Abstract
A method includes monitoring a number of read access requests to an address for data stored on a backing store. The method also includes comparing the number of read access requests to a read access threshold. The read access threshold includes a threshold number of read access requests for the address. The method also includes caching data corresponding to a write access request to the address in response to determining that the number of read access requests satisfies the read access threshold.
Claims20
A method, comprising:
- monitoring a number of read access requests to an address for data stored on a backing store;
- comparing the number of read access requests to a read access threshold, wherein the read access threshold comprises a threshold number of read access requests for the address;
- and
- caching data corresponding to a write access request to the address in response to determining that the number of read access requests satisfies the read access threshold.
1 more element
An apparatus, comprising:
- a memory device configured to cache data corresponding to data on a non-volatile storage device;
- and
- a storage manager configured to:
- receive a write operation to write data on the non-volatile storage device, the write data associated with a set of addresses;
- and
- caching the write data to the memory device in response to determining that a number of read counts for the set of addresses satisfies a read threshold.
3 more elements
A system, comprising:
- means for writing data to a set of addresses;
- means for calculating a threshold number of read access requests for the set of addresses;
- means for storing a number of read access requests for the set of addresses;
- and
- means for caching data being written to the set of addresses in response to determining that the number of read access requests for the set of addresses satisfies the threshold number of read access requests.
