Intel 10 Gigabit AT Ethernet Server Adapter, Руководство пользователя, Страница: 121 / 165

Problem Solution
PCI-X / PCIe.
Multiple Adapters
When configuring a multi-adapter environment, you must upgrade all Intel adapters in the computer to the
latest software.
If the computer has trouble detecting all adapters, consider the following:
l
If you enable Wake on LAN* (WoL) on more than two adapters, the Wake on LAN feature may over-
draw your system’s auxiliary power supply, resulting in the inability to boot the system and other unpre-
dictable problems. For multiple desktop/management adapters, it is recommended that you install one
adapter at a time and use the IBAUtil utility (ibautil.exe in \APPS\BOOTAGNT) to disable the WoL fea-
ture on adapters that do not require WoL capabilities. On server adapters, the WoL feature is disabled
by default.
l
Adapters with Intel Boot Agent enabled will require a portion of the limited start up memory for each
adapter enabled. Disable the service on adapters that do not need to boot Pre-Boot Execution Envir-
onment (PXE).
Other Performance Issues
Attaining the best speed requires that many components are operating at peak efficiency. Among them are the
following:
l
Cable quality and length - Do not exceed the maximum recommended length for your cable type.
Shorter lengths often provide better results. Check for loose or damaged connectors. Check the cable
for kinked or damaged sections.
l
Bus speed and traffic - The PCI bus speed accommodates the slowest PCI card installed. Check to
see if you have a card that is slowing down your system.
l
Processor and Memory - Check your performance monitoring programs to see if traffic is being
affected by your processor speed, available memory or other processes.
l
Transmission frame size - Your network performance may be enhanced by adjusting or maximizing
the transmission frame size. Operating systems, switches and adapters will impose varying limits on
maximum frame size. See the discussion on Jumbo Frames for your OS.
l
Operating System - Networking feature implementation will vary by operating system version, such
as offloading and multiprocessor threading.
Testing the Adapter
Intel's diagnostic software lets you test the adapter to see if there are problems with the adapter hardware, the
cabling, or the network connection.
Testing from Windows
Intel PROSet allows you to run four types of diagnostic tests.
