摘要： Systems and methods for reducing problems and disadvantages associated with traditional approaches to encryption and decryption of data are provided. An information handling system may include a processor, a memory communicatively coupled to the processor, and a computer-readable medium communicatively coupled to the processor. The computer-readable medium may have instructions stored thereon, the instructions configured to, when executed by the processor: (i) periodically store, during an encryption or decryption operation performed on the computer-readable medium, one or more variables indicative of an encryption status of a volume of the computer-readable medium; (ii) determine, based on the one or more variables, whether the volume is in a partially encrypted or decrypted state; and (iii) in response to a determination that the volume is in a partially encrypted or decrypted state, boot from the volume and continue the encryption or decryption operation.

摘要： An client hosted virtualization system includes an authentication device, a processor and non-volatile memory with BIOS code and virtualization manager code. The virtualization manager initializes the client hosted virtualization system authenticates a virtual machine image, launches a portion of the virtual machine that initiates an authentication session with the authentication device, receives an authentication object from the authentication device, sends the authentication object to the portion of the virtual machine, and launches another portion of the virtual machine. The client hosted virtualization system is configurable to execute the BIOS or the virtualization manager.

摘要： A storage power optimized server system includes a high performance spinning hard drive for storing a first set of data and a power controlled hard drive for storing a second set of data. The high performance spinning hard drive is continuously driven while the power controlled hard drive may have a lower power consumption, slower access time or higher capacity than the high performance spinning hard drive. The first and second set of data may be based on one or more data conditions. The first set of data may include data that has been requested at a rate above a predetermined threshold, or after a predetermined file age date, or after a predetermined last access date. The second set of data may include data that has been requested at a rate below the predetermined request rate threshold, or before a predetermined file age, or before a predetermined last access date.

摘要： Generally described, embodiments of the present invention are directed at reducing the power consumed by a CPU. In accordance with one embodiment, a method is provided that transitions the CPU into a reduced power state in response to a fetch operation being dispatched to an I/O device. More specifically, the method includes comparing the latency associated with recovering from a reduced power state with the time remaining before a timer expires. Then, a signal is generated that identifies a timer-specific reduced power state. The method aggregates signals received from different timers to identify a reduced power that is appropriate given all of the processing that is scheduled to be performed.

摘要： A clock control technique allows reducing the power consumption of devices connected to a computer bus. Individual idle devices can be disconnected from the bus clock by a device clock controller and placed in a low-power state without waiting for all devices on the bus to go idle. When individual devices are idle, transactions on the bus are monitored and unclaimed transactions are claimed by the device clock controller, which then forces a retry of the transaction and reconnects the clock to the idle devices. This brings these devices from the low-power state to a full power state, where they are capable of claiming the transaction when it is retried.

摘要： A computer which has an ACPI compliant PCI-to-PCI bridge allows additional devices to be inserted, and allows existing devices to be removed or relocated without restarting the computer. A first PCI bus serves as a local bus, allowing a number of devices, including a PCI-to-PCI bridge, to be connected to the processor of a computer system. The first PCI bus also provides power and a clock signal to the PCI-to-PCI bridge and to various other PCI devices located in slots on the bus. The voltage level of the supplied power is controlled by software running on the processor. based on information obtained from the devices during power-up. The PCI-to-PCI bridge allows expansion by coupling a second PCI bus to the first PCI bus, via the PCI-to-PCI bridge. The second PCI bus includes a number of PCI slots, one of which is coupled to the PCI-to-PCI bridge and receives clock and power signals from the PCI-to-PCI bridge. Other devices may be connected to the second PCI bus by inserting the additional devices into slots in the second PCI bus. Additional PCI buses may be connected to the first and second PCI buses by inserting additional PCI-to-PCI bridges into slots in the PCI buses. Only one PCI bridge subsystem need be disabled, i.e. the one to which the new device is to be added or from which a preexisting device is to be removed.

摘要： A hard drive which prevents data access operations on the hard drive upon power up until the user enters a password. When the computer system is powered up, the hard drive spins up and is tested, responding only to a limited set of commands that do not permit data storage or retrieval operations. The password is located on the hard disk itself to prevent bypassing the hard drive's security using a new computer environment. When the user enters the correct password, the hard drive unlocks and operates as a conventional hard drive. If the user chooses, the hard drive may be unlocked by either of two passwords, one defined by the user and the other by the manufacturer. To obtain access to data areas during a locked state, a wipe data command is provided which overwrites all user data on the drive and unlocks the drive.
