Abstract

A storage array for providing data storage services includes persistent storage that stores approved preferences and a storage array manager that obtains event-response preferences for hosts receiving the data storage services; predicts, based on the event-response preferences, a set of additional event-response preferences for a host of the hosts; predicts an additional event-response preference for a host of the hosts based on a request associated with a second host of the hosts; generates a heat map for the host based on: the event-response preferences, the set of additional event-response preferences, the additional event-response preference, and global event-response preferences that associate events with responses for all of the hosts; identifies a final set of event-response preferences for the host using the heat map; updates the approved preferences based on the final set of event-response preferences; and provides unsolicited data to the host based on the updated approved preferences.

First claim

What is claimed is:

1. A storage array for providing data storage services, comprising:
persistent storage for storing approved preferences; and
a storage array manager programmed to:
obtain event-response preferences for hosts receiving the data storage services;
predict, based on the event-response preferences, a set of additional event-response preferences for a host of the hosts;
predict an additional event-response preference for a host of the hosts based on a request associated with a second host of the hosts;
generate a heat map for the host based on:
the event-response preferences,
the set of additional event-response preferences,
the additional event-response preference, and
global event-response preferences that associate events with responses for all of the hosts;

obtain host input, using the heat map, to identify a final set of event-response preferences for the host;
update the approved preferences based on the final set of event-response preferences for the host to obtain updated approved preferences; and
provide unsolicited data to the host based on the updated approved preferences.

2. The storage array of claim 1 , wherein predicting, based on the event-response preferences, a set of additional event-response preferences for a host of the hosts comprises:
matching the event-response preferences for hosts to second event-response preferences for a third host of the hosts; and
adding an event-response preference of the second event-response preferences that is not included in the event-response preferences to the set of additional event-response preferences for the host of the hosts.

3. The storage array of claim 1 , wherein the event-response preferences comprises:
an event-response preference that specifies a response that the storage array should perform when the storage array identifies an event corresponding to the response.

4. The storage array of claim 3 , wherein the response is a type of information to be provided to the host.

5. The storage array of claim 3 , wherein the event is a request for a type of information from a different host of the hosts received by the storage array.

6. The storage array of claim 1 , wherein the unsolicited data is also provided to a second host of the hosts.

7. The storage array of claim 6 , wherein the unsolicited data is provided to the host in response to an occurrence of an event that the updated approved preferences associates with a response for the host that requires that the host be provided with the unsolicited data.

8. The storage array of claim 1 , wherein obtaining the host input, using the heat map, to identify the final set of event-response preferences for the host comprises:
determining that the host input indicates that one of the set of additional event-response preferences for the host is not to be included in the final set of event-response preferences for the host; and
based on the determination, not including the one of the set of additional event-response preferences for the host in the final set of event-response preferences for the host.

9. The storage array of claim 1 , wherein obtaining the host input, using the heat map, to identify the final set of event-response preferences for the host comprises:
determining that the host input indicates that an event-response preference of the global event-response preferences is not to be included in the final set of event-response preferences for the host; and
based on the determination, not including the event-response preference of the global event-response preferences in the final set of event-response preferences for the host.

10. The storage array of claim 1 , wherein the unsolicited data comprises a portion of data stored in the persistent storage as part of providing the data storage services.

11. A method for providing data storage services, comprising:
obtaining event-response preferences for hosts receiving the data storage services;
predicting, based on the event-response preferences, a set of additional event-response preferences for a host of the hosts;
predicting an additional event-response preference for a host of the hosts based on a request associated with a second host of the hosts;
generating a heat map for the host based on:
the event-response preferences,
the set of additional event-response preferences,
the additional event-response preference, and
global event-response preferences that associate events with responses for all of the hosts;

obtaining host input, using the heat map, to identify a final set of event-response preferences for the host;
updating approved preferences based on the final set of event-response preferences for the host to obtain updated approved preferences; and
providing unsolicited data to the host based on the updated approved preferences.

12. The method of claim 11 , wherein predicting, based on the event-response preferences, a set of additional event-response preferences for a host of the hosts comprises:
matching the event-response preferences for hosts to second event-response preferences for a third host of the hosts; and
adding an event-response preference of the second event-response preferences that is not included in the event-response preferences to the set of additional event-response preferences for the host of the hosts.

13. The method of claim 11 , wherein the event-response preferences comprises:
an event-response preference that specifies a response that a storage array providing the data storage services should perform when the storage array identifies an event corresponding to the response.

14. The method of claim 13 , wherein the response is a type of information to be provided to the host.

15. The method of claim 13 , wherein the event is a request for a type of information from a different host of the hosts received by the storage array.

16. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for providing data storage services, the method comprising:
obtaining event-response preferences for hosts receiving the data storage services;
predicting, based on the event-response preferences, a set of additional event-response preferences for a host of the hosts;
predicting an additional event-response preference for a host of the hosts based on a request associated with a second host of the hosts;
generating a heat map for the host based on:
the event-response preferences,
the set of additional event-response preferences,
the additional event-response preference, and
global event-response preferences that associate events with responses for all of the hosts;

obtaining host input, using the heat map, to identify a final set of event-response preferences for the host;
updating approved preferences based on the final set of event-response preferences for the host to obtain updated approved preferences; and
providing unsolicited data to the host based on the updated approved preferences.

17. The non-transitory computer readable medium of claim 16 , wherein predicting, based on the event-response preferences, a set of additional event-response preferences for a host of the hosts comprises:
matching the event-response preferences for hosts to second event-response preferences for a third host of the hosts; and
adding an event-response preference of the second event-response preferences that is not included in the event-response preferences to the set of additional event-response preferences for the
