READ AHEAD BUFFER PROCESSING

摘要

Read data blocks based on a read-amount multiplied by an increment-amount from data storage and write the data blocks to the read-ahead buffer. If the total number of data blocks written to the read-ahead buffer is greater than or equal to the request-amount, then returning to the host the total number of data blocks written to the read-ahead buffer. If the total the number of data blocks written to the read-ahead buffer is less than the request-amount, repeating incrementing the increment-amount and reading data blocks equal to the read-amount multiplied by the increment-amount from the data storage, and writing the read data blocks to the read-ahead buffer until the total number of data blocks written to the read-ahead buffer is greater than or equal to the request-amount.
