Java Virtualization for Server Consolidation

Steve Wilson writes "Cassatt Corporation has released new software that enables administrators with large J2EE farms to much more efficiently use their resources. In order to do this, it leverages the virtualization capabilities inherent in the JVM to create a single shared pool of hardware resources which which all J2EE applications can draw."

Just an FYI for those of you who just joined us. Steve Wilson was the co-author of Java Platform Performance, along with Jeff Kesselman (the Java gaming dude, who still works at Sun). So he's pretty well versed in how Java technology works.

Now on to my own question. :-)

Steve, the one thing I'm not getting from the article, nor from the website (at least, I haven't seen it yet) is as follows: Is this just another DRMAA implementation, or is it more than that? If it is, could you give us a good overview of why it's better than N1? If not, can you explain what exactly this software does for a company? It somewhat sounds like it makes a single JVM run across multiple machines as if they were one, but if that's the case, how does it work? Is it a customized JVM based on Sun source code?

Thanks in advance!
