Thin provisioning is becoming very popular as it offers substantial savings in costs and time resources. It is also positioned to solve the complexity of current storage infrastructures. Not all applications are suitable for thin provisioning (see Thin provisioning: Look before you leap) and new challenges are expected as we move forward. Nonetheless, as this technology becomes more widely adopted and new adjacent technologies emerge, those challenges will prevail and make thinly provisioned volumes the only way to allocate storage. Customers should begin to understand the benefits of thin provisioning for both file and block-based storage and apply the technology where sensible for dramatic productivity improvements and simplification of storage.
