Abstract: A method for maintaining a mapping structure for maintaining metadata for snapshots in a virtualized storage environment, includes taking a snapshot of a virtual disk, generating an entry in a metadata structure for the snapshot, wherein the entry includes metadata for blocks in the snapshot that have been modified since a preceding snapshot and lazily generating an entry in the mapping structure for the snapshot, wherein the entry includes values for each block in the snapshot, wherein a value for a block indicates a presence of metadata in the metadata structure for the block or an absence of metadata in the metadata structure for the block.
Abstract: Examples described herein may provide cluster check services which may determine whether at least one infrastructure dependent virtual machine (e.g., at least one domain controller and/or at least one DNS server) is located outside of a cluster. In this manner, the storage utilized by at least one of the infrastructure dependent virtual machines may not be part of the cluster itself, which may reduce and/or avoid failure and/or downtime caused by unavailability of the service(s) provided by the infrastructure dependent virtual machine.
Abstract: An improved architecture is provided which enables significant convergence of the components of a system to implement virtualization. The infrastructure is VM-aware, and permits scaled out converged storage provisioning to allow storage on a per-VM basis, while identifying I/O coming from each VM. The current approach can scale out from a few nodes to a large number of nodes. In addition, the inventive approach has ground-up integration with all types of storage, including solid-state drives. The architecture of the invention provides high availability against any type of failure, including disk or node failures. In addition, the invention provides high performance by making I/O access local, leveraging solid-state drives and employing a series of patent-pending performance optimizations.
Abstract: Examples described herein may include migration of data associated with a service to a container. An example method includes creating of a user virtual machine associated with a service and an associated virtual disk storing data associated with running the service, and creating a volume group and an associated storage container at a node of a computing system. The example method further includes storing a cloned version of the virtual disk into the storage container, and, in response to discovery of the cloned version of the virtual disk in the storage container, mounting the cloned version of the virtual disk on the volume group to provide access to clients running the service.

Abstract: A system and method include classifying and assigning virtual disks accessed from compute only nodes. The method determines, by a management processor of a virtual computing system, characteristics for a plurality of virtual disks hosted on a plurality of hyper converged nodes in a cluster of nodes in the virtual computing system. The method further classifies, by the management processor, each of the plurality of virtual disks based on the determined characteristics and identifies, by the management processor, one of the plurality of virtual disks to host data for a virtual machine on a compute only node based on the classification to spread out input-output demand in the cluster, reducing probability of input-output bottlenecks and increasing cluster-wide storage throughput. The method also assigns, by the management processor, the identified virtual disk to host data for the virtual machine located on the compute only node.
Abstract: Systems for achieving and maintaining a specified state of a computing resource in a distributed computing environment. A method embodiment commences upon receiving one or more specification parameters that describe a desired target state associated with a particular computing resource and/or of a particular computing environment. The specification parameters that characterize the desired target state of a resource are recorded in a target state data structure. Periodically, an agent issues a state progression query to determine if the computing resource has reached its desired target state. The query is then processed by collecting state parameters that describe the then-current state of the computing resource or environment. The target state data structure is accessed to identify one or more state differences between the desired target state and the then-current state of the particular computing resource and/or its particular computing environment.

Abstract: Systems for alerting in computing systems. A method commences by defining a plurality of analysis zones bounded by respective ranges of system metric values, which ranges in turn correspond a plurality of system behavior classifications. System observations are taken while the computing system is running. A system observation comprising a measured metric value is classified into one or more of the behavior classifications. Based on the classification, one or more alert analysis processes are invoked to analyze the system observation and make a remediation recommendation. An alert or remediation is raised or suppressed based on one or more zone-based analysis outcomes. An alert is raised when anomalous behavior is detected. The system makes ongoing observations to learn how and when to classify a measured metric value into normal or anomalous behaviors. As changes occur in the system configuration, the analysis zones are adjusted to reflect changing bounds of the zones.
