I/O adapters (HBA) for servers are shipped with an assigned physical address that is unique across the world. This World Wide Name (WWN) is used by the storage network to identify servers. Until now, the WWN settings on storage networks needed to be updated whenever servers were added, replaced, or switched over. Resource Orchestrator uses I/O virtualization technology that makes server-side I/O control possible. It does this by replacing physically-bound WWNs with virtual WWNs assigned to each server based on its role in the system. Resource Orchestrator can handle different I/O virtualization technologies (VIOM, ISM, and HBA address rename).
With VIOM or ISM, the ability to re-define MAC addresses of network interfaces, boot configuration, and network configuration means that it is no longer necessary to reconfigure network devices or applications that depend on MAC address values.
Note
The "I/O virtualization option" is required when using HBA address rename.
ServerView Virtual-IO Manager should be installed on the admin server when integrating Resource Orchestrator with VIOM.
When coordinating with ISM, install the ServerView Infrastructure Manager virtual appliance on a server other than the admin server.
