摘要：A method for assigning data in a plurality of physical storage resources for aninformation handling system is disclosed. The plurality of physical storage resourcesincludes a first tier and a second tier with a lower performance and cost relative to

capacity than the first tier. A tier manager hosted on the information handling system andin electronic communication with the plurality of physical storage resources is configuredto: determine a seek distance value, operation rate, operation size value, and elapsedtime value for each page; and calculate a relative randomness value for each page usingthe seek distance value, operation rate, operation size value, and elapsed time valuedetermined for each page. A classification module may assign a physical location for eachpage such that the relative randomness value for each page in the first tier is greaterthan the relative randomness value for each page in the second tier.
