Abstract:
1. A computer program product comprising a computer recordable medium having a computer readable program recorded thereon, wherein the computer readable program, when executed on a computing device, causes the computing device to: charge a super capacitor to a first voltage level by setting a voltage regulator output to the first voltage level, wherein the voltage regulator provides power to a memory system; set the voltage regulator output to a second voltage level such that the memory system continues to operate at the second voltage level; monitor and record voltage and current discharge values at the super capacitor at regular intervals until a test period expires; calculate a capacitance of the super capacitor based on the recorded voltage and current discharge values; and determine whether the capacitance of the super capacitor will support hardening of cache data from a volatile memory to a non-volatile memory in the memory system in response to a power event.
