Abstract

Locally providing cloud storage array services for a storage array of a data center when the storage array is not connected to a remote cloud-based storage array services provider includes initiating, by a primary storage array, one or more cloud storage array services and locally providing the cloud storage array services. Such local providing of the cloud storage array services also includes generating, by the cloud storage array services, metadata describing one or more real-time storage array characteristics and presenting the metadata to a user through a local area network.

3. The method of claim 2, wherein the data center further comprises a plurality of storage arrays, including the primary storage array and the method further comprises:

prior to detecting the loss of the data communications connection between the primary storage array and the remote, cloud-based storage array services provider;

periodically retrieving, by the primary storage array from the remote cloud-based storage array services provider, a current configuration of the cloud storage array services and the plurality of storage arrays.

4. The method of claim 1, wherein the data center further comprises a plurality of storage arrays, including the primary storage array, and generating, by the cloud storage array services, metadata describing one or more real-time storage array characteristics further comprises:

generating metadata describing one or more real-time storage array characteristics of each of the plurality of the storage arrays; and

aggregating, for presentation to the user, the metadata of each of the plurality of storage arrays.

5. The method of claim 1, wherein the data center further comprises a plurality of storage arrays, including the primary storage array, and initiating the one or more cloud storage array services further comprises:

selecting, by the primary storage array in dependence upon workload characteristics of each of the plurality of storage arrays, one of the plurality of storage arrays to host the one or more cloud storage array services.

6. The method of claim 5, further comprising:

detecting, by the primary storage array, a change in workload characteristics of each of the plurality of storage arrays; and

re-selecting one of the plurality of storage arrays to host the one or more cloud storage array services in dependence upon the changed workload characteristics.

7. The method of claim 5,further comprising:

operating, by the primary storage array, as a proxy for the selected storage array when the selected storage array is not the primary storage array; and

presenting the metadata to a user through a local area network further comprises presenting the metadata through the proxy of the primary storage array.

8. An apparatus for locally providing cloud storage array services for a storage array of a data center when the storage array is not connected to a remote cloud-based storage array services provider, the apparatus comprising a computer processor and a computer memory operatively coupled to the computer processor, where the computer memory includes computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:

initiating, by a primary storage array, one or more cloud storage array services; and

locally providing the cloud storage array services including;

generating, by the cloud storage array services, metadata describing one or more real-time storage array characteristics; and

presenting the metadata to a user through a local area network.

9. The apparatus of claim 8, further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:

detecting, by the primary storage array prior to initiating the cloud storage array services by the primary storage array, a data communications connection between the primary storage array and a remote cloud-based storage array services provider, wherein the remote cloud-based storage array services provider provides the one or more cloud storage array services; and

detecting, by the primary storage array, loss of the data communications connection between the primary storage array and the remote cloud-based storage array services provider, wherein;

initiating the one or more cloud storage array services by the primary storage array further comprises initiating the one or more cloud storage array services by the primary storage array only in response to detecting the loss of the data communications connection between the primary storage array and the remote, cloud-based storage array services provider.

10. The apparatus of claim 9, wherein the data center further comprises a plurality of storage arrays, including the primary storage array and the apparatus further comprises computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:
