Managing of storage resources

A control entity adapted to manage a virtual storage volume in a cloud architecture with at least one host providing storage volume, the control entity comprising:

• processing circuitry;
• and
• memory containing instructions executable by the processing circuitry whereby the control entity is operative to:
• check a virtual storage volume for execution of a storage service request, wherein the checking is triggered by a request interface;
• cause the request interface to request additional storage volume directly from the at least one host if the storage service request cannot be executed by the virtual storage volume;
• and
• assign the additional storage volume to the virtual storage volume.

A request interface entity for managing a virtual storage volume in a cloud architecture with at least one host providing storage volume, the request interface entity comprising:

• processing circuitry;
• and
• memory containing instructions executable by the processing circuitry whereby the request interface entity is operative to:
• trigger a checking of a virtual storage volume to execute a storage service request;
• cause requesting of additional storage volume directly from the at least one host, if the outcome of the checking is that the storage service request cannot be fulfilled by the virtual storage volume;
• and
• cause assignment of the additional storage volume to the virtual storage volume.

A system, comprising:

• a request interface entity for managing a virtual storage volume in a cloud architecture with at least one host providing storage volume, wherein the request interface entity comprises:
• first processing circuitry;
• and
• first memory containing instructions executable by the first processing circuitry whereby the request interface entity is operative to:
• trigger a checking of a virtual storage volume to execute a storage service request;
• cause requesting of additional storage volume directly from the at least one host, if the outcome of the checking is that the storage service request cannot be fulfilled by the virtual storage volume;
• and
• cause assignment of the additional storage volume to the virtual storage volume;
• and
• a control entity configured to manage a virtual storage volume in a cloud architecture with at least one host providing storage volume, and configured to communicate with the request interface entity, wherein the control entity comprises:
• second processing circuitry;
• and
• second memory containing instructions executable by the second processing circuitry whereby the control entity is operative to:
• check a virtual storage volume for execution of a storage service request, wherein the checking is triggered by the request interface entity;
• cause the request interface entity to request additional storage volume directly from the at least one host if the storage service request cannot be executed by the virtual storage volume;
• and
• assign the additional storage volume to the virtual storage volume.
