A Fibre Channel PCI-X card is required to connect Xserve RAID to Xserve G5, Xserve, Power Mac G5, or Power Mac G4. A user installable kit is available and contains a Dual Channel 2Gb Fibre Channel PCI-X Host Bus Adapter plus two 2.9-meter Copper Fiber Channel SFP to SFP (small form factor pluggable) interconnect cables. The Fibre Channel PCI-X card is then installed in your computer and the cables are used to connect to the SFP port on Xserve RAID with SFP connectors. The Fibre Channel PCI-X card supports 64-bit/133MHz PCI-X as well as 33, 66, and 100MHz speeds. SFP connectors on the card allow use of copper or optical cabling and provide the capability of directly connecting to Xserve RAID or Fiber Channel switches over long distances up to 500m. The Apple Fibre Channel PCI-X card offers leading performance and compatibility with Mac OS X and Xserve RAID.
