Briefly, in accordance with an embodiment of the invention, a system and method to alter a cache policy of the system in response to the system transitioning from a first power state to a second power state is provided. The system may include a non-volatile disk cache and a disk memory, wherein the cache policy is used by the non-volatile disk cache to cache information for the disk memory.

A temperature sensitive memory, such as a ferro-electric polymer memory, may be utilized as a disk cache memory in one embodiment. If the temperature begins to threaten shutdown, the memory may be transitioned from a write-back to a write-through cache memory. In such case, the system is ready for shutdown without the loss of critical data.

Method and system to spin up a hard disk prior to a data exchange request. In one embodiment, the occurrence of a predetermined event is detected. In response, the hard disk is activated prior to a request to exchange data with the hard disk. In one embodiment, the predetermined event is a cacche of the hard disk reaching a predetermined level of dirty data, the predetermined level being less than completely full. In an alternative embodiment, the predetermined event includes detecting a presence of a computer user.

Methods and apparatus relating to accessing snapshot data image of a data mirroring volume are described. In one embodiment, a host computer is allowed to access a first data volume and a second data volume. The second data volume may comprise data corresponding to a snapshot image of the first data volume prior to a suspension of data mirroring. Other embodiments are also disclosed.
摘要:
Disclosed herein are methods that may be implemented in a mobile computer system. An exemplary method may include initiating a split of a storage volume of the mobile computer system. The storage volume may comply with a fault tolerant storage technology. Suitable technologies include, but are not limited to, those based on Redundant Array of Independent (or Inexpensive) Disks (RAID). In one aspect, the initiation of the split of the storage volume may be based, at least in part, on power availability. Then, a reduction of a power consuming state of a first storage device of the volume may be initiated.

Methods and apparatus relating to automated intermittent data mirroring volumes are described. In one embodiment, data mirroring may be suspended in response to occurrence of a scheduled or predefined event. Other embodiments are also disclosed.
摘要:
A method and system to adjust a non-volatile cache associativity are described. In one embodiment, the method and system include determining a status of the system; and setting an associativity level of the non-volatile memory cache (NVC) of the system, based on that status of the system. In one embodiment, the non-volatile memory unit is a cache of the hard drive. Furthermore, in one embodiment, determining the status of the system includes determining whether the system is a mobile computer, and if so, determining whether the system is receiving power from a battery source or AC power from a wall outlet.
