Product Description 1.8 USB The board supports up to twelve USB 2.0 ports through two EHCI host controllers on the PCH that allow the use of EHCI-compatible drivers. The port arrangement is as follows: • Four ports are implemented with stacked back panel connectors • Eight front panel ports are implemented through four dual-port internal headers; one header supports an Intel Z-U130 USB Solid-State Drive (or compatible device) For information about The location of the USB connectors on the back panel The location of the front panel USB headers Refer to Figure 10, page 44 Figure 11, page 45 1.9 SATA Interfaces The board provides four SATA connectors through the PCH, which support one device per connector. The PCH provides independent SATA ports with a theoretical maximum transfer rate of 3 Gb/s per port. A point-to-point interface is used for host to device connections. The underlying SATA functionality is transparent to the operating system. The SATA controller can operate in both legacy and native modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI Conventional bus resource steering is used. Native mode is the preferred mode for configurations using the Windows* XP, Windows Vista*, and Windows 7* operating systems. For more information, see: http://www.serialata.org/. For information about The location of the SATA connectors Refer to Figure 11, page 45 1.9.1.1 Serial ATA RAID The board supports the Intel Rapid Storage Technology (Intel RST) which provides the following RAID (Redundant Array of Independent Drives) levels: • RAID 0 - data striping • RAID 1 - data mirroring • RAID 0+1 (or RAID 10) - data striping and mirroring • RAID 5 - distributed parity 19

1.8
USB
The board supports up to twelve USB 2.0 ports through two EHCI host controllers on
the PCH that allow the use of EHCI-compatible drivers.
The port arrangement is as follows:
•
Four ports are implemented with stacked back panel connectors
•
Eight front panel ports are implemented through four dual-port internal headers;
one header supports an Intel Z-U130 USB Solid-State Drive (or compatible device)
For information about
Refer to
The location of the USB connectors on the back panel
Figure 10, page 44
The location of the front panel USB headers
Figure 11, page 45
1.9
SATA Interfaces
The board provides four SATA connectors through the PCH, which support one device
per connector.
The PCH provides independent SATA ports with a theoretical maximum transfer rate of
3 Gb/s per port.
A point-to-point interface is used for host to device connections.
The underlying SATA functionality is transparent to the operating system.
The SATA
controller can operate in both legacy and native modes.
In legacy mode, standard IDE
I/O and IRQ resources are assigned (IRQ 14 and 15).
In Native mode, standard PCI
Conventional bus resource steering is used. Native mode is the preferred mode for
configurations using the Windows* XP, Windows Vista*, and Windows 7* operating
systems.

1.9.1.1
Serial ATA RAID
The board supports the Intel Rapid Storage Technology (Intel RST) which provides the
following RAID (Redundant Array of Independent Drives) levels:
•
RAID 0
- data striping
•
RAID 1
- data mirroring
•
RAID 0+1 (or RAID 10)
- data striping and mirroring
•
RAID 5
- distributed parity
