Abstract: A server system comprising storage devices, processing devices and a storage fabric all operating according to a storage fabric protocol. The storage fabric comprises a plurality of individual switches having a modular design from which an overall switch is built, and the individual switches have individual respective configuration settings which determine which processing devices are allocated to use which of the storage devices. The system comprises an API enabling a software control function to configure the overall switch. The API is operable to receive from the control function an overall mapping of the storage devices to the processing devices instead of requiring the individual configuration settings of each of the individual switches to be specified by the control function, the API being configured to convert the overall mapping into the individual configuration settings of the individual switches to produce the overall mapping.

  • Publication number: 20190245923
    Abstract: A server system comprising processing devices, disks and a storage fabric, all arranged to operate according to a storage fabric protocol in order to communicate between the processing devices and the storage devices over the storage fabric, wherein the storage fabric is settable with a mapping determining which of the processing devices are allocated to use which of the storage devices in providing said services to the client systems. The system comprises a control function arranged to dynamically adapt the mapping in response to either: (i) failure or other downtime of one of the processing devices, storage devices, a component of the storage fabric or a connection in the storage fabric; or (ii) a current demand for the services from the client systems.

  • Publication number: 20180081379
    Abstract: Low cost storage for write once read rarely data is described. In an embodiment a storage device comprises a plurality of hard disk drives connected to a server via an interconnect fabric. The storage device comprises a cooling system which is only capable of cooling a first subset of the hard disk drives and a power supply system which is only capable of powering a second subset of the hard disk drives and in some examples, the interconnect fabric may be only capable of providing full bandwidth for a third subset of the hard disk drives. Each subset may comprise only a small fraction of hard disk drives. A control mechanism, which may be implemented in software, is provided which controls which hard disk drives are active at any time in order that the constraints set by the cooling and power supply systems and interconnect fabric are not violated.

  • Patent number: 9792427
    Abstract: Methods for enforcing confidentiality and integrity of code and data while running the code over the data in a distributed computing system are described. In an embodiment each machine which processes data within the system provides a secure sub-system which is protected from other parts of the machine and which receives encrypted data and encrypted code, processes the data using the received code and outputs encrypted data. When establishing the secure sub-systems, keys are exchanged between the client and secure sub-systems and the secure sub-systems provide an attestation confirming the identity of the code running in the secure sub-systems and confirming that the code is running on genuine secure sub-systems. In another embodiment a data-flow computation system is described in which chunks of input data, each comprising an identifier, are authenticated/encrypted. The identifiers are used within the system to confirm that each chunk is processed exactly once.

  • Patent number: 9244615
    Abstract: Controlling data storage input/output requests is described, for example, to apply a policy to an end-to-end flow of data input/output requests between at least one computing entity and at least one store. In various examples a plurality of queues are configured at one or more stages of the end-to-end flow and controlled to adhere to a policy. In examples, each stage has a control interface enabling it to receive and execute control instructions from a controller which may be centralized or distributed. For example, the control instructions comprise queuing rules and/or queue configurations. In various examples queues and queuing rules are dynamically created and revised according to feedback about any of: flow behavior, changes in policy, changes in infrastructure or other factors. In examples, high level identifiers of the flow endpoints are resolved, on a per stage basis, to low level identifiers suitable for use by the stage.
