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 Enterprise. 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 that are 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 )
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. Benefits of storage partitioning include ease of management, amortization of costs, scalability, and flexibility. For a tutorial explaining how to set up Storage Partitioning, see Setting up Storage Partitioning, Step-by-Step.
There are three major steps to creating storage partitions:
1 |
Create logical drives on the storage subsystem. During logical drive creation, you can specify one of two logical drive-to-LUN mapping
|
2 |
Then, define Storage Partitions Topology, that is, the host groups, hosts, and host ports that will access the logical drives. |
3 |
Third, grant logical drive access to defined host groups or hosts by defining logical drive-to-LUN mappings. Each host group or host is granted a unique view of partitioned storage. A defined host group or host can either see:
The following example shows that two host groups have been defined (host group Omaha and Kansas City) that have access to various logical drives. In this example, two partitions have been used. The first partition consists of logical drives Financial and Legal and it is accessed by the hosts in host group Kansas City using LUNs 4 and 2, respectively. The second partition consists of logical drives Engineering, Marketing, and H Resources and it is accessed by the hosts in host group Omaha using LUNs 5, 6, and 7, respectively. |
