摘要： The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. When a virtual machine is provisioned, logical storage volumes include a logical metadata storage volume and logical data storage volumes. The logical metadata storage volume stores metadata for the virtual machine such as configuration and log files, swap file, and disk descriptor files. Each disk descriptor file is provided for one logical data storage volume and stores metadata about the logical data storage volume such as size and unique identifying data.

摘要： The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. Logical storage volumes are created from a logical storage container having an address space that maps to storage locations of the physical data storage units. Each of the logical storage volumes so created has an address space that maps to the address space of the logical storage container. A logical storage container may span more than one storage system and logical storage volumes of different customers can be provisioned from the same logical storage container with appropriate security settings.

摘要： The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. When traffic through a particular protocol endpoint is busy, the logical storage volume undergoes a rebind process pursuant to which the logical storage volume is bound to a new protocol endpoint, and the binding to the old protocol endpoint is removed upon completion of all pending input-output commands issued through the old protocol endpoint.

摘要： The storage system exports logical storage volumes that are provisioned as storage objects within logical storage containers. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. A snapshot profile can be separately defined for each of these logical storage volumes, even for those that are within the same storage container. The snapshot profile for a logical storage volume defines whether or not snapshot is enabled for that logical storage volume, the frequency of the snapshot, and the number of snapshots to be retained.

摘要： The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. To facilitate creation and management of logical storage volumes, special application programming interfaces (APIs) have been developed. The special APIs include commands to create a logical storage volume, bind, unbind, and rebind the logical storage volume, extend the size of the logical storage volume, clone the logical storage volume, and move the logical storage volume.

摘要： Techniques for allocating/reducing storage required for one or more virtual machines are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for allocating storage for one or more virtual machines. The method may comprise providing one or more virtual machines. The method may also comprise creating one or more master images containing one or more commonly used blocks. The method may also comprise creating one or more Copy on Write volumes, where each Copy on Write volume may be associated with at least one of the one or more virtual machines and at least one of the one or more master images, and wherein updated blocks may be stored in at least one of the one or more Copy on Write volumes, thereby reducing storage required for one or more virtual machines.

摘要： Computer implemented methods and systems for providing storage virtualization of physical storage include receiving a request for storage from a virtual machine during provisioning of the virtual machine. The request includes a capability and quota requirement for storage as required by the virtual machine. A virtual datastore that satisfies the capability and quota requirements of the request is identified. If not found, one or more volumes, that satisfy the storage requirements, are discovered or created. A virtual datastore is created and maps to one or more volumes which have unique volume identifiers. A unique virtual datastore identifier is generated for the virtual datastore. The virtual datastore identifier is distinct from the volume identifiers of the underlying volumes. The volumes are mapped to the virtual datastore while retaining the virtual datastore identifier for the virtual datastore. The virtual datastore identifier for the virtual datastore is not changed when modifications are made to the physical storage entities mapped to the virtual datastore.
