This section provides an example of a Resource Orchestrator system configuration.
Figure 1.8 Example of System Configuration
Admin Server
The admin server is a server used to manage several managed servers.
The admin server operates in a Windows or Linux environment. An admin server can be operated on VMware and Hyper-V virtual machines.
The Resource Orchestrator manager should be installed on the admin server. The admin server can be made redundant by using clustering software. It can also be standardized with the admin client.
The Resource Orchestrator agent cannot be installed on the admin server to monitor and manage the admin server itself.
Note
Also install ServerView Virtual-IO Manager when creating physical L-Servers using blade servers.
When operating an admin server on a virtual machine on VMware or Hyper-V, do not register VM hosts that operate on the admin server in VM pools.
[VMware]
To use VMware ESXi, install ServerView Operations Manager and register the target VMware ESXi.
[Hyper-V]
When using Hyper-V on managed servers, the only supported OS of the admin server is Windows.
[Xen]
When using RHEL5-Xen on managed servers, the only supported OS of the admin server is Linux.
Managed Server
Managed servers are the servers used to run applications. They are managed by the admin server.
Install agents on managed servers.
In server virtualization environments, the agent should only be installed on the VM host.
Note
When using VMware ESXi, Resource Orchestrator agents cannot be installed.
Install ServerView ESXi CIM Provider agents.
When using other vendor's servers, perform "Configuration when Creating a Virtual L-Server Using VMware ESXi on Other Vendor's Servers".
Admin Client
Admin clients are terminals used to connect to the admin server, which can be used to monitor and control the configuration and status of the entire system.
Admin clients should run in a Windows environment.
Storage Management Server
A server on which storage management software that manages multiple storage units has been installed.
Sharing with the admin server differs depending on the storage in use.
When using ETERNUS storage
Operate ETERNUS SF Storage Cruiser in the same environments as the admin server.
Note that resources for both the admin and storage management software servers are required when operating the servers together.
Operate the ETERNUS SF AdvancedCopy Manager Copy Control Module in the same environment as the admin server.
When using NetApp storage
In Resource Orchestrator, Data ONTAP can be used as storage management software, but a server for storage management software is not necessary, as Data ONTAP is an OS for NetApp storage.
When using EMC CLARiiON storage
In Resource Orchestrator, Navisphere can be used as storage management software, but servers for storage management software are not necessary, as Navisphere is software operated on the SP of EMC CLARiiON storage.
When using EMC Symmetrix DMX storage or EMC Symmetrix VMAX storage
In Resource Orchestrator, Solutions Enabler can be used as storage management software. Servers for storage management software can be operated on the same computer as the admin server, but the storage management software must be connected to EMC Symmetrix DMX storage or EMC Symmetrix VMAX storage using FC-HBA. Note that resources for both the admin and storage management software servers are required when operating the servers together.
VM Management Server
A server on which VM management software (such as VMware vCenter Server, System Center Virtual Machine Manager, and Oracle VM Manager) to integrate multiple server virtualization software products has been installed. The VM management server can be operated on the same machine as the admin server.
Note that resources for both the admin and VM management servers are required when operating the servers together.
PXE Boot Server
For purposes such as OS installation, it is necessary to perform PXE boot of a physical L-Server using its own PXE server.
The PXE boot server must be operated on a server other than the admin server.
Note
PXE boot is unavailable on networks that use tagged VLAN settings.
Do not configure tagged VLANs for PXE boot servers.
HBA address rename Setup Service Server
A server on which the HBA address rename setup service operates.
This is necessary when creating physical L-Servers using rack mount servers.
This is not necessary when creating physical L-Servers using blade servers.
When an admin server cannot be communicated with from a managed server, configure the necessary WWNs for starting the managed server instead of the admin server.
The HBA address rename server operates in a Windows or Linux environment.
Install the HBA address rename setup service online this server.
Use as an admin server and managed server at the same time is not possible.
Keep this server powered ON at all times, in preparation for admin server trouble or communication errors.
For details, refer to "4.3.1.3 HBA and Storage Device Settings" and "C.2 WWN Allocation Order during HBA address rename Configuration".
Admin LAN
The admin LAN is the LAN used by the admin server to control managed servers and storage.
The admin LAN is set up separately from the public LAN used by applications on managed servers.
Using network redundancy software on the server enables redundancy for the admin LAN or the public LAN. Manually configure network redundancy software.
When using a physical L-Server, the default physical network adapter numbers available for the admin LAN are as given below.
When not performing redundancy, "1" is available
When performing redundancy, "1" and "2" are available
Note
When using a NIC other than the default one, the configuration at the time of physical server registration and at L-Server creation must be the same. Thus when designing systems it is recommended that physical servers registered in the same server pool use the same NIC index.
Information
The first NIC that is available for the admin LAN can be changed.
For details, refer to "2.4.2 Registering Blade Servers" of the "User's Guide for Infrastructure Administrators (Resource Management) CE".
