PRIMECLUSTER allows a redundant configuration in a virtualization environment and also enables high reliability of the integrated system:
KVM environment
RHOSP environment
VMware environment
Oracle VM Server for SPARC environment
Oracle Solaris Zones environment
Kernel Zone
Non-global Zone
Previously, the cluster system has been built and operated with different servers for each service.
However, it is possible to integrate multiple services to a single server by supporting virtualization environments.
Within a server, CPU resources can be allocated and operated for each service.
Figure 1.4 Existing cluster system and cluster system in a virtualization environment (For example, KVM environment)
By installing PRIMECLUSTER into each host OS and guest OS, you can immediately switch servers in the event of an operating system error as well as an application error.
Figure 1.5 Cluster system in a virtualization environment (For example, KVM environment)
By installing PRIMECLUSTER into the guest OS, you can immediately switch the guest OS when an error occurs in applications or in OS.
Figure 1.6 Cluster system in a virtualization environment (For example, RHOSP environment)
Install PRIMECLUSTER into guest OSes only.
When an error of applications or operating systems occurs, you can safely and securely switch servers if VMware vCenter Server functional cooperation or the I/O fencing function using shared disks is used.

Oracle VM Server for SPARC environment
By installing PRIMECLUSTER into control domain and guest domains, you can immediately switch servers in the event of a guest domain error as well as a partition error.
Figure 1.8 Cluster system in a virtualization environment (For example, Oracle VM Server for SPARC environment)
Oracle Solaris Kernel Zones environment
By installing PRIMECLUSTER into a control domain or a guest domain after creating Kernel Zones in a control domain or a guest domain, you can immediately switch servers in the event of a domain error as well as a partition error.
Figure 1.9 Cluster system in a virtualization environment (For example, Oracle Solaris Kernel Zones environment on Control Domain)
Figure 1.10 Cluster system in a virtualization environment (For example, Oracle Solaris Kernel Zones environment on Guest Domain)
Oracle Solaris Non-global Zones environment
By installing PRIMECLUSTER into the global zone, you can switch each server when an error occurs in the global zone.
Moreover, by installing PRIMECLUSTER into non-global zones, you can switch each non-global zone when an error occurs in applications.
