5.1 Mode Parameters

This parameter can be changed though the HDD disregards the specification of this field. The HDD divided the Cache Segments according to the inherent algorithm. That is, the Cache Segment size is best tuned per the request data size of Host command. Within one Cache Segment, data for various commands are stored.

q.Non cache segment size

If this field is greater than zero, this field advises the device server how many bytes the application client requests that the device server allocate for a buffer function when all other cache segments are occupied by data to be retained. If the number is at least one, caching functions in the other segments need not be impacted by cache misses to perform the buffer function. The impact of this field equals 0 or the sum of this field plus this field greater than the buffer size is vendor-specific.

This bit is not supported for the HDD. The HDD disregards the specification in this bit.
