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."
The Cassatt Collage software currently runs on Linux, Solaris and Windows. Intel, AMD and SPARC processors are all currently supported. You can manage all these kinds of servers within a single-shared environment.

It's very similar to clustered J2EE application servers. With standard J2EE clustering you can group several machines together that all run a single application and spread clients between those systems though a round-robin approach(usually with sticky session) or new clients could be sent to the machine that is the least utilized. Currently with J2EE application server there isn't a whole lot of support for fine tuning client distribution with you own (performance/utilization) load balancing rules. That's where this software comes in, it looks like it adds in extra clustering features to Application Servers like BEA that can already be clustered(BEA is the only one supported at this point). I have nothing to do with these people, I'm a Java instructor and I spent 3 minutes looking at Cassatt's website. There seem to be some software cost justifications there too for those of you asking why it costs so much.

Cassatt isn't a "Java Company." We make a product that helps people run data centers more effiently. We just introduced an extension to the product that makes it work really well with J2EE servers. However, our products also work with Microsoft technologies, and lots of our customers run Windows. No conflict there.
Side note: our internal IT and development systems are managed by our own product. We eat our own dog food.
