"Storewidth promises to forever change the way the world accesses and shares information, transforming the Internet into the reliable, efficient and useful tool we have long hoped it would be."

The Storewidth Industry Conference will feature the longstanding giants of storage and the pioneers of storewidth who will gather for three days to discuss trends and advances in the field. Executives from Novell, Exodus, Network Appliance, EMC, Inktomi, Sun and Veritas will share the stage with Mangosoft, BlueArc, Scale Eight, Nishan Systems, and TrueSAN. In addition to an address by Mangosoft's Scott Davis, keynotes will include EMC's Mike Ruettgers, StorageNetworks' Bill Miller, Eric Schmidt of Novell and Google, Network Appliance's Kevin Brown, and Sun Vice President Janpieter Scheerder.

"The high level of involvement in this conference is evidence of the vast importance these companies place on the storewidth industry and the significant impact it could have on their bottom line," said George Gilder.
