PRIMECLUSTER Installation and Administration Guide 4.4

1.1 Planning

Before building a PRIMECLUSTER system, you must first design the system.

Designing a PRIMECLUSTER system

1. Select the PRIMECLUSTER products.

   Select the PRIMECLUSTER products required for the system you want to build.

   For details, see "2.1 PRIMECLUSTER Product Selection."

2. Design the system.

   Determine the operation environment for building the PRIMECLUSTER system and whether to use the virtual machine function. This includes selecting the applications to be used and determining the required hardware resources, such as the number of hosts, networks, the number of cluster interconnect paths, and disk size.

   Up to 16 nodes can be added to one cluster system.

   We recommend that you use 2 or more cluster interconnects.

   For details, see "2.2 System Design."

3. Determine the cluster system operation mode.

   Determine the number of nodes and the operation mode of the cluster system.

   For details, see "2.3 Determining the Cluster System Operation Mode."

4. Determine the operation mode for using Web-Based Admin View.

   Determine the operation mode for running Web-Based Admin View. Web-Based Admin View can manage up to 16 nodes.

   For details, see "2.4 Determining the Web-Based Admin View Operation Mode."

5. Determine the cluster applications.

   Determine the number of cluster applications. Also determine which nodes are to be used for each application.

6. Determine the resources required for each cluster application.

   Determine the resources required for each cluster application.

   • Determine the switchover network type (IP address takeover) and the takeover address.

   • Determine whether a user-defined RMS configuration script is to be used. Determine whether there are other items to be used as resources.

   • For a disk device, determine which nodes will be sharing the device, whether the device is to be used as a RAW device (database system), whether the device is to be used as a file system (general files), and whether the device is to be grouped.

7. Determine the failover range of the cluster application.

   Determine the trigger for cluster application failover.

   For details, see "2.5 Determining the failover timing of a cluster application."
