Abstract:
1. An information system comprising: a storage system including a controller in communication with a plurality of storage devices, said plurality of storage devices being divided into at least a first group and a second group, wherein there are a plurality of said first groups and a plurality of said second groups; a plurality of first temperature sensors, each of which senses a first temperature condition for the first group; and a plurality of second temperature sensors, each of which senses a second temperature condition for the second group, wherein a heat distribution rule designates said first groups to be high temperature groups and said second groups to be low temperature groups, wherein the heat distribution rule is implemented by migrating data with higher load of input/output (I/O) operations to the high temperature groups than to the low temperature groups so that said plurality of first temperature sensors maintain a higher temperature than said plurality of second temperature sensors.
