Learn About Creating Storage Partitions

After you have organized your total storage capacity into , you must consider how to share those logical drives among in the . Hosts with different operating systems, called , can share access to a storage subsystem through the use of storage partitioning.

Storage Partitioning is a of the storage management software. Either you or your storage vendor must activate it. The maximum number of storage partitions that you can create on the storage subsystem depends on which premium feature was activated.

A storage partition is a logical entity that consists of one or more storage subsystem logical drives that can be shared among hosts. These entities might be part of a host group or might be accessed by a single host. A storage partition is created when you define a collection of hosts, a , or a single host and then define a . This mapping lets you define what host group or host has access to a particular logical drive in your storage subsystem.

Benefits of using storage partitions include ease of management, amortization of costs, scalability, and flexibility.

Storage Partition Icon

The Storage Partition icon, when present in the Topology pane, indicates that a storage partition has been defined for a host group or a host. This icon also appears in the status bar of the Mappings tab when storage partitions are enabled.

Defining Storage Partitions
  1. Create logical drives on the storage subsystem. During logical drive creation, specify one of two mapping settings:

  2. Define the storage partition , including host groups, hosts, and host ports that access the logical drives. For more information, refer to the Learn About Defining Storage Partition Topology online help topic.
  3. Grant logical drive access to defined host groups or hosts by defining 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 access either of these particular logical drives:
