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 representative 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 I/O the selected one of the FSVMs.

Abstract: Examples of systems described herein may allow users to change from an application level disaster recovery system (e.g., an application level replication policy) to a share level disaster recovery system (e.g., a share level replication policy). The change may be made such that a base snapshot need not again be taken when beginning operation under the share level replication policy—rather, the base snapshot previously taken during application level replication may be used in some examples. That base snapshot may be leveraged, an initial set of common share snapshots established, and protection maintained going forward on a share level basis.

Abstract: A plurality of different virtualization system images are configured for deployment to a plurality of nodes in heterogeneous environments. Individual ones of the virtualization system images are configured such that once deployed, the nodes form a computer cluster having a storage pool that is shared across the nodes. When configuring the virtualization system images, information that describes the heterogeneous computing environments is accessed, and constraints pertaining the heterogeneous computing environments are reconciled in advance of configuring the different virtualization system images. A common subnet across the heterogeneous environments is established. The plurality of different virtualization system images are configured to access the common subnet once deployed. The common subnet serves as a storage I/O communication path over which a cluster-wide storage pool is implemented.

Abstract: One embodiment of the present invention provides a system that can manage access to a service from a cluster of computing nodes. An instance of the system can operate on a respective computing node. During operation, the system instance can identify an Internet Protocol (IP) address, which provides access to the service from the cluster of computing nodes to a client device at a client site. The system instance can select the computing node for hosting the IP address in the cluster of computing nodes based on a set of selection criteria. The selection is performed independently at the computing node. The system instance can then assign the IP address to the computing node. The assignment allows a request for the service to be directed to the computing node. Subsequently, the system instance can facilitate the service from the cluster of computing nodes based on the request.

Abstract: In some aspects, a non-transitory computer readable storage medium includes instructions stored thereon that, when executed by a processor, cause the processor to create a virtual swap space that is exposed to a core system software, intercept a first page selected by the core system software to be swapped out to the virtual swap space, map the virtual swap space to a physical swap space that is allocated to a type of page associated with first swap metadata, and write the first page to the physical swap space based on the first page having the first swap metadata. In some embodiments, the first page is associated with the first swap metadata.

Abstract: Methods, systems and computer program products for bringing-up a computing cluster on a public cloud infrastructure with techniques utilizing expressed intents (high level descriptions of desired configuration) and asynchronously receiving configuration status messages from the public cloud infrastructure. The method includes a cloud management computing system transmitting to the public cloud infrastructure a first expressed intent for bringing-up a computing cluster. The cloud management computing system asynchronously receiving periodic status messages comprising cluster status data from the public cloud infrastructure reflecting a current configuration state of the computing cluster. The system determines, based on the cluster status data, whether the first expressed intent for the computing cluster has been achieved.

Abstract: Systems for application configuration backup and restore. Techniques establish high frequency restore points of application configuration metadata. Processing commences upon receiving instructions to periodically take snapshots of application configuration metadata. To avoid incurring unnecessary costs to process snapshots of application configuration metadata when the application configuration metadata is slow-changing, the method performs a low-cost check to get the latest update time of the application configuration metadata. That time is compared to the time of the most recent snapshot of the application configuration metadata. When the time of the latest update time of the application configuration metadata is equal to the time of the most recent snapshot of the application configuration metadata, then rather than incurring the cost of generating a duplicate snapshot, the method waits for a duration without generating a new snapshot.

Abstract: Placement scenario optimization mechanisms for automatic placement of computing entities onto nodes of a running multi-node computing cluster. A set of failure mode parameters define a high-availability requirement of the multi-node computing cluster. In advance of a failure event, and responsive to a determination that a then-current computing entity placement does not satisfy the high-availability requirement, the cluster is analyzed and a plurality of feasible placement scenarios are generated. Optimization criteria are applied to the feasible placement scenarios such that a best choice from among the feasible placement scenarios is identified and applied to the virtual machine placements over the cluster. A change monitoring and detection facility continually observes the multi-node computing cluster to detect a change of a failure mode parameter or to detect a change to the configuration of the virtual machines.

Abstract: In accordance with at least some aspects of the present disclosure, an apparatus is disclosed. In some embodiments, the apparatus includes a processor and a memory. In some embodiments, the memory includes programmed instructions that, when executed by the processor, cause the apparatus to receive a snapshot of a virtual object running on a first node, determine an original configuration associated with the virtual object from the snapshot of the virtual object, determine a resource need for the virtual object from the original configuration, determine that an available resource at the recovery node is insufficient to meet the resource need of the virtual object, generate a reconfigured configuration from the original configuration based at least on the resource need, and recover the virtual object at the recovery node based on the reconfigured configuration.

Abstract: A system is provided that enables efficient traffic forwarding in a hypervisor. During operation, the hypervisor determines that a packet is from a first virtual machine (VM) running on the hypervisor and destined to a second VM running on a remote hypervisor. The hypervisor then includes a virtual local area network (VLAN) identifier of a transit VLAN (TVLAN) in a layer-2 header of the packet. The TVLAN is dedicated for inter-VM traffic associated with a distributed virtual routing (DVR) instance operating on the hypervisor and the remote hypervisor. Subsequently, the hypervisor sets a first media access control (MAC) address of the hypervisor as a source MAC address and a second MAC address of the remote hypervisor as a destination MAC address in the layer-2 header. The hypervisor then determines an egress port for the packet based on the second MAC address.

Abstract: An identity authentication management (IAM) service is established as a master over a master identity database of the centralized identity authentication management service. When adding an additional node to the computing infrastructure, a non-master copy of the master identity database is distributed to the additional node. Ongoing coordination between the master identity database and the non-master copy is established so as to synchronize differences between the master identity database and the non-master copy of the identity database. The additional node hosts a fully-functional authentication management service using the non-master copy of the master identity database and is able to respond to READ requests for data by accessing the non-master copy—without interaction with the centralized identity authentication management service.
