Exactly. It's a beautiful concept: the server is roughly half the TCO per gigabyte. That can decrease significantly with better architectures, as shown by this.

Exactly. It's a beautiful concept: the server is roughly half the TCO per gigabyte. That can decrease significantly with better architectures, as shown by this. But making it 2x1GbE is a huge complicating factor. And 2.5GbE is way out of the cost curve per bps.
