unconfigured disks. PERC H730P, H730, H740P, and H840 cards also support the Manage Physical Disk Power task with

• Customized Power Savings Mode — Allows you to customize the power-saving settings. The default values are populated when

you select this power mode. You can select or clear the features you want to enable. You can select Quality of Service (QoS) to

customize power saving on configured drives by setting the Start Time and Time interval to spin up.
