Minimum Pre-fetch specifies the minimum number of LBA's that the drive should read ahead after each
read command. A value of zero indicates that read ahead should be terminated immediately a new
command arrives, except in the case when the new command is on the current head and track.
Maximum Pre-fetch specifies the maximum number of LBA's to read ahead after a read command. This
field can either be used as an absolute value, if the MF bit is 0, or else it will be multiplied by the read
command length to give the actual length to read ahead.
Maximum Pre-fetch ceiling specifies the maximum number of blocks the drive should attempt to read
ahead. It is particularly relevant when the MF bit is set.
Number of Cache Segments This field is used to indicate to the drive how many segments are requested
by the initiator. The target supports following Cache Segment configuration:
Number of Seg-
ments
Segment Size
3 128K
6 64K
