8. Note Refer to the SAS Interface Manual for more detail concerning the cache bits Of the 16 Mbytes physical buffer space in the drive approximately 13 000 kbytes can be used as a cache The buffer is divided into logical segments from which data is read and to which data is written The drive keeps track of the logical block addresses of the data stored in each segment of the buffer If the cache is enabled see RCD bit in the SAS Interface Manual data requested by the host with a read command is retrieved from the buffer if possible before any disc access is initiated If cache operation is not enabled the buffer is still used but only as circular buffer segments during disc medium read operations disregarding Prefetch operation for the moment That is the drive does not check in the buffer segments for the requested read data but goes directly to the medium to retrieve it The retrieved data merely passes through some buffer segment on the way to the host All data transfers to the host are in accordance with buffer full ratio rules See the explanation provided with the information about Mode Page 02h disconnect reconnect control in the SAS Interface Manual The following is a simplified description of the prefetch cache operation Case A read command is received and all of the requested logical blocks are already in the cache 1 Drive transfers the requested logical blocks to the initiator Case B A Read command requests data
