Abstract
A method and apparatus for increasing disk drive performance in a disk drive system are described. Embodiments of the present invention provide a method including the steps of providing a disk drive and a nonvolatile memory (NVM) as an integral part of the disk drive. Particular data can be selected and stored in the NVM. Such data can be file system or database metadata for example. According to the method and system disclosed herein, the present invention increases the speeds at which data is written and read to magnetic media. Drive performance is achieved while maintaining reliability.
Claims14
A method for increasing performance in a direct access storage device (DASD) system, the method comprising the steps of:
- (a) providing a disk drive;
- (b) providing a nonvolatile memory (NVM) as an integral part of the disk drive;
- (c) selecting performance critical data to be stored in the NVM;
- and
- (d) storing the performance critical data in the NVM to improve the performance of the DASD system.
A computer-readable medium including a program for increasing performance in a direct access storage device (DASD) system, the DASD system having a disk drive and a nonvolatile memory (NVM) as an integral part of the disk drive, the programing comprising instructions for:
- recognizing the presence of the NVM;
- selecting data to be stored in the NVM;
- and
- storing data in the NVM.
A system for increasing performance in a direct access storage device (DASD) system, the system comprising:
- a disk drive;
- a nonvolatile memory (NVM) as an integral part of the disk drive;
- and
- a disk drive controller programmed to recognize the NVM an integral part of the disk drive, wherein the disk drive controller selects performance critical data to be stored in the NVM and stores the performance critical data in the NVM to improve the performance of the DASD system
