Abstract: Example implementations relate to preserving data availability in a constrained deployment of an HA system (e.g., an HA storage system) in the presence of pending faults. According to an example, a first arbiter, acting as a witness to facilitate maintaining quorum for the HA system, and a first node are provided within a first failure domain; and a second arbiter, serving as a backup arbiter, and a second node are provided within a second failure domain. Responsive to receipt of an indication of a pending fault impacting the first failure domain by a member of the current configuration of the HA system, establishment of a new configuration, excluding the first arbiter and including the second arbiter, is initiated. Responsive to a majority of the current configuration installing the new configuration, the second arbiter is enabled to serve as the active arbiter by transferring state information to the second arbiter.

Abstract: A source system generates snapshots of collected data. The snapshots have respective associated time references. Responsive to a request from a target system for data collected over a time interval, the source system generates a subset of the data collected by determining a start snapshot and an end snapshot. The start snapshot and the end snapshot are determined as a pair of snapshots that have respective associated time references that are most closely spaced and are inclusive of the time interval. The source system determines a difference in the data included in the end snapshot and the start snapshot and provides the subset of the data as the difference in the data included in the end snapshot and the start snapshot.

Abstract: Cluster groups define a relationship between clusters in an HCI system. New cluster groups may be created, and a cluster may be added or removed from an existing cluster group. A method and system are disclosed to support a dynamically scaled hyperconverged system with non-overlapping and overlapping cluster groups. A dynamically scalable hyperconverged system may allow for piece-wise upgrades while supporting inter-operable and non-interoperable components having a secure intercommunication capability. A system is disclosed for scaling a single managed hyperconverged infrastructure (HCI) where all components are allowed to run a compatible communication protocol (e.g., interoperable communication protocol) but are not required to operate an interoperable software version. Further, methods are disclosed to a) illustrate consolidation of backups for a cluster of HCI nodes running interoperable and non-interoperable data exchange protocols; and b) dynamically organize groups of clusters to enforce interoperability requirements and simplify network configuration among these clusters.
