Abstract

A method of providing block-based storage is described. The method comprises: creating a virtual storage system for storing a dataset, the virtual storage system including a virtual drive layer that includes a plurality of virtual drives for storing at least a portion of the dataset as block data; and a block storage backend layer for storing at least the portion of the dataset as block data, the block storage backend layer including one or more block-based storage devices; receiving an I/O operation with respect to the dataset; and based on the received I/O operation, storing, in the block storage backend layer, an update to the dataset.

Claims (29)

1. A method of providing block-based storage, the method comprising:

creating a virtual storage system including:

a virtual drive layer that includes a plurality of virtual drives, wherein one or more virtual drives of the plurality of virtual drives have associated local instance stores for storing data from one or more I/O operations related to one or more portions of a dataset as block data in block-based storage and wherein the plurality of virtual drives have a first I/O performance; and

a block storage backend layer provided by a cloud service provider, for storing at least a portion of the dataset as block data in block-based storage, the block storage backend layer including one or more block-based storage devices and wherein the one or more block-based storage devices of the block storage backend layer have a second I/O performance that is less than the first I/O performance;

receiving an I/O operation with respect to the dataset, including storing data for the received I/O operation in one or more of the plurality of virtual drives; and

based on the received I/O operation, storing, in the block storage backend layer, an update to the dataset as block storage-based data, wherein the update is generated at the virtual drive layer.

2. The method of claim 1 , wherein creating the virtual storage system further comprises configuring one or more of the plurality of virtual drives with virtual drive logic for managing processing of I/O operations in the virtual storage system.

3. The method of claim 1 , wherein the plurality of virtual drives include cloud computing instances with local storage.

4. The method of claim 1 , wherein creating the virtual storage system further comprises instantiating the one or more block-based storage devices as cloud-based solid state drives.

5. The method of claim 1 , wherein storing, in the block storage backend layer, the update to the dataset further comprises transferring, from the virtual drive layer to the block storage backend layer, the data for the received I/O operation.

6. A virtual storage system within a cloud computing environment, the virtual storage system including:

a virtual drive layer that includes a plurality of virtual drives, wherein one or more virtual drives of the plurality of virtual drives have associated local instance stores for storing data from one or more I/O operations related to one or more portions of a dataset as block data in block-based storage and wherein the plurality of virtual drives have a first I/O performance; and

a block storage backend layer provided by a cloud service provider, for storing at least a portion of the dataset as block data in block-based storage, the block storage backend layer including one or more block-based storage devices and wherein the one or more block-based storage devices of the block storage backend layer have a second I/O performance that is less than the first I/O performance;

wherein the one or more virtual drives are configured to:

receive an I/O operation with respect to the dataset, including storing data for the received I/O operation in one or more of the plurality of virtual drives; and

based on the received I/O operation, store, in the block storage backend layer, an update to the dataset as block storage-based data, wherein the update is generated at the virtual drive layer.

7. The virtual storage system of claim 6 , wherein the one or more virtual drives are configured with virtual drive logic for managing processing of I/O operations in the virtual storage system.

8. The virtual storage system of claim 6 , wherein the plurality of virtual drives include cloud computing instances with local storage.

9. The virtual storage system of claim 6 , wherein the one or more virtual drives are configured to instantiate the one or more block-based storage devices as cloud-based solid-state drives.

10. The virtual storage system of claim 6 , wherein the one or more virtual drives are configured to transfer, from the virtual drive layer to the block storage backend layer, the data for the received I/O operation.

11. A non-transitory computer readable storage medium storing instructions, which when executed, cause a processor to:

create a virtual storage system including:

a virtual drive layer that includes a plurality of virtual drives, wherein one or more virtual drives of the plurality of virtual drives have associated local instance stores for storing data from one or more I/O operations related to one or more portions of a dataset as block data in block-based storage and wherein the plurality of virtual drives have a first I/O performance; and

a block storage backend layer provided by a cloud service provider, for storing at least a portion of the dataset as block data in block-based storage, the block storage backend layer including one or more block-based storage devices and wherein the one or more block-based storage devices of the block storage backend layer have a second I/O performance that is less than the first I/O performance;

receive an I/O operation with respect to the dataset, including storing data for the received I/O operation in one or more of the plurality of virtual drives; and

based on the received I/O operation, store, in the block storage backend layer, an update to the dataset as block storage-based data, wherein the update is generated at the virtual drive layer.

12. The non-transitory computer readable storage medium of claim 11 , the processor further configured to configure one or more of the plurality of virtual drives with virtual drive logic for managing processing of I/O operations in the virtual storage system.

13. The non-transitory computer readable storage medium of claim 11 , the processor further configured to instantiate the one or more block-based storage devices as cloud-based solid state drives.

14. The non-transitory computer readable storage medium of claim 11 , the processor further configured to transfer, from the virtual drive layer to the block storage backend layer, the data for the received I/O operation.
