Re: a big bottleneck forming is getting information off the storage appliance back to the client....Can rambus play any role here? This is where PC133 and DDR are getting most or all of the server design wins. For a server you need lots of memory to cache as much of the disk activity as possible. Rambus is too expensive, not dense enough (it fits half as much RAM per module as other types), and puts out too much heat to be suitable for machines where if 4 gig of RAM is good, 8 gig is better.

John, I'm not an expert in the SAN/NAS market, but my guess would be that the bottleneck will be the network connection. A 100Mbs Ethernet network only delivers 12MB per second (at 100% bandwidth usage which I'm sure can't be reached in the real world). Even 1G Ethernet would be 120MB per second. Rambus delivers 1.6GB per second (130x faster and 13x faster, respectively?). A buddy who works in the hard drive business tells me they expect to move to RDRAM for the on-board cache for the hard drive. That'll pick up a part of the DRAM usage. A very small part. Dan is probably correct when he says that (for now, I'd contend) the other memory forms are better suited to the task in order to supply larger caches. Dave
