The Cubix ERS/FT was a great little system at the time. It really improved availability and performance of my cc:Mail system and cleaned up the data center at the same time. Although not quite as flexible as a modern blade server system, the Cubix ERS should go down in history as a worthy predecessor.
As I considered the possibilities of the new Apple/Intel interconnect technology known as Light Peak, an odd parallel with 10 Gb Ethernet popped into my head. Much of the confusion around Light Peak revolves around connectors, power conduction, and backward-compatibility. Then, like the Grinch, I thought of something I hadn’t before: Why use optical at all? 10 GBASE-T does just fine over twisted pair, and short interconnect distances would reduce power draw to reasonable levels. What if Light Peak was electrical rather than optical?
