cybrthng asks: "With all of the choices from Gig-E, 10 Gig-E, SCI/Infiniband and other connections for grid database applications, which one is actually worth the money and which ones are overkill or under performing? In a Real Application Cluster (RAC), latency can be an issue with cached memory and latches going over the interconnect. I don't want to recommend an architecture that doesn't achieve desired results, but on the flipside, I don't necessarily want overkill. Sun had recommended SCI, Oracle has said Gig-E and other vendors have said 10 Gig-E. Seems sales commissions drive many of what people recommend, so I'm interested in any real world experience you may have. Obviously, Gig-E is more affordable from a hardware perspective but does this come at a cost of application availability and performance to the end users? What has been your success or failures of grid interconnects?"
You must realize that the computer has it in for you. The irrefutable
proof of this is that the computer always does what you tell it to do.
