Abstract: An adaptive idle detection method determines whether software defined data centers (SDDCs) in a hyperconverged infrastructure (HCI) environment are idle. Idleness may be quantified via a coefficient of variation (CV) against resource usage, so as to adapt the idle detection method to SDDCs with different hardware specifications and workloads. Management overhead may also be filtered out by the idle detection method, and the idle detection method may use idleness scores to further reduce overhead.

Abstract: Solutions for secure metering of hyperconverged infrastructures are disclosed. Examples include: receiving a security token; accessing a secondary storage (e.g., cold storage, backups) using the security token; determining usage data for the secondary storage; generating a first message digest for a combination of the usage data and the security token; and transmitting, to a metering server, the usage data and the first message digest. In some examples, the combination of the usage data and the security token comprises a concatenation of the usage data and the security token. In some examples, the metering server requests verification usage data from the secondary storage, generates a second message digest for a combination of the verification usage data and the security token, and compares the first message digest with the second message digest. Examples do not persist the security token on customer premises. Examples leverage the usage data to optimize the secondary storage.

A standby path is selected for any other host that is neither an object owner or a component owner. The selected paths are provided to an initiator so as to enable the initiator to choose at least one of the paths to access the target for the input/output.

Abstract: The current document is directed to methods and subsystems that manage submitted code changes for processing by continuous-integration/continuous-delivery/deployment systems. In disclosed implementations, code changes are processed as quickly as possible, when the code changes are flagged as being urgent. Non-urgent code changes are evaluated for the possibility of merging the non-urgent code changes with additional, subsequently submitted code changes in order to more efficiently employ computational resources needed for processing the code changes. When there is a code change, waiting for processing, with which a submitted code change can be merged, the submitted code change is merged with the waiting code change so that the merged code changes can be together verified.
