	Demand Read Re-		This field advises the drive on the retention priority to assign data read into the
	tention	0
	tention	0	cache that has also been transferred from the drive to the initiator.
	Priority
	Priority

	Demand Write Re-		This field advises the drive on the retention priority to assign data written into
	tention	0
	Priority	0	the cache that has also been transferred from the cache memory to the medium.
	Priority

	Disable		This field specifies the selective disabling of anticipatory pre-fetch
	Disable	FFFFh	on long transfer lengths. The value in this field is compared to the number of
	Pre-Fetch Transfer	FFFFh	sectors requested by the current READ command. If the number of sectors is
	Pre-Fetch Transfer
	Length		greater the than the value specified, anticipatory pre-fetch is not performed for
			the command. When 0, anticipatory pre-fetch is disabled.
	Minimum	0x100	This field specifies the desired number of sectors to be pre-fetched preceding
	Pre-fetch	0x100	the requested Data.
	Pre-fetch		the requested Data.
	Maximum	0x200	This field specifies the desired amount of total number of sectors to be pre-
	Pre-fetch	0x200	fetched surrounding the requested data.
	Pre-fetch		fetched surrounding the requested data.
	Maximum		Specifies an upper limit on the number of logical blocks computed as the max-
	Maximum		imum pre-fetch. If this number of sectors is greater than the maximum pre-
	Pre-fetch	0x200
	Pre-fetch	0x200	fetch, then the number of logical blocks to pre-fetch is reduced to the value
	Ceiling
	Ceiling		stored in the maximum pre-fetch ceiling field.
			stored in the maximum pre-fetch ceiling field.

	FSW	0	The Force Sequential Write bit. Not supported by the drive.

	LBCSS	TBD	Selects the units of the cache segment Size field. When LBCSS=0, Units are
	LBCSS	TBD	bytes per segment. When LBCSS=1, Units are blocks per segment.

	DRA	0	When set, the device server will not read into cache any logical blocks beyond
	DRA	0	the addressed logical block (s). When not set, the device server may continue to
			read logical blocks beyond the addressed logical block (s).
	VS		The Vendor-Specific bits. Not supported by the drive.

	Number of Cache	variable	Specifies the number of cache segments to divide the cache into. This field is
	Segments	variable	used when the Size bit is 0.
	Segments		used when the Size bit is 0.
	Cache Segment Size	variable	Specifies the cache segment size, in either bytes per segment or blocks per seg-
	Cache Segment Size	variable	ment, depending on the state of the LBCSS bit. This field is used when the Size
			bit is 1
	Non-Cache Segment	0	Not supported by the drive.
	Size	0	Not supported by the drive.
