Abstract: A method according to one embodiment includes sending, from a first system to a second system, a request for a clock value associated with a third system; receiving, from the second system, a clock value associated with the third system and a query clock value determined at the second system; comparing, at the first system, the clock value associated with the third system to the query clock value determined at the second system; determining an amount of time since the third system contacted the second system, in response to determining that the query clock value is greater than the clock value associated with the third system; comparing the difference to a threshold time; determining that the third system is unavailable when the difference exceeds the predetermined threshold time value; and performing one or more predetermined actions at the first system in response to determining that the third system is unavailable.

Abstract: A computer-implemented method according to one embodiment includes receiving, at a storage system, a request to allocate persistent data storage for use by a container within an orchestration system, where the request includes an orchestration system identifier, selecting a storage volume within the storage system for use by the container within the orchestration system, determining a storage identifier for the storage volume within the storage system, and storing, within the storage system, an association between the orchestration system identifier and the storage identifier.

Abstract: For deduplicated data processing hierarchical rate control in a data deduplication system in a computing storage environment, priorities in a hierarchal structure are propagated by defining a relationship between each of a plurality of maintenance tasks and using a resource distribution function for managing and dividing resources between the plurality of maintenance tasks based on a priority for each maintenance task. Each one of the plurality of maintenance tasks is defined to be one of above, below, and at a same level in the hierarchal structure as compared to another one of the plurality of maintenance tasks. The hierarchal structure comprises a tree structure having a plurality of leaf nodes that are actual task and branch nodes that are virtual tasks.

Abstract: Data file in the data deduplication system are associated with a file identifier defined to have a first part identifier for denoting a location of the data file in a storage, and a second part identifier for uniquely identifying the data file in the data deduplication system over time.
