System and method for improving cache performance |
摘要 |
A method, computer program product, and computing system for receiving a read request on a first cache system, wherein the read request identifies previously-written content included within a data array. The previously-written content identified in the read request is obtained from the data array. A read request content identifier is generated for the previously-written content identified in the read request. The read request content identifier associated with the previously-written content identified in the read request is compared to a plurality of content identifiers included within a content directory for the first cache system to determine if a matching content identifier exists. Each of the plurality of content identifiers is associated with a piece of previously-written content included within the first cache system. |

1. A computer-implemented method of processing read requests comprising:
receiving a read request on a first cache system, wherein the read request identifies previously-written content included within a data array; obtaining the previously-written content identified in the read request from the data array; generating a read request content identifier for the previously-written content identified in the read request; comparing the read request content identifier associated with the previously-written content identified in the read request to a plurality of content identifiers included within a content directory for the first cache system to determine if a matching content identifier exists, wherein each of the plurality of content identifiers is associated with a piece of previously-written content included within the first cache system; and deleting at least one redundant copy of the previously-written content. |
