Abstract:
1. A computer implemented method for booting an operating system from a virtual hard disk, the computer implemented method comprising: forming, by a memory partition manager unit, a first partitioned memory segment within a random access memory by a preconfigured amount, wherein the random access memory receives power from an integrated uninterruptible power supply, and wherein the memory partition manager unit is separate from the random access memory; loading, by the memory partition manager unit, a boot application into the first partitioned memory segment of the random access memory to form the virtual hard disk; receiving an input to boot the operating system; responsive to receiving the input to boot the operating system, determining if the virtual hard disk of the random access memory contains the operating system; responsive to determining that the virtual hard disk of the random access memory contains the operating system, booting the operating system from the virtual hard disk; determining, by the memory partition manager unit, whether an energy level of the integrated uninterruptible power supply is below a threshold; responsive to determining that the energy level of the integrated uninterruptible power supply is below the threshold, sending, by the memory partition manager unit, an alert predicting a failure of the virtual hard disk; and signaling, by the memory partition manager unit, the operating system that the failure of the virtual hard disk is imminent.
