A Fiber Channel PCI card is required to connect Xserve RAID to Power Mac G4, Macintosh Server G4, or Xserve. 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 Fiber Channel PCI card offers leading performance and compatibility with Mac OS X and Xserve RAID.
