MaxSkip
5
The value of this field specifies the number of times that a host request can
be skipped over (such as when performing queuing optimizations). This pa-
rameter affects only queued commands. Some host operating systems sup-
port tagged command queuing which allows for multiple requests to be
resident in the disk drive simultaneously. The disk drive can then re-order
execution of the requests to improve throughput. For systems in which min-
imum completion time of a request is more important than throughput, Max-
Skip can be reduced. Values allowed range from 0 to 255.

Slots to be
Reserved
0
This field is used to reserve x amount of slots from the total resources with-
in the disk drive for incoming commands. Once the remaining slots are full,
up to the queue depth of the disk drive, subsequent commands will be ac-
cepted but placed on a disk drive internal pending list. As the disk drive
completes the active commands, freeing up internal resources (SMBs), the
pending commands are activated.

The value of this field specifies the time, in minutes, of the interval between

checked at five-minute intervals. If the value is set to 60 or greater, the spin-
dle is checked at 60-minute intervals.
