PERFORMANCE-BASED SCALING AND MIGRATION IN VIRTUAL STORAGE SYSTEMS
Dynamic scaling of a virtual storage system, including: detecting, within one or more virtual components of the virtual storage system, a change in performance; determining, in response to the detected change in performance, a scaling response based on the virtual storage system meeting one or more target performance metrics; and scaling, based on one or more available virtual components of the virtual storage system, up or down such that performance of the virtual storage system is in accordance within the one or more target performance metrics.
1 . A method comprising:
detecting a change in performance of a virtual storage system; and
in response to detecting the change in performance of the virtual storage system, moving a quantity of virtual storage devices from a first set of virtual storage device servers to a second set of virtual storage device servers of the virtual storage system to satisfy one or more performance metrics.
2 . The method of claim 1 , detecting the change in performance further comprises:
detecting a change in an application demand for an application utilizing the virtual storage system.
3 . The method of claim 1 , detecting the change in performance further comprises:
collecting performance metrics or storage utilization metrics of the virtual storage system.
