Attributes provided
• NPIV capability is supported through VIOS.
• Requires a PCI Express generation-2 x8 slot for all four ports to operate at full speed.
Cables
Use multimode fiber optic cables with shortwave lasers that adhere to the following specifications:
• OM3: Multimode 50/125 micron fiber, 2000 MHz x km bandwidth
• OM2: Multimode 50/125 micron fiber, 500 MHz x km bandwidth
• OM1: Multimode 62.5/125 micron fiber, 200 MHz x km bandwidth
Because core sizes are different, OM1 cables can only be connected to other OM1 cables. For best
results, OM2 cables should not be connected to OM3 cables. However, if an OM2 cable is connected to an
OM3 cable, the characteristics of the OM2 cable apply to the entire length of the cables. The following
table shows the supported distances for the different fiber optic cable types at different link speeds.

Operating system or partition requirements
If you are installing a new feature, ensure that you have the software that is required to support the new
feature and that you determine whether any prerequisites must be met for this feature and attaching
devices. For information about operating system and partition requirements, see one of the following
topics:
• The latest version of enabling libraries and utilities can be downloaded from Fix Central (http://
www.ibm.com/support/fixcentral/).
• Power Systems Prerequisites (http://www14.software.ibm.com/support/customercare/iprt/home).
• IBM SSIC (System Storage Interoperation Center) (http://www-03.ibm.com/systems/support/storage/
ssic/interoperability.wss).
• The latest version of the device driver or IBM Power RAID adapter utilities (iprutils) can be downloaded
from the IBM Service and Productivity Tools website (http://www14.software.ibm.com/webapp/
set2/sas/f/lopdiags/home.html).
• For support details, see the Linux Alert website (http://www14.software.ibm.com/webapp/set2/sas/f/
