Storage provisioning is the process of assigning storage, usually in the form of server disk drive space, in order to optimize the performance of a storage area network (SAN).

This has been done by the SAN administrator, and it can be a tedious process. You can configure SAN-attached servers with volumes large enough to meet your needs for the life of the server. On the SAN side of the equation, however, only the physical storage required for server application needs is actually released to the server. As the application / Database needs grow, the SAN can be extends the volume until that volume reaches the configured maximum size.

One of the most important tasks performed by the Storage Administrators is the storage provisioning. Storage provisioning is done in steps, which must be followed in a specific order. The storage must be configured for optimum SAN performance. They receive requests for creating certain number of LUNs with certain size and certain RAID configuration. And the next step would be to present those Logical unit numbers (LUNs) to specific hosts and create volumes on those LUNs.


The administrator must be certain that the data storage and recovery routes will be available to all users when needed. Alternate routes must be put in place that can keep the SAN functional in the event of partial failure. Once volumes are created, the next step with be to create or expand file systems. But the initial step in all this process is creating the LUNs. The administrator must make sure that the SAN can accommodate expected future expansion. After everything has been connected and all the programs have been installed, the entire SAN must be tested before sensitive and valuable data is committed to it.
