4 e-services! any asset that can be turned into a service for delivery over the net to drive profit, create revenue or generate efficiency

5 always on infrastructure! necessary to support millions and millions of transactions and appliances! ushering in the new age internet data center

19 It s easy for me to upgrade my existing Ethernet to support. I know how to do that and I know it will work. I just don t want another network. Sony America IT Manager customers speak We have three major data centers and using Fibre Channel SANs and gateways to TCP/IP is just too complex. We ve been slow to adopt FC because it hasn t worked well. We think the company that can provide native IP in the next 12 to 18 months will have a tremendous advantage.

22 Storage is the killer app for Networking Steve DuPlessie Senior Analyst Enterprise Storage Group analysts speak Do we really need a second local area network (LAN) technology and infrastructure simply to support server- to- device data traffic? We believe (IP ) will supplant Fibre- Channel (FC)-based SANs as the primary conduit for enterprise data traffic in the next five years. Stan Schatt Colin Rankine Giga While the benefits of network remain unmistakable, the cost and complexity of fibre channel have left many exploring the viability of less costly and easier to manage native IP- based SAN solutions.
