Purescale delivers a high availability, scalable database clustering solution on commodity hardware. PureScale is mainly aimed at OLTP workloads and I believe it delivers on the promise that Oracle RAC has been making for several years and not quite delivering on. It delivers these benefits without the need for applications to be made cluster aware.
I think a lot of companies are looking to their IT to be scalable and flexible these days. Imagine you could buy a small number of commodity servers to run your application(s) on. Then simply add more when you need more resources. Swap servers in easily to help out with the processing load of end of financial year number crunching or the holiday rush on your online store. Pay the licenses fees and running costs when you use extra servers and then easily shut them down and not pay when they are not needed.
I guess this kind of flexibility is (arguably) available as follows:
1) Mainframe with virtualization. This is a great solution for those who have the skill set and budget for it. In my experience many companies are not ready for this. It's also difficult to shut down part of a mainframe!
2) Cloud computing. A great solution if you can "cloud enable" your applications and you trust the cloud service provider (a lot). Again many are not ready for this.
PureScale (especially on Linux / system x as it is available now) can give this kind of flexibility in a much more accessible package.
As part of my job here in Dublin with IBM I'm currently building a 6 node pureScale cluster on systems x with SLES 10. Watch this space for more on this...
...oh yes and please comment if you want to see more.
