Abstract: Certain aspects of the present disclosure relates to a system having a virtual desktop server (VDS). In operation, the VDS is configured to: create a random access memory (RAM) disk in a memory; partition the RAM disk into a two partitions, one for caching first data received from instances of pooled virtual machines (VMs), and the other for caching second data received from personalized VMs; create a data store in a storage device, including two portions for preserving the first data and the second data respectively; and perform a plurality of data write through operations based on VM types. The write through cache operations may include: disabling data write through for the first data; and enabling the data write through for the second data.

Abstract: Certain aspects of the present disclosure relates to a system having a virtual desktop server (VDS), which may be electrically powered by an electric power supply and an uninterruptable power supply (UPS). The VDS has a processor, a memory, and a storage device storing computer executable code. When executed at processor, the computer executable code is configured to: allocate a portion of storage device to create a data store, allocate a portion of memory to create a random access memory (RAM) disk, detect power status of the VDS, and perform write through cache operations based on the detected power status. In certain embodiments, the write through cache operations include: disabling data write through from RAM disk to data store, when VDS is powered by the EPS and the UPS; and enabling data write through from RAM disk to data store when VDS is electrically powered by UPS only.

Abstract: The present disclosure relates to a predicative power management system configured to adjust computer CPU clock rate by a computer user to conserve energy based on user category. In certain embodiments, the predicative power management system includes (a) a computer user profile creator module, and (b) a power management module. The computer user profile creator module is used to create computer usage profiles and each of the computer usage profiles has a profileID for a computer user with a computer userID. The power management module is used to set and adjust computer CPU clock rate, CPU voltage and device states based on computer users' category and the computer user's computer usage profile.
