As for the OS running under the covers, it wasn't discussed during the launch. One would expect that it's Oracle Enterprise Linux. Wonder about getting OpenSolaris as the host os? I'd expect performance to get a boost. And on the fault tolerance front, Solaris FMA would provide a benefit - the systems are using Sun's X4170 Nehalem-based systems as the compute server building blocks, which are fully supported by FMA.
