Apple has bundled Xserve Workgroup Clusters with over 200 bioinformatics applications. Apple claims you don't need to be a computer scientist; any scientist could have the workgroup up and running in 30 minutes, and then, back to your real job--performing research.
If you should outgrow your cluster, how do you expand? Easy. Simply place another Xserve into your rack and connect it to the network. It automatically copies the required software and configuration files. With the press of a button, your server reboots and joins the cluster.
What's more, Apple is also having success gaining entry to telecom firms. This article reports that Xserve's ability to efficiently stream Quicktime along with its added support for NTT DoCoMo's 3rd Generation Partnership Project (3GPP) has prompted purchases of Xserve.
Xserve comes loaded with Apache and a host of other tools and services--it's an infrastructure platform. Layered on top of this platform, Apple is adding capabilities that target specific markets, which makes Xserve even more attractive.
