Abstract: A method for using a reference volume for initial synchronization of a replicated volume group. The method includes initiating a replication and synchronization operation between a parent virtual machine and a child virtual machine, and specifying a parent virtual machine to be used for replication and a subsequent synchronization. The method further includes accessing a point in time snapshot of the parent virtual machine, coordinating with a secondary site to obtain an image of the parent reference volume at said point in time, and copying the common regions from a parent reference volume to a new volume. The differences between the parent reference volume and the new volume are transmitted and are applied to the new volume to synchronize the child virtual machine on the secondary site to the child virtual machine on the primary site, wherein the child and the parent may be in different virtual machine groups.

Abstract: A computer-implemented method for recovering primary sites after failovers to remote secondary sites may include: 1) identifying a primary system configured to replicate data to both a local bunker system and a remote secondary system, 2) failing the primary system over to the remote secondary system, 3) replicating, to the local bunker system, data changes made on the remote secondary system, and then 4) updating the primary system with the data changes stored on the local bunker system. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Various computer-implemented methods for securing data of replicated volumes are disclosed. In one example, an exemplary method for performing such a task may include: 1) identifying a set of plexes of a replicated volume, 2) identifying, within the set of plexes, at least one non-trusted plex, 3) intercepting data to be replicated to the non-trusted plex, 4) encrypting the data to be replicated to the non-trusted plex, and then 5) writing the encrypted data to the non-trusted plex. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A method and apparatus for achieving high availability for applications and optimizing power consumption within a datacenter is provided. In one embodiment, a method for providing high availability and optimizing power consumption within a datacenter comprises upon execution of an application at a target node amongst a plurality of nodes in a datacenter, selecting a failover target node amongst the plurality of nodes for the application, and reserving a failover capacity of at least one resource of the selected failover target node.
