  • Patent number: 10896086
    Abstract: Mechanisms for controlling access to storage volumes on the secondary storage system is provided. A determination is made as to whether a first site computing device has sent a notification of a failure condition of a first site. In response to a determination that the notification of the failure condition of the first site has not been received, secondary workloads of a second site computing device are permitted to access storage volumes on the secondary storage system. In response to a determination that the notification of the failure condition of the first site has been received, a mode of operation of the second site is modified from a normal mode of operation to a failure mode of operation. In the failure mode of operation, the storage system controller of the second site blocks at least a portion of access requests from secondary workloads of the second site computing device.

  • Patent number: 10810015
    Abstract: Approaches are described for enabling a host computing device to store credentials and other security information useful for recovering the state of the host computing device in a secure store, such as a trusted platform module (TPM) on the host computing device. When recovering the host computing device in the event of a failure (e.g., power outage, network failure, etc.), the host computing device can obtain the necessary credentials from the secure store and use those credentials to boot various services, restore the state of the host and perform various other functions. In addition, the secure store (e.g., TPM) may provide boot firmware measurement and remote attestation of the host computing devices to other devices on a network, such as when the recovering host needs to communicate with the other devices on the network.

  • Patent number: 10769057
    Abstract: A method, system and computer program product for identifying potential errors in a software product after it is built but prior to release. Negative log reports of previously-build software products containing errors in the code in connection with building these software products are identified. The language of the negative log reports is then vectorized and the vectorized negative log reports are then stored. After vectorizing the language of a build log report upon completion of a build of a software product, the vectorized log report is compared with the stored vectorized negative log reports. The release of the software product will then be halted and the programmer will receive a copy of the negative log report associated with the vectorized negative log report closest in distance to the vectorized log report if the vectorized log report is within a threshold amount of distance to a stored vectorized negative log report.

  • Patent number: 10754718
    Abstract: All modern enterprises rely completely on the continual correct execution of hardware and software resources that constitute the information technology (IT) infrastructure environment for the business. At the same time, hardware and software resources continually evolve, and the enterprise must often make changes to its infrastructure to incorporate the new or updated hardware and software resources. These changes are risky, and failure to properly execute the changes can result in infrastructure roll-backs and other failure modes that are often very disruptive to the enterprise. A guidance system for changes in infrastructure increases the likelihood of successful implementation of the changes. In some implementations, for example, the guidance system provides clear guidelines and checklists that depict success criteria, along with a scoring interface that pro-actively indicates the factors that can go wrong, and how to mitigate and plan for the factors in advance.
