Abstract
A computer system (a method) for providing storage management solution that enables server virtualization in data centers is disclosed. The system comprises a plurality of storage devices for storing data and a plurality of storage management drivers configured to provide an abstraction of the plurality of the storage devices to one or more virtual machines of the data center. A storage management driver is configured to represent a live disk or a snapshot of a live disk in a virtual disk image to the virtual machine associated with the driver. The driver is further configured to translate a logical address for a data block to one or more physical addresses of the data block through the virtual disk image. The system further comprises a master server configured to manage the abstraction of the plurality of the storage devices and to allocate storage space to one or more virtual disk images.
