-- Said there will be competition of NAS vs. SAN when it comes down to the middle ground, where the issue is "talking with applications (servers)". Will one use TCP/IP (NAS) or Fibre Channel (SAN) here. Robert, I still have to listen to the presentation, but there currently is competition between NAS and SANs. The basic difference is that with NAS you access storage through the LAN, with SANs you do not. It really doesn't matter what communication protocol you are using on the LAN side (TCP/IP). Fibre Channel SANs are hooked up on the other side of things and are not using the network protocol. In fact, many NAS applications use FC controllers and disks. It seems to me that the more critical factors will be: 1. How much traffic do you want to get off your LAN? 2. What are the nature of your applications and what are the traffic characteristics of your network? 3. How much scalability do you need? The rest of your summary is a testament to magnetic storage (it is so inexpensive and effective it will be with us for a long time) and the concept that the bottleneck in the network increases with distance from the processor (in this case the disk or tape). For those interested, I recommend the Unisys site where they also are selling open FC and NAS systems. George
