摘要： Techniques are disclosed relating to storing location information about storage nodes in cookies. A cloud-based service may send location requests to an orchestration service that instantiated storage nodes included in a storage cluster of the cloud-based service. The cloud-based service may receive location information that identifies in which computer zone that a given storage node is located. The cloud-based service may store the location information in cookies at a metadata store that is shared among the storage nodes. The cloud-based service may receive, from a client node, a search request to identify ones of the storage nodes that store particular data. The cloud-based service may return a set of cookies corresponding to identified storage nodes. The set of cookies may enable the client node to determine whether there is a storage node that stores the particular data and is within the same computer zone as the client node.

摘要： This document describes systems and techniques for deriving identity and root keys for embedded systems. In aspects, a boot process and key manager of an embedded system may implement a secure or trusted boot process for embedded systems in which code of next-level boot loader or software image is verified using root keys or other protected information before execution of the boot process is passed to the next stage in the boot process. Alternatively or additionally, the key manager may enable sealing and attestation of various levels of root and identity keys to enable respective verification of software or hardware throughout a life cycle of a device to prevent unauthorized access to protected or private code of an embedded system. By so doing, the described aspects may enable an embedded system with a secure boot process and robust identity and root key management system.

摘要： An EtherCAT device with a node for use in an EtherCAT network is disclosed. The EtherCAT device includes: a clock circuit; a clock input to receive an input clock signal; a clock output to send an output clock signal; and control logic. The control logic is to determine whether to operate the EtherCAT device in a clock generation mode or a clock propagation mode, wherein in the clock generation mode, the clock circuit is to drive an oscillator to generate the input clock signal; and in the clock propagation mode, the clock circuit is to receive the input clock signal from another node in the EtherCAT network. The control logic is further to control the clock circuit to output the output clock signal for a subsequent node in the EtherCAT network based upon the input clock signal.

摘要： A method, computer system, and a computer program product are provided for managing an accelerated shutdown of a networked system having a having a plurality of nodes. The system to be shutdown is analyzed and a priority order is determined for the nodes. An interval period is also determined between each node according to the priority order. A leaf node set is constructed according to different shutdown types required for each node and a dependency tree is constructed by analyzing the leaf node sets. Each node is then shutdown according to the tree and the interval period determined. The dependency tree and the interval period is iteratively modified during the node shutdown until all nodes and ultimately the system shutdown has been completed.

摘要： The present invention relates to a method, to a computer program containing instructions and to an apparatus for performing a boot process for a system that supports redundant copies of boot images. In a first step, an active copy of the boot images is determined (S1). Then the active copy of the boot images is processed (S2). In response to a successful boot process, another copy of the boot images is then set (S3) as the active copy for a subsequent boot process.

摘要： The present disclosure relates to information processing methods, physical machines, and peripheral component interconnect express (PCIE) devices. In one example method, a PCIE device receives, in a live migration process of a to-be-migrated virtual machine (VM), a packet corresponding to the to-be-migrated VM, where the to-be-migrated VM is one of a plurality of VMs. The PCIE device determines a direct memory access (DMA) address based on the packet. The PCIE device sends the DMA address to a physical function (PF) driver.

摘要： A method of operating the physically unclonable function (PUF)-based key management system includes upon receiving a key generation request including a parameter, a load balancer dispatching a key generation request including a parameter from an external device according to workloads of a plurality of key management components (KMCs). A KMC having minimum workload among the plurality of KMCs is designated as the key-generation KMC and the key generation request is dispatched thereto, and remaining KMCs of the plurality of KMCs are designated as backup KMCs. The method further includes the key-generation KMC generating a key according to the parameter and a first PUF sequence, transmitting the key and an identifier associated therewith to the backup KMC via a backup channel, and the backup KMC generating a wrapped key according to the key and a second PUF sequence.
