About Provisioning Storage
In a simple storage configuration, all data hosts could share all available storage in one storage pool, and any host mapped to an initiator would have access to any storage in the pool. Your organization's needs determine whether you want a more complex storage configuration. For example, you might provision the storage for your organization by creating host groups and pools of virtual storage.
The Sun StorEdge 6130 array has a number of physical and logical storage elements that you can use to provision your storage:
- Physical storage elements: initiators, hosts, host groups, trays, and disks
- Logical storage elements: volumes, virtual disks, and pools
Before you can allocate storage appropriately, consider the following requirements for your site:
- Security - By creating host groups, you segregate initiators. For example, the hosts that handle financial data store their data in a different host group from the host group consisting of hosts that handle research data.
- Input/output (I/O) - Some storage profiles specify a general, balanced access to storage, but some parts of your organization might require one or more of the characteristics to be optimized at the expense of other attributes. The array management software includes a set of profiles to meet various needs. You can also create custom profiles.
