Using the following functions of Resource Orchestrator, high availability systems can be provided smoothly.
L-Server redundancy
L-Server redundancy can be made with Resource Orchestrator.
On physical L-Servers, by specifying a spare server pool, an operating server can be switched to a spare server during server failure.
On virtual L-Servers, settings differ according to the server virtualization software being used.
For details, refer to "14.1.1 L-Server High Availability" in the "Operation Guide CE".
Server switchover when a chassis fails
If a blade chassis in a configuration where Resource Orchestrator manages multiple blade chassis fails, when starting the physical L-Server on a blade chassis that is not damaged, operations can be re-started.
For details, refer to "14.1.2 Blade Chassis High Availability" in the "Operation Guide CE".
When creating VM hosts on physical L-Servers, server switchover can be performed for VM hosts if chassis failure occurs.
For details, refer to "Appendix F Installation of VM Hosts on Physical L-Servers".
Switchover of operating or standby status of storage
For physical L-Servers, realizes the switchover of operating or standby disks (system/data disks) in configurations in which replication of the operating storage volume used by an L-Server to a standby storage volume is configured.
For details on prerequisites, refer to "3.4.2 Storage Chassis High Availability Design".
For details on operation methods, refer to "14.1.3 Storage Chassis High Availability" in the "Operation Guide CE".
Admin server redundancy
Managers can be operated in cluster systems with Resource Orchestrator.
When operating the admin server in a Windows or Linux environment, redundancy for managers is also possible using clustering software.
An admin server can be operated on VMware and Hyper-V virtual machines.
Using redundancy for virtual machines, redundancy for managers is also possible.
For details on operation methods, refer to "14.2 Admin Server High Availability" in the "Operation Guide CE".
Disaster Recovery
A simple and reliable Disaster Recovery environment is provided by exporting and importing the resource configuration information and user definition information (XML files) of Resource Orchestrator.
For details on prerequisites, refer to "3.4.4 Disaster Recovery Design".
For details on installing and operating Disaster Recovery, refer to "Chapter 15 Disaster Recovery" in the "Operation Guide CE".
