Abstract
A system and method for allocating storage devices within a database system including fast solid state storage devices (SSDs) and traditional hard drive storage device (HDDs). The method repetitively collects temperature and queue depth data for each storage device, and determines from the collected data points a service time for each storage device. The method then selects, in response to an allocation request, a storage device having a minimum total wait time determined from the current queue depth and service time for each storage device.
