Business Editors/Technology Writers
BOTHELL, Wash.--(BUSINESS WIRE)--Sept. 13, 2000--Vixel Corporation(Nasdaq:VIXL) announced today that it has been awarded a United States Patent relating to its private loop switching technology.
U.S. Patent No. 6,118,776, entitled "Methods and Apparatus for Fibre Channel Interconnection of Private Loop Devices," defines a number of ways to interconnect private loop devices with a Fibre Channel switch.
Fibre Channel standards define multiple topologies including point to point, arbitrated loop and full fabric, but virtually all of the initial and current deployments of the technology use point to point or the loop topology. Since arbitrated loop is less complex to deploy and manage than a full fabric topology, many computer systems vendors
only support arbitrated loop implementations. Support for full fabric is now just beginning to be deployed. "The technology was conceived by the requirement of end users to maintain the simplicity of the loop and at the same time enjoy the benefits of switch functions," commented Stuart Berman, Vixel's Chief Technology Officer and the patent's author. "The patent defines ways to interconnect devices
through a switch without the complexities of full fabric services support. Because of the simplicity of interconnection that this technology provides, private loop switching is utilized in a majority of both new and existing Storage Area Network (SAN) installations."
"We are delighted to have received recognition from the United States Patent Office on key technology we initially pioneered," commented Jim McCluney, Vixel's President and CEO. "This patent, the first of several additional pending patents, highlights Vixel's industry leading Fibre Channel switch technology. Private loop switching technology has been implemented in Vixel's complete line of fabric products and was key in establishing Vixel as the leading
switch provider to the digital video marketplace."
Using this technology, Vixel has developed a switch product family that provides users with a cost-effective alternative that provides the ease of use of arbitrated loops and the high performance of switching environments. As SANs expand, users can easily migrate the private loop switching environments to full fabric services by a
simple firmware upgrade.
