As part of Sun’s Datacenter and new multi-core servers they have released LDOM’s (Logical Domains) which pair well with Solaris Zone’s. As with any new technology it’s nice to have functional assessments. Sun has posted the above linked blueprint which details overall sever capacity and functionality when using virtualization. Virtual is the current buzzword, but at the same time you are getting more cpu’s and really more cores per cpu so there is a lot of processing power. The old belief of one application per physical box needs to change. As the blueprint shows when using an application like tomcat there is a real advantage to running more copies of tomcat with a smaller dedicated amount of cpu and memory then to run one large instance of Tomcat. As many applications and languages are not core capable so putting them in virtual servers make it more compatible and better performance. Now I don’t want to give away the big results but the pdf is worth reading as they are able to almost double TPS with their web based application on a single server.

Good to keep in mind before buying your next application server.
