Thin Provisioning

The concept of Thin Provisioning (and space reclamation) is the means by which an OS and its chosen

volume and file management platform interact with the Dell Compellent Storage Center products. In

this interaction, the OS (and volume/file management) communicates via SCSI library calls with the

Dell Compellent Storage Center products and continually monitors the amount of space allocated (from

the Dell Compellent Storage Center) versus the amount of space actually used. In doing so, the LUNs

(as presented to the OS) can appear to be actually larger than the actual allocated (reserved) space on

the Dell Compellent Storage Center. This creates a model of “just-enough” and “just-in-time” storage

allocation, thereby resulting in huge savings both from a capital and operational perspective. For more

information, please refer to this link http://h71028.www7.hp.com/enterprise/us/en/os/hpux11i-fsvm-

overview.html.

HP-UX 11i v2 and older platform versions DOES NOT support Thin Provisioning interoperability with the

Dell Compellent Storage Center products.
