USB 3.0 Ports on Intel Sandy Bridge Motherboards and Operating System Installation

On the Intel Sandy Bridge motherboards including the Intel DH61BE motherboard I have noticed that keyboards and mice do not function when they are plugged into USB 3.0 ports when installing an operating system. The USB 3.0 ports are the blue USB ports. I also noticed while installing an operating system with these intel motherboards while the hard drive is plugged into a blue SATA port that the OS installation CD will not recognize that you have a hard drive present. If you have a USB keyboard and or USB mouse plugged into the USB 3.0 port which is the BLUE USB ports during the installation of an operating system, the keyboard and mouse will not function thus preventing you from installing an operating system. This is due to the fact that USB 3.0 functionality is being provided by a separate computer chip on the motherboard versus the legacy USB chip that is built in – integrated into the motherboard for the old school USB 2.0.

This means when installing an OS to ignore the blue USB and SATA ports on these intel motherboard and plug your hard drive and USB keyboard and mouse into the black ports. After you get the OS installed you can switch to using the USB 3.0 ports if you really want to but this isn’t necessary. Once the operating system is completely installed then the USB 3.0 ports will function.

SOURCES OF SERVER AND NETWORK DOWNTIME

Unplanned server and network downtime can be caused by a number of different events:

• Catastrophic server failures caused by memory, processor or motherboard
failures

• Server component failures including power supplies, fans, internal disks,
disk controllers, host bus adapters and network adapters

• Software failures of the operating system, middleware or application

• Site problems such as power failures, network disruptions, fire, flooding or
natural disasters

To protect critical applications from downtime, you need to take steps to protect
against each potential source of downtime.

Eliminating potential single points of failure is a time-tested technical strategy for reducing the
risk of downtime and data loss. Typically, network administrators do this by introducing redundancy in
the application delivery infrastructure, and automating the process of monitoring and
correcting faults to ensure rapid response to problems as they arise. Most leading
companies adopting best practices for protecting critical applications and data also
look at the potential for the failure of an entire site, establishing redundant systems at
an alternative site to protect against site-wide disasters.
