SAN JOSE, Calif., -- May 21, 1999 -- Cisco Systems, Inc. (NASDAQ:CSCO) today announced it has become a promoter in the Future I/O Alliance, an industry consortium for creating new input/output (I/O) standards for server-to-server and server-to-storage communications. Other Future I/O promoters include Compaq, Hewlett-Packard, IBM, 3Com and Adaptec. The Alliance's goal is to develop open standards that will help enterprises and service providers scale application servers to handle increasing traffic from electronic business and Internet customers. The standards address key issues of improving reliability, availability, and scalability over current I/O networking technologies.

"We are excited about the potential of the Future I/O standards to integrate the best of I/O and data networking," said Frank Maly, director of marketing for Cisco's InterWorks Business Division. "Future I/O is more than just a PCI replacement. It is designed to interconnect servers, I/O devices, and efficiently connect to existing IP networks for client and remote I/O access. We look forward to using our internetworking skills to further develop the Future I/O specifications."

Future I/O Developers Forum

The next Future I/O Developers Forum will be held on May 25, 1999, in Santa Clara to share the progress of the Future I/O specification. The final Future I/O specification will be released later this year.
