After you have organized your total storage capacity into logical drives, you must then consider how to share those logical drives among hosts in the storage subsystem. In this release of the storage management software, hosts with different operating systems (heterogeneous hosts
A storage partition is a logical entity consisting of one or more storage subsystem logical drives that can be shared among hosts, which may be part of a host group or accessed by a single host. A storage partition is created when you define a collection of hosts (a host group
Benefits of using storage partitions include ease of management, amortization of costs, scalability, and flexibility.
Important: Storage Partitioning is a premium feature of the storage management software and, therefore, must be enabled either by you or your storage vendor supplier. There is a maximum number of storage partitions that can be created on the storage subsystem depending on the premium feature that has been enabled.
For a tutorial detailing how to use Storage Partitioning, see the Storage Partitioning Tutorial.
The Storage Partition icon , when present in the Topology View, indicates a storage partition has been defined for a host group, or a host. This icon is also displayed in the status bar of the Mappings View window when storage partitions are enabled.
There are three major steps to defining storage partitions:
1 |
Create logical drives on the storage subsystem. During logical drive creation, specify one of two logical drive-to-LUN mapping settings:

2 |
Define the storage partition topology including host groups, hosts, and host ports that access the logical drives. For more information, see Learn About Defining Storage Partition Topology. |

3 |
Grant logical drive access to defined host groups or hosts by defining logical drive-to-LUN mappings, using the Storage Partitioning Wizard. Each host group or host is granted a unique view of partitioned storage and is identified with a storage partition icon A defined host group or host can either access:
