Abstract:
Systems and methods for optimizing storage system performance are disclosed. A method includes: determining an expected lifetime of each of at least one computing instance; determining a disk data extent evaluation period for each of the at least one computing instance based on the determined expected lifetime; determining an input/output (I/O) wait time threshold for each of the at least one computing instance; determining an I/O wait time of each of the at least one computing instance using the determined disk data extent evaluation period; and in response to the determined I/O wait time of one or more of the at least one computing instance exceeding the determined I/O wait time threshold of the computing instance, moving at least one data extent associated with the one or more computing instance exceeding the determined I/O wait time threshold from hard disk drive storage to solid state drive storage.
