Abstract: Embodiments of the present disclosure are directed towards a computer system with cache policy that may be modified in response to temperature changes. In some embodiments, the system may include a memory storage having a first storage device with a first response time, and a second storage device with a second response time that may be higher than the first response time. The system may include a cache policy module to facilitate execution of I/O requests to access the memory storage. The cache policy module may be configured to restrict access to at least a portion of the first storage device and provide access to the second storage device, in response to an increase of temperature of the first storage device above a threshold. Other embodiments may be described and/or claimed.
