Storage resource pack management
Methods, apparatus and computer program products implement embodiments of the present invention that include identifying, by a first computer in communication with a storage system having one or more storage devices, storage resources on the storage system, and defining multiple resource packs, each of the resource packs comprising respective multiple attributes for the storage resources. In response to an inventory request from a second computer in communication with the first computer, each of the resource packs can be conveyed to the second computer. Additionally, upon receiving, from the second computer, an allocation request to allocate a portion of a given resource pack, the portion of the given resource pack can be allocated in response to the request.
1. A method, comprising:
identifying, by ha first computer locally and internally and in communication with a storage system having one or more storage devices, storage resources on the storage system;
receiving, by the first computer from a second computer located externally to the storage system, a resource pack inventory request;
defining multiple available resource packs based on the resource pack inventory request, each of the available resource packs comprising respective multiple attributes for the storage resources;
conveying each of the available resource packs to the second computer in communication with the first computer;
receiving, by the first computer, a request from the second computer to allocate portion of the available resource pack;
allocating, by the first computer, the portion of the available resource pack to the second computer;
maintaining, by the second computer, mapping information for storage resources on the storage system, and updating the mapping information upon allocating the portion of the available resource pack; and
receiving, from the second computer and to the first computer, a request to free an allocated portion of the available resource pack, and reclaiming, by the first computer, the allocated portion in the available resource pack.
2. The method according to claim 1 , wherein the attributes are selected from a list consisting of storage identification attributes, storage configuration attributes, cost attributes and credentials parameters.
3. A storage facility, comprising:
a storage system having one or more storage devices; and
a first computer in communication with the storage system, and configured:
to identify, locally and internally, storage resources on the storage system,
to receive, by the first computer from a second computer located externally to the storage system, a resource pack inventory request;
to define multiple available resource packs based on the resource pack inventory request, each of the available resource packs comprising respective multiple attributes for the storage resources,
to convey each of the available resource packs to the second computer in communication with the first computer,
to receive, by the first computer, a request from the second computer to allocate portion of the available resource pack;
to allocate, by the first computer, the portion of the available resource pack to the second computer;
to maintain, by the second computer, mapping information for storage resources on the storage system, and updating the mapping information upon allocating the portion of the available resource pack; and
to receive, from the second computer and to the first computer, a request to free an allocated portion of the available resource pack, and reclaiming, by the first computer the allocated portion in the available resource pack.
4. The storage facility according to claim 3 , wherein the attributes are selected from a list consisting of storage identification attributes, storage configuration attributes, cost attributes and credentials parameters.
5. A computer program product, the computer program product comprising:
a non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:
computer readable program code executing on a first computer in communication with a storage system having one or more storage devices configured to identify, locally and internally, storage resources on the storage system;
computer readable program code configured to receive, by the first computer from a second computer located externally to the storage system, a resource pack inventory request;
computer readable program code configured to define multiple available resource packs based on the resource pack inventory request, each of the available resource packs comprising respective multiple attributes for the storage resources;
computer readable program code configured to convey each of the available resource packs to the second computer in communication with the first computer;
computer readable program code configured to receive, by the first computer, a request from the second computer to allocate portion of the available resource pack;
computer readable program code configured to allocate, by the first computer, the portion of the available resource pack to the second computer;
computer readable program code configured to maintain, by the second computer, mapping information for storage resources on the storage system, and updating the mapping information upon allocating the portion of the available resource pack; and
computer readable program code configured to receive, from the second computer and to the first computer, a request to free an allocated portion of the available resource pack, and to reclaim, by the first computer, the allocated portion in the available resource pack.
6. The computer program product according to claim 5 , wherein the attributes are selected from a list consisting of storage identification attributes, storage configuration attributes, cost attributes and credentials parameters.
