Clusters for business-critical applications |
| Enterprise business processes running on Intel-based servers deliver real benefits. But as demands and loads increase, maintaining elevated stability and availability can be problematic. Cluster solutions, like the configuring of several servers to form a system network, can help. Fujitsu Siemens Computers has decades of experience with cluster technology and project implementation in mainframe and UNIX environments. High-availability tools such as PRIMERGY MultiPath |  |
| and DuplexDataManager can be combined with Microsoft Windows Cluster Server environments to produce disaster-tolerant configurations. |
|
PRIMERGY DuplexDataManager |
| The PRIMERGY DuplexDataManager permits operation of redundant disk storage subsystems with data mirroring over long distances. By combining these functions with cluster solutions and Fiber Channel technology, remote “shadow” data centers can be created, ensuring permanent IT availability even in the event of a disaster. DuplexDataManager allows the distance and speed benefits of Fibre Channel to be exploited to their fullest. |
|
PRIMERGY MultiPath |
| PRIMERGY MultiPath supports redundant Fiber Channel paths, the configured connections between server and subsystem that are such an important component of disaster-tolerant servers and clusters. It is thus the ideal software for managing and operating these redundant data paths. MultiPath ensures that the communications channel remains constantly available, even when faults occur on one of the connections. The redundant path can be operated passively (on “standby”) or actively, with load balancing to increase data throughput. |
|
Microsoft Cluster Servers |
| The Microsoft Cluster Server configuration consists of two independent Windows-based servers. These are interconnected and appear to the user as a single server system. Network-based clients have full access to all the resources in the cluster, and if one server fails, the other automatically takes over the functions it was performing. |
