Abstract
A method of attribute based resource allocation is presented. A resource such as a pool of storage has certain properties or attributes associated with portions of the pool. When a request for storage is needed, the requester provides a selection expression which comprises properties and logical operators. From the selection expression a determination is made to allocate portions of the storage pool which meet the requirements of the selection expression.
Claims17
A computer-implemented method of creating a data storage pool, comprising:
- providing information for a plurality of storage resources in response to a user query;
- assigning, in a computer having a processor, at least one storage property to selected ones of the plurality of storage resources in response to user instructions to define the data storage pool;
- receiving a logical expression to identify respective ones of the storage resources that are available for a requested store operation based upon the storage properties assigned to the selected ones of the storage resources;
- determining which ones of the identified storage resources have preferred characteristics;
- allocating selected ones of the identified storage resources for the requested store operation;
- receiving, prior to the step of allocating selected ones of the identified storage resources, a new storage property for the logical expression if a desired storage property is not present in the assigned storage properties,
- wherein the logical expression includes a storage property not assigned to any of the storage resources, and further including:
- receiving an identification of a first one of the plurality of storage resources having the unassigned storage property;
- and
- allocating the first one of the storage resources based upon the logical expression.

An article, comprising:
- a computer readable storage medium having stored thereon instructions that when executed by a computer result in the following:
- providing information for a plurality of storage resources in response to a user query;
- assigning at least one storage property to selected ones of the plurality of storage resources in response to user instructions to define the data storage pool;
- receiving a logical expression to identify respective ones of the storage resources that are available for a requested store operation based upon the storage properties assigned to the selected ones of the storage resources;
- determining which ones of the identified storage resources have preferred characteristics;
- allocating selected ones of the identified storage resources for the requested store operation;
- and
- receiving, prior to the step of allocating selected ones of the identified storage resources, a new storage property for the logical expression if a desired storage property is not present in the assigned storage properties, wherein the logical expression includes a storage property not assigned to any of the storage resources, and further including:
- receiving an identification of a first one of the plurality of storage resources having the unassigned storage property;
- and
- allocating the first one of the storage resources based upon the logical expression.

A system, comprising:
- a processor;
- and
- a memory coupled to the processor, the memory including instructions that when executed result in the following:
- providing information for a plurality of storage resources in response to a user query;
- assigning at least one storage property to selected ones of the plurality of storage resources in response to user instructions to define the data storage pool;
- receiving a logical expression to identify respective ones of the storage resources that are available for a requested store operation based upon the storage properties assigned to the selected ones of the storage resources;
- determining which ones of the identified storage resources have preferred characteristics:
- allocating selected ones of the identified storage resources for the requested store operation;
- and
- receiving, prior to the step of allocating selected ones of the identified storage resources, a new storage property for the logical expression if a desired storage property is not present in the assigned storage properties, wherein the logical expression includes a storage property not assigned to any of the storage resources, and further including:
- receiving an identification of a first one of the plurality of storage resources having the unassigned storage property;
- and
- allocating the first one of the storage resources based upon the logical expression.
