Optional Features The whole process (take over of tasks for the other Nodes) is classed as a Failover by Microsoft. Figure A-2. Microsoft Clustering Furthermore, applications can operate on various Nodes, ensuring that all available resources are used to the optimum. An application can not run on both Nodes at the same time (Load Balancing). Microsoft therefore defined this as Static Load Balancing, for example, a static distribution of resources. Dynamic load balancing is not possible at the moment. A speed advantage is only possible if, for example, two different applications are running in parallel on different Nodes of a cluster server (for example, a Web Server on Node 1 and an SQL database server on Node 2). Both Nodes can communicate with each other via the normal network (User LAN). It is possible to link the Nodes with an additional network (Private Network). Microsoft urges the user to use two Interconnects (1 Public Network as User LAN and a Private Network for the Nodes) for OEMs with original MSCS equipment. The diagram on the previous page shows this kind of configuration. A software RAID solution (for example, the NT build-in) is not supported. Therefore, data that is on the hard disks of the shared storage bus must be protected by hardware RAID controllers. Microsoft recommends using suitable hardware RAID controllers for protecting data. It is important for these controllers that the RAID configuration data is stored on the disks and not in an NVRAM. This guarantees that even if a controller fails, or after a controller has been exchanged, the RAID configuration still remains intact. 198 Software Installation and User's Guide
