Desktop Board Features USB 2.0 Support The board supports up to 12 USB 2.0 ports provided by two EHCI host controllers in the PCH that allow the use of EHCI-compatible drivers. The port arrangement is as follows: • Four back panel connectors • Eight front panel ports implemented as four dual-port internal headers. One of the internal headers supports an Intel Z-U130 USB Solid-state Drive or compatible device. USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer rates. SATA Support 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 computer to storage device connections. SATA RAID The Intel Q57 PCH supports Intel® Rapid Storage Technology (Intel® RST) which enables 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 Intel® Rapid Recover Technology (Intel® RRT) The board incorporates Intel® Rapid Recover Technology (Intel® RRT). Intel RRT is a feature of Intel RST. Intel RRT uses RAID 1 (mirroring) functionality to copy data from a designated master drive to a designated recovery drive. The master drive data can be copied to the recovery drive either continuously or on request. When using the continuous update policy, changes made to the data on the master drive while the recovery drive is disconnected or offline are automatically copied to the recovery drive when it is reconnected. When using the on request update policy, the master drive data can be restored to a previous state by copying the data on the recovery drive back to the master drive. 19

Desktop Board Features

USB 2.0 Support
The board supports up to 12 USB 2.0 ports provided by two EHCI host controllers in
the PCH that allow the use of EHCI-compatible drivers.
The port arrangement is as follows:
Four back panel connectors
Eight front panel ports implemented as four dual-port internal headers.
One of the
internal headers supports an Intel Z-U130 USB Solid-state Drive or compatible
device.
USB 2.0 support requires both an operating system and drivers that fully support
USB 2.0 transfer rates.
SATA Support
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 computer to
storage device connections.
SATA RAID
The Intel Q57 PCH supports Intel
®
Rapid Storage Technology (Intel
®
RST) which
enables 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
Intel
®
Rapid Recover Technology (Intel
®
RRT)
The board incorporates Intel
®
Rapid Recover Technology (Intel
®
RRT).
Intel RRT is a
feature of Intel RST.
Intel RRT uses RAID 1 (mirroring) functionality to copy data from
a designated master drive to a designated recovery drive.
The master drive data can
be copied to the recovery drive either continuously or on request.
When using the continuous update policy, changes made to the data on the master
drive while the recovery drive is disconnected or offline are automatically copied to the
recovery drive when it is reconnected.
When using the on request update policy, the
master drive data can be restored to a previous state by copying the data on the
recovery drive back to the master drive.
