Optimizing controller performance for video
On some controller models, you can optimize the controller performance for video.
For this feature to be available, you must install SAAP on the controller and register the SAAP license key.
Syntax:
<target> modify dpo=enable elevatorsort=disable irp=enable
queuedepth=automatic mnpd=60
where the target is any valid controller.
The queuedepth parameter can also have a numerical value from 2 to 32, and the mnpd parameter can
have any value from 0 (disabled) to 60.
To disable the video performance optimization feature, reverse the disable and enable values noted above,
set the queue depth to automatic, and set mnpd to 0, as in the second example command.
Example commands:
=> ctrl slot=5 modify dpo=enable elevatorsort=disable irp=enable
queuedepth=16 mnpd=25
=> ctrl slot=3 modify dpo=disable elevatorsort=enable irp=disable
queuedepth=automatic mnpd=0
Creating a logical drive
Syntax:
<target> create type=ld [parameter=value]
<target> is usually a controller, but it can be an array if you are creating an additional logical drive on an
existing array.
If you want to create a logical drive on a group of physical drives that are not yet assigned to an array, you
do not have to build the array first. In the CLI, unlike in the GUI, the array is created automatically at the same
time as the logical drive.
The standard parameters used when creating a logical drive are described in the following table. If you do
not specify a particular parameter, the CLI uses the appropriate default value.

Comments
The default setting is all.
The default setting is the highest RAID
level that the controller model and
number of drives can support, except
50 or 60 (which must be specified
deliberately).
The default value is 2.
Units are KB.*
The default setting depends on the
RAID level.
This parameter determines the
desired size of the logical drive.
Units are MB.*
The default setting is max.
