Abstract: A hydraulically-powered subsea tool system has a tool (26) and a tool power unit (12). The tool (26) communicates with a first connector element (30) on a hydraulic drive circuit (82). The tool power unit (12) has a hydraulic supply circuit (88) communicating with a second connector element (20). The connector elements are wet-mated with each other to connect the circuits for powering the tool. The circuits are pressure-compensated by respective compensators (136,90). When the circuits are connected, a valve (140) is operable to transfer pressure compensation of one of the circuits from the compensator (136) of that circuit to the compensator (90) of the other circuit. The valve (140) suitably transfers pressure compensation of the drive circuit from a drive circuit compensator to a supply circuit compensator.

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.

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.

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.

Abstract: Methods of classifying a storage traffic stream in a shared storage network are described. In an embodiment, an identifier for the entity generating the stream is generated, where this entity may, for example, indicate a virtual machine, program, session, physical machine, user or process. The identifier is then shared with at least one processing layer along a path of the storage traffic stream between the generating entity and the storage device which stores the file to which the traffic stream relates. In various embodiments, the identifier may then be used by any processing layers which receive it, to selectively handle traffic streams based on the generating entity. The identifier may be shared when the traffic stream is created or subsequently and in various embodiments, the identifier is shared in a second exchange of messages, following the creation of the traffic stream and prior to any other traffic.
