Methods, apparatus and computer program products implement embodiments of the present invention that include storing one or more data volumes to a small computer system interface storage device, and receiving a request to map a given data volume to a host computer. One or more attributes of the given data volume are identified, and using the identified one or more attributes, a unique logical unit number (LUN) for the given data volume is generated. The given data volume is mapped to the host computer via the unique LUN. In some embodiments, the generated LUN includes one of the one or more attributes. In additional embodiments, the generated LUN includes a result of a hash function using the one or more attributes. In storage virtualization environments, the data volume may include secondary logical units, and mapping the given data volume to the host may include binding the SLU to the host.

Using deterministic logical unit numbers to dynamically map data volumes

Methods, apparatus and computer program products implement embodiments of the present invention that include receiving, by a first computer in communication with a storage system, multiple resource packs, each of the resource packs including a plurality of attributes for storage resources on the storage system. Upon the first computer receiving a request from a second computer for a storage service, one or more of the received resource packs are identified that have respective attributes matching the storage service, a given identified resource pack is selected and the given identified resource pack is conveyed to the second computer. In some embodiments, the given identified resource pack can be conveyed by conveying an allocation request to the storage system for a portion of the given identified resource pack, and in response to the request, the storage system can allocate the requested portion of the given identified resource pack to the second computer.

Matching storage resource packs to storage services

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.
