In 2001, Bechtolsheim caught the entrepreneurial bug again, and he saw the InfiniBand switched fabric as the next place to make some money and have a technological impact. And so he founded another startup called Kealia, which created the "Galaxy" line of Opteron-based blade servers, the "Magnum" monster InfiniBand switch, and the "Thumper" X4500 storage servers that came to market individually after Sun bought Kealia in early 2004 and made Bechtolsheim CTO of its server biz. The original vision that Kealia had, of course, was for an integrated blade and storage platform with an InfiniBand backbone, something Sun is selling as the Constellation System to HPC and media streaming customers.
I believe every sentence in this paragraph is false. Kealia was founded on the idea of DRAM-based video streaming over 10Gb Ethernet, not anything InfiniBand-related. Kealia was responsible for Thumper and did the initial work on Galaxy (though it was not very far along at acquisition) but not Magnum. Andy's title within Sun was not CTO. Kealia was not planning anything remotely similar to the Constellation system; we were simply not targeting the HPC market in 2001, nor even devoting significant resources to it in 2004.
