New OVM Server for SPARC WP
By mramcha on Mar 15, 2013
I've been working mainly on Engineered Systems, more specifically SPARC SuperCluster for the past year, and it occurred to me that the way that we use layered virtualisation within the SSC is not very heavily publicised, and although you could derive these configurations from the OVM Server for SPARC documentation, it wasn't clear that this was considered a valid way of configuring a T-Series based server.
One of the ways that the SSC achieves such high levels of performance and efficiency, is that all the domains are built as root domains, which means that there is zero virtualisation overhead within these domains. Implementing Root Domains with Oracle VM Server for SPARC co-written by me, Mikel Manitius and Jeff Savit explains how this is achieved, and how to use these techniques on your own T4 based servers, to get the same kind of benefits.
