Note: This hot swap operation requires BIOS and OS support.
Hot Swap Operation
Dynamic hot swap (e.g., surprise removal) is not supported by the SATA host controller. However,
using the SPC register configuration bits, and power management flows, a device can be powered
down by software, and the port can then be powered off, allowing removal and insertion of a new
device.
Intel
ICH5R Only)
The Intel
stripping for higher performance (RAID Level 0), alleviating disk bottlenecks by taking advantage
of the dual independent SATA controllers integrated in the ICH5R. There is no loss of PCI
resources
(request/grant pair) or add-in card slot.
Intel RAID Technology functionality requires the following items:
Intel RAID Technology is not available in the following configurations:
Intel
The Intel RAID Technology for SATA Option ROM provides a pre-OS user interface for the Intel
RAID Technology implementation and provides the ability for a Intel RAID Technology volume to
be used as a boot disk as well as to detect any faults in the Intel RAID Technology volume(s)
attached to the Intel RAID controller.
Power Management Operation
Power management of the ICH5 SATA controller and ports will cover operations of the host
controller and the SATA wire.
Power State Mappings
The D0 PCI power management state for device is supported by the ICH5 SATA controller.
SATA devices may also have multiple power states. From parallel ATA, three device states are
supported through ACPI. They are:
1. ICH5R
2. Intel RAID Technology Option ROM must be on the platform
3. Intel
4. Two SATA hard disk drives.
1. The SATA controller in compatible mode.
2. Intel RAID Technology has been disabled - D31:F0:AE bits [7:6] have been cleared
•
D0 – Device is working and instantly available.
