Usb 2.0 Support; Sata Support; Sata Raid; Intel Rapid Recover Technology (Intel Rrt) - Intel DQ57TM Product Manual

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
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
The board incorporates Intel
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.
