摘要 |
Various embodiments for optimized power savings in a storage virtualization system are provided. First meta data for physical resources which describes a power status of a storage resource in one of a powered-on/read-write, powered-on/read only, and powered-off power state is created. Second meta data for each of the physical storage resources which determines an actual performance of the physical storage resources and which supports optimization of a powering-on and a powering-off of the physical storage resources is created. A write request from one of a host and application to logical and virtual storage resource is executed. |
