Abstract: A technique provides efficient data failover by creation and deployment of a protection policy that ensures maintenance of frequent common snapshots between sites of a multi-site data replication environment. A global constraint optimizer executes on a node of a cluster to create the protection policy for deployment among other nodes of clusters at the sites. Constraints such as protection rules (PRs) specifying, e.g., an amount of tolerable data loss are applied to a category of data designated for failover from a primary site over a network to a plurality of (secondary and tertiary) sites typically located at geographically separated distances. The optimizer processes the PRs to compute parameters such as frequency of snapshot generation and replication among the sites, as well as retention of the latest common snapshot maintained at each site to create a recovery point and configuration of the protection policy that reduces network traffic for efficient use of the network among the sites.

Abstract: Methods, systems and non-transitory computer readable media for handling IP network addresses in a virtualization system. Embodiments are configured to receive, from a cloud provider, a cloud provider media access control address to assign to a network interface of a computing node. Also received from the cloud provider is a cloud provider's IP address associated with the cloud provider's media access control address. A virtual machine on the computing node is configured such that the cloud provider's IP address serves as an IP address of the virtual machine and such that a virtualization system media access control address serves as a MAC address of the virtual machine. The virtualization system correlates the cloud provider's media access control address to the IP address of the virtual machine. In some cases, the cloud provider's media access control address stored in a virtual switch of a hypervisor.

Abstract: An illustrative embodiment disclosed herein is an apparatus including a processor having programmed instructions that identify a temporary bucket linked to one or more objects of a main bucket. The processor has programmed instructions that detect that an object is uploaded to the main bucket.

Abstract: A system and method determining a Chain Identification Number (CID) of a source snapshot to be replicated from a source site to a target site of a virtual computing system, determining a predetermined number of potential reference snapshots based on the CID of the source snapshot, computing a closeness value between the source snapshot and each of the potential reference snapshots, and creating a list of the potential reference snapshots based on the closeness value of each of the potential reference snapshots. One snapshot from the list is selected as a reference snapshot. The source snapshot is replicated to the target site based on the reference snapshot.

Abstract: Methods, systems and computer readable medium for fast cluster upgrades. The disclosed techniques can be applied during an upgrade of a multi-node cluster when upgrading cluster software and/or hardware. Techniques applied include pausing a virtual machine (VM) at a first node, then communicating then-current states of the paused VM to a second node that executes a migrated clone of the paused VM. While the migrated cloned VM is running at the second node, changes to states of the cloned VM are tracked. When the upgrade of the first node has completed, then when migrating the cloned VM back to the first node, only the tracked state changes of the cloned VM are sent from the second node to the first node. The tracked state changes are used to update the states of the paused VM at the first node. The updated VM is resumed at the first node.

Abstract: In one embodiment, a system for managing communication connections in a virtualization environment includes a plurality of host machines implementing a virtualization environment, wherein each of the host machines includes a hypervisor, at least one user virtual machine (user VM), and a distributed file server that includes file server virtual machines (FSVMs) and associated local storage devices. Each FSVM and associated local storage device are local to a corresponding one of the host machines, and the FSVMs conduct I/O transactions with their associated local storage devices based on I/O requests received from the user VMs. Each of the user VMs on each host machine sends each of its respective I/O requests to an FSVM that is selected by one or more of the FSVMs for each I/O request based on a lookup table that maps a storage item referenced by the I/O request to the selected one of the FSVMs.

Abstract: A scalable multi-cluster resource sharing facility. A global witness process runs on a first computing platform that communicates over one or more networks to any number of nodes situated over two or more clusters. The global witness process listens on the network for occurrences of leadership and/or resource requests from nodes of different clusters. The global witness processes a request by retrieving a resource request and a respective last known state value, comparing the last known state value to a global stored state value, then storing a new state value when the respective last known state value is equal to the stored state value. Any number of contemporaneous requests can be processed by the global witness process, however only one request can be granted. The other requestors each receive a rejection of their resource request when their proffered last known state value is not equal to the stored state value.

Abstract: Systems for cluster computing. A method for detection and remediation of degraded nodes in a cluster commences upon measuring operational aspects of the nodes in the cluster, then determining, based on the measurements and other factors, a suspect set of nodes comprising one or more suspect nodes from the nodes in the cluster that have measurements that are determined to be outliers with respect to remaining nodes that are determined not to be the outliers. A density-based spatial clustering analysis is performed over the suspect set and remediation actions are initiated when results of the density-based spatial clustering analysis identifies a suspect node as being a degraded node.
