Abstract
A dual bitmap solution can be beneficial for reducing full cache scans due to data overlap issues that occur using an overlap mechanism. One bitmap is geared towards random read workloads while the other bitmap is geared towards sequential read workloads. When a read command is received, the appropriate bitmap is checked to see if a full scan is necessary. Only if a relevant bit of the bitmap indicates that there is an overlap will the full scan occur. The relevant bit corresponds to the data for a corresponding read command. The bitmaps can be maintained in parallel or the data storage device can switch between maintaining either a bitmap directed to sequential read workloads or a bitmap directed to random read workloads.
