Method and apparatus for improving resource utilization efficiency in a data center

摘要

A method of managing use of resources in data center 1100 comprises: determining whether first storage subsystem 1400 includes a virtual volume 1850 or a storage pool 1860 that uses a physical volume 1870 of second storage subsystem 1400 and, if yes, migrating the physical volume 1870 to first storage subsystem 1400; determining whether any storage subsystem 1400 includes a virtual volume 1850 created directly from a physical volume 1870 and, if yes, migrating the virtual volume 1850 to another virtual volume 1850 provisioned from the storage pool 1860 of the storage subsystem 1400; and determining whether all virtual volumes 1850 satisfy a preset service level objective and, if no, then selecting a virtual machine 1810 which has a smallest virtual machine disk file and selecting a storage pool 1860 having a largest free space, and then selecting a virtual volume 1850 of the storage subsystem 1400 which has the selected storage pool 1860 and migrating the virtual machine disk file of the selected virtual machine 1810 to the selected virtual volume 1850.
