The PRIMECLUSTER core component, Cluster Foundation (CF), provides the basic cluster services on which all other components are built. CF includes:
Cluster Admin
Supplies the interface for cluster configuration, administration, operation, and diagnostics services.
Web-Based Admin View
Provides a framework under which all the PRIMECLUSTER GUIs, including Cluster Admin, run.
Cluster Resource Management (CRM)
CRM conducts management of resource database that is synchronous in between each cluster nodes. Cluster resource database is a database exclusive for PRIMECLUSTER products.
PRIMECLUSTER SF
Provides a function to guarantee the shutdown of other nodes.
The optional components and products are as follows:
Reliant Monitor Services (RMS)
Manages high-availability switchover (failover) of application processes and their resources.
RMS Wizard Tools is mutually exclusive with respect to installation and operation.
Parallel Application Services (PAS)
Provides a high-performance, low-latency communication facility that can be used by applications.
GDS
Provides the volume management component that improves the availability and manageability of disk-stored data. Without using GDS, failover to the standby system is performed when the resource of the cluster application has an error due to the disk access error, not when the disk access error occurs. For this reason, failover to the standby system takes much time. Specifying the error location also requires much time.
GFS
Provides a file system that can be accessed from two or more nodes to which a shared disk unit is connected. (Only in Oracle Solaris 10 environment)
GLS
Enables high reliability communications through the use of multiple network interface cards to create multiple redundant paths to a local system. Without introducing GLS, the following functions are disabled: configuring the redundant network, using VLAN, and monitoring the standby node.
