Intel Fiber Optic Adapters
==========================

Caution: The fiber optic ports may utilize Class 1 or Class 1M laser 
devices. Do not stare into the end of a fiber optic connector 
connected to a "live" system.  Do not use optical instruments to 
view the laser output. Using optical instruments increases eye hazard.  
Laser radiation is hazardous and may cause eye injury.  To inspect a 
connector, receptacle or adapter end, be sure that the fiber optic 
device or system is turned off, or the fiber cable is disconnected 
from the "live" system. 

The Intel Gigabit and 10GbE network adapters with fiber optic connections
operate only at their native speed and only at full-duplex.  Therefore
you do not need to make any adjustments.  Use of controls or
adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure.  The laser module 
contains no serviceable parts.  


Saving and Restoring Adapter Settings
=====================================

You can save and then restore adapter settings through the script 
SavResDX.vbs.  Intel PROSet is required for SavResDX.vbs to function 
correctly. The Restore operation requires the same OS as when the 
configuration was Saved.


Intel(R) I/O Acceleration Technology
====================================
Intel I/O Acceleration Technology (Intel(R) I/OAT) is a new Intel 
platform network technology that accelerates, optimizes and seamlessly 
scales enterprise servers on Microsoft Windows Server* and Linux* 
operating systems. Acceleration moves networking data to applications 
faster. Optimization allows you to increase the load on your servers 
without increasing power consumption. Seamless multiple port scaling 
gives you increased networking throughput from teaming along with reliable 
server and application availability.

Intel I/OAT requires the following to operate on Microsoft Windows 
Operating Systems:
 - A server chipset and BIOS that are Intel I/OAT capable 
 - Microsoft Windows Server 2008 or
 - Microsoft Windows Server 2003 with Service Pack 1 or 2 installed
   - The Scalable Networking Pack from Microsoft (this is installed as part
     of Service Pack 2 or Windows Server 2008)
 - An adapter or network connection that is Intel I/OAT-capable 
   - The RSS advanced setting must be enabled
   - Under TCP/IP Offloading Options, both Offload Receive IP Checksum and
     Offload Receive TCP Checksum must be enabled.

Known Issues
------------

  Unexpected reboot on driver update
  ----------------------------------
  If a Direct Cache Access (DCA)-capable device has registered with the 
  QuickData driver to perform DCA, the driver will not unload. When the 
  QuickData driver is updated, the operating system will force a reboot.

  No DMA activity on Intel I/OAT-capable ports
  --------------------------------------------
  At least one Intel I/OAT-capable port must be enabled when your system 
  starts up. If no Intel I/OAT-capable ports are enabled at system startup, 
  the IOATDMA driver will not register with NDIS and Intel I/OAT-capable 
  ports enabled after system startup will show no DMA activity. Enable an 
  Intel I/OAT-capable port and reboot to resolve this issue.

  DMA copies are lower than expected
  ----------------------------------
  Some software applications do not utilize the full range of performance 
  enhancements available with Intel I/OAT. Please check with your software 
  vendor for an updated version.

  CPU utilization is not balanced across all CPUs
  -----------------------------------------------
  CPU and DMA channel load may be unbalanced under the following conditions:
  - The system is using Intel I/OAT, and
  - There are multiple PCI Express LAN ports (both Intel I/OAT-capable or 
    non-Intel I/OAT-capable) in the system, and
  - One or more of the PCI Express ports are not utilized or not enabled 
    for Intel I/OAT
