    摘要: Techniques for taking and managing snapshots comprise: capturing a first snapshot of a virtual machine (VM), wherein the first snapshot is a managed snapshot exposed to a virtualization environment and a data storage system environment providing physical storage for data of the VM; capturing a second snapshot of the VM, wherein the second snapshot of the VM is a managed snapshot of the VM is exposed to the virtualization environment and the data storage system environment; and converting the second snapshot of the VM from a managed snapshot of the VM to an unmanaged snapshot of the VM. Subsequent to completing the converting, the second snapshot of the VM that is an unmanaged snapshot is exposed to the data storage system environment and subsequent to completing the converting, the second snapshot of the VM that is an unmanaged snapshot is not exposed to the virtualization environment.

    摘要: A set of one or more logical storage units is provisioned in a data storage system. Each logical storage unit is provisioned with a given storage capacity. A set of one or more object rules is applied to objects stored in the set of one or more logical storage units. The set of one or more object rules is configured to maintain available free storage space in each of the set of one or more logical storage units: (i) consistent with a desired free storage space level and an acceptable free storage space level; and (ii) consistent with an object retention policy comprising a desired retention time value and an acceptable retention time value for a given object.

    摘要: A technique utilizes a group of data protection policies within data storage equipment. The technique involves providing, by the data storage equipment, access to individually invocable data protection services. The data storage equipment is constructed and arranged to invoke each individually invocable data protection service in response to user entrance of a respective data protection rule to protect data within a storage object. The technique further involves forming, by the data storage equipment, a policy group from multiple data protection rules. The technique further involves assigning, by the data storage equipment, the policy group to a set of storage objects to protect data within the set of storage objects. Such a technique enables assignment of multiple and different data protection rules to a storage object all at once. Moreover, if the policy group is modified, the modification may be applied to all storage objects at the same time.

    摘要: Techniques for managing data mobility domains in storage system environments. The techniques employ a multiple master approach, in which each storage system in a storage system domain can function as an owner of the domain. Each domain owner has privileges pertaining to addition of new members to the domain, removal of members from the domain, and modification of domain credentials. When a new storage system is added as a member of the domain, the domain credentials are provided from the domain owner to the new storage system, resulting in the domain credentials being shared among all members of the domain. Domain membership information is also shared among all members of the domain. In this way, the management of storage system domains can be achieved without the need of a domain management server, avoiding a single point of failure or latency and reducing the complexity/cost associated with the domain management server.

    摘要: A method, computer program product, and computing system for receiving a selection of one or more secure snapshots to remove from a storage system. A snapshot deletion key may be received from the storage system. The selection of the one or more secure snapshots and the snapshot deletion key may be provided to a storage system support service. A snapshot deletion response may be received from the storage system support service. The snapshot deletion response and the selection of the one or more secure snapshots may be authenticated via the storage system. In response to authenticating the snapshot deletion response and the selection of the one or more secure snapshots, the one or more secure snapshots may be unlocked for deletion.

    摘要: During preparation for migration of a logical volume from a source data storage appliance to a destination data storage appliance, a determination is made as to whether at least one host that accesses a copy of the logical volume contained in the source data storage appliance is managed by a host administration server. In response to determining that at least one host that accesses the copy of the logical volume contained in the source data storage appliance is managed by the administration server, a rescan request is transmitted to the administration server. The rescan request causes the host administration server to instruct each host that is managed by the host administration server that accesses the copy of the logical volume contained in the source data storage appliance to perform a rescan operation to discover at least one new path to the logical volume.
