Storage services and systems
View Patent ↗Storage services and systems are provided. Virtual disks include a number of storage states and are associated with storage operations that are provided with the virtual disks. Moreover, a storage management set of executable instructions is configured based on values assigned to the states when the storage operations are performed against the virtual disks. In some embodiments, a selection set of executable instructions permits the selective execution of the storage operations.
1. A method to provide storage operations, comprising:
providing a virtual disk with access to perform a snapshot operation, wherein the virtual disk logically represents storage data on one or more storage devices, wherein the snapshot operation is operable to copy the storage data;
associating state information with the virtual disk, wherein the state information indicates whether the virtual disk is in a state that permits the snapshot operation to be performed;
receiving a request for the snapshot operation to be performed; and
performing the snapshot operation in response to determining that the state information indicates that the virtual disk is in a state that permits the snapshot operation to be performed.
2. The method of claim 1 , wherein the virtual disk is a first virtual disk in a group of virtual disks, wherein the state information associated with the first virtual disk indicates whether every virtual disk in the group is in a state that permits the snapshot operation to be performed on the virtual disk.
3. The method of claim 1 , further comprising:
providing the virtual disk with access to perform a restore operation, wherein the restore operation is operable to restore storage data previously copied by the snapshot operation to the one or more storage devices;
wherein the state information further indicates whether the virtual disk is in a state that permits the restore operation to be performed.
4. The method of claim 1 , wherein the one or more storage devices include a first storage array and a second storage array, wherein the first storage array is a different type of storage array than the second storage array.
5. A storage operation system, comprising:
one or more storage devices;
a virtual disk that logically represents storage data on the one or more storage devices, wherein the virtual disk has associated state information that indicates whether the virtual disk is in a state that permits a snapshot operation to be performed;
a storage management set of executable instructions operable to perform the snapshot operation against the virtual disk in response to determining that the state information associated with the virtual disk permits the snapshot operation to be performed, wherein the snapshot operation is operable to copy the storage data; and
a selection set of executable instructions that permits selective execution of the snapshot operation.
6. The storage operation system of claim 5 , wherein performing the snapshot operation comprises at least one of mirroring the virtual disk to a second virtual disk and backing up the virtual disk to the second virtual disk.
7. The storage operation system of claim 5 , wherein the state information is set at least in part based on a type associated with one or more of the one or more of the storage devices.
8. The storage operation system of claim 5 , wherein the selection set of executable instructions permits selection of a target virtual disk or a storage pool to be used when selectively executing the snapshot operation against the virtual disk.
9. The storage operation system of claim 5 , wherein the virtual disk is a first virtual disk in a group of virtual disks, wherein the state information of the first virtual disk indicates whether every virtual disk in the group is in a state that permits the snapshot operation to be performed on the virtual disk.
10. The storage operation system of claim 5 , wherein the virtual disk, the storage management set of executable instructions, and the selection set of executable instructions participate in a shared storage environment.
11. The storage operation system of claim 5 , wherein the selection set of executable instructions is a graphical user interface (GUI) set of executable instructions.
12. A virtual disk data structure residing on a computer readable medium, comprising:
storage metadata associated with a plurality of storage devices, wherein the metadata logically represents storage data residing on the storage devices;
state information indicating whether the virtual disk data structure is in a state that permits a snapshot operation to be performed to copy the storage data;
a plurality of storage operation mappings providing access to process a plurality of storage operations, wherein the storage operation mappings include a first storage operation mapping that indicates whether the snapshot operation can be performed, based on the state information.
13. The virtual disk data structure of claim 12 , wherein the plurality of storage operation mappings is accessible to a storage management set of executable instructions.
14. The virtual disk data structure of claim 12 , wherein the state information is determined by interfaces associated with a plurality of the storage devices.
15. The virtual disk data structure of claim 12 , wherein the plurality of storage operation mappings is accessible to a selection set of executable instructions.
16. The virtual disk data structure of claim 12 , wherein the snapshot operation is operable to create a frozen image of the storage data.
17. The virtual disk data structure of claim 12 , wherein the virtual disk data structure resides in a volatile memory.
