Abstract
A system allows one or more hybrid hard disks or any other storage devices to share a logical nonvolatile device formed by one or more non-volatile memory devices. The system comprises a control logic to reserve on a hybrid hard disk a space that corresponds to a non-volatile memory device in the hybrid hard disk and to use a space access instruction to access the non-volatile memory device. The control logic accesses the logical non-volatile memory device in an event that a content of a storage device is stored in the logical non-volatile memory device in response to an instruction to access the storage device.
Claims15
A system, comprising:
- a processor;
- a first storage device that comprises a first hard disk and a first non-volatile memory device;
- a second non-volatile memory device;
- a second storage device, wherein the second non-volatile memory device is provided on the second storage device that comprises a second hybrid hard disk;
- a control logic that couples to the processor to control the first non-volatile memory device and the second non-volatile memory device to form a logical non-volatile memory device, to convert data from at least one of the first hard disk and the second storage device into logical data and to store the logical data in the logical non-volatile memory device, the control logic controls to share the logical non-volatile memory device among the first storage device and the second storage device.
A method, comprising:
- providing a first hybrid storage device that comprises a first hard disk and a first non-volatile memory device;
- providing a second hybrid storage device that comprises a second hard disk and a second non-volatile memory device;
- forming the first non-volatile memory device and the second non-volatile memory device to a logical non-volatile memory device to store logical data that is converted from data of at least one of the first hard disk and the second hard disk into logical data.
A machine readable storage medium comprising a plurality of instructions that in response to being executed result in a computing device
- providing a first hybrid storage device that comprises a first hard disk and a first non-volatile memory device;
- providing a second hybrid storage device that comprises a second hard disk and a second non-volatile memory device;
- forming the first non-volatile memory device and the second non-volatile memory device to a logical non-volatile memory device to store logical data that is converted from data of at least one of the first hard disk and the second hard disk into logical data.
