You can divide a provisioned storage system into resource groups that enable you to manage the storage system as multiple virtual private storage systems. The storage administrator in each resource group can access only their assigned resources. The following resources can be assigned to resource groups:
- LDEV IDs
Before you create LDEVs, you can reserve the desired number of LDEV IDs and assign them to a resource group for future use. You can also reserve and assign host group IDs and iSCSI target IDs in advance because the number of host groups or iSCSI targets per port is limited.
- DDP groups
- External volumes
- Ports
- Host group IDs
- iSCSI target IDs
- Pools
If you want to limit the capacity that can be used by each user, do not share DDP groups, external volumes, or pools. When DDP groups, external volumes, or pools are shared between multiple users, if one user uses too much capacity of a shared resource, the other users might not be able to perform operations on the storage system.
You can perform resource group operations using the following user interfaces:
- CCI
- CCI embedded
- REST API
