Staggered Disk Spin-Up

Because of the high density of disk drives that can be attached to the Intel® C620 onboard AHCI SATA
controller and the sSATA controller, the combined startup power demand surge for all drives at once can be

Table 38. SATA and sSATA controller feature support

Description
Allows the device to reorder commands for more
efficient data transfers
Collapses a DMA Setup then DMA Activate sequence
into a DMA Setup only
Allows for device detection without power being applied
and ability to connect and disconnect devices without
prior notification to the system
Provides a recovery from a loss of signal or establishing
communication after hot plug
Capable of data transfers up to 6 Gb/s
A mechanism for a device to send a notification to the
host that the device requires attention
Capability for the host controller or device to request
Partial and Slumber interface power states
Enables the host the ability to spin up hard drives
sequentially to prevent power load problems on boot
Reduces interrupt and completion overhead by allowing
a specified number of commands to complete and then
generating an interrupt to process the commands
