High availability systems can be provided smoothly using the following functions of Resource Orchestrator.
L-Server redundancy
L-Server redundancy is possible with Resource Orchestrator.
On physical L-Servers, by specifying a spare server pool, an operating server can be switched to a spare server when server failure occurs.
On virtual L-Servers, settings differ according to the server virtualization software being used.
For details, refer to "17.1.1 High Availability of L-Servers" 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 "17.1.2 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 D Installing VM Hosts on Physical L-Servers" in the "Setup Guide CE".
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 "7.2 Storage Chassis High Availability Design".
For details on operation methods, refer to "17.1.3 High Availability for Storage Chassis" in the "Operation Guide CE".
In the case of VM hosts, failover of disks from the primary site to the backup site can also be performed by building VM hosts on physical L-Servers.
For details, refer to "Appendix D Installing VM Hosts on Physical L-Servers" in the "Setup 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 "17.2 High Availability for Admin Servers" in the "Operation Guide CE".
Disaster Recovery
Disaster recovery can be done in a simple and reliable way by exporting and importing the following information between managers of Resource Orchestrator.
L-Platform Template
L-Platform Configuration Information
Resource Information
Accounting Information
Metering Log
For details on prerequisites, refer to "Chapter 2 Design" in the "DR Option Instruction".
For details on installing and operating Disaster Recovery, refer to "Chapter 3 Installation" and "Chapter 4 Operation" in the "DR Option Instruction".
