If you assign ports to each resource group without sharing, performance can be maintained on a different port even if the bulk of I/O is issued from one side port.

The following shows a system configuration example of an in-house system division providing the virtual private storage system for two divisions. Divisions A and B each use individual assigned ports and parity groups. In this example, they do not share a port.

The Security Administrator in the system division creates resource groups for each division in the storage system and assigns them to the respective divisions. The Storage Administrator in Division A can manage the resource groups for Division A but cannot access the resource groups for Division B. In the same manner, the Storage Administrator in Division B can manage the resource groups for Division B but cannot access the resource groups for Division A.

Configuration workflow for resource groups not sharing a port

1. The system division forms a plan about creating resource groups and the assigning resources to the groups.
2. The Security Administrator creates the resource groups.
3. The Security Administrator creates the user groups.
4. The Security Administrator assigns the resource groups to user groups.
5. The Storage Administrator in the system division sets ports.
6. The Security Administrator assigns resources to the resource groups.
7. The Security Administrator assigns each Storage Administrator to each user group.

After the above procedures, the Storage Administrators in Divisions A and B can access the resource groups allocated to their own division.
