Data storage resource allocation using blacklisting of data storage requests classified in the same category as a data storage request that is determined to fail if attempted
First Claim
1. A method for data storage resource allocation, the method comprising:
- classifying, by a server in a data management system, data storage requests into a plurality of categories,wherein a category of a respective data storage request is based on a storage policy comprising rules for allocating data storage resources for the respective data storage request, andwherein the data storage requests are in a queue of data storage requests to be performed in the data management system;
determining, by the server, based on one or more abbreviated checks, whether a first data storage request in the queue of data storage requests would fail if attempted, wherein the determining comprises;
(i) selecting, from a plurality of data storage resources required by the first data storage request, two or more data storage resources that are physical resources, and(ii) performing one or more physical checks of whether the selected two or more data storage resources are available for the first data storage request, in an order based on relative chances of failure of the respective selected two or more data storage resources and ahead of any logical checks of the selected two or more data storage resources,wherein the performing of the one or more physical checks includes determining whether hardware for performing the first data storage request is working; and
when the server determines that, based on the one or more abbreviated checks, the first data storage request would fail if attempted, updating the queue of data storage requests, by the server, to indicate that;
(a) the first data storage request and (b) one or more second data storage requests classified in the same category as the first data storage request should not be performed,wherein updating the queue occurs without checking whether the one or more second data storage requests would fail if attempted, andwherein updating the queue occurs without attempting to perform the first data storage request and the one or more second data storage requests.

Abstract
A resource allocation system begins with an ordered plan for matching requests to resources that is sorted by priority. The resource allocation system optimizes the plan by determining those requests in the plan that will fail if performed. The resource allocation system removes or defers the determined requests. In addition, when a request that is performed fails, the resource allocation system may remove requests that require similar resources from the plan. Moreover, when resources are released by a request, the resource allocation system may place the resources in a temporary holding area until the resource allocation returns to the top of the ordered plan so that lower priority requests that are lower in the plan do not take resources that are needed by waiting higher priority requests higher in the plan.

(a) the first data storage request and (b) one or more second data storage requests classified in the same category as the first data storage request should not be performed,wherein updating the queue occurs without checking whether the one or more second data storage requests would fail if attempted, and wherein updating the queue occurs without attempting to perform the first data storage request and the one or more second data storage requests. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A data management system for data storage resource allocation based on classifying data storage requests, the system comprising:
-
a server hosting a storage manager comprising a database, wherein the database comprises storage policies that govern how to allocate resources for data storage requests; and wherein the storage manager is configured to; maintain a queue of data storage requests to be performed in the data management system, classify data storage requests into a plurality of categories, wherein a category of a given data storage request is associated with a storage policy that governs how to allocate resources for the given data storage request, and determine based on one or more abbreviated checks, whether a first data storage request in the queue of data storage requests would fail if attempted, comprising; (i) selecting physical resources required by the first data storage request, and (ii) performing one or more checks of whether the selected physical resources are available for the first data storage request, including whether hardware for performing the first data storage request is working, in an order based on relative chances of failure of the respective selected physical resources and ahead of any logical checks of the selected physical resources; when the server determines, based on the one or more abbreviated checks, that the first data storage request would fail if attempted, updating the queue of data storage requests to indicate that;
(a) the first data storage request and (b) one or more second data storage requests classified in the same category as the first data storage request should not be performed,wherein the server updates the queue without checking whether the one or more second data storage requests would fail if attempted, and wherein the server updates the queue without attempting to perform the first data storage request and the one or more second data storage requests. - View Dependent Claims (9, 10, 11, 12, 13)
