This IBM Redpaper describes how to provision storage efficiently with IBM System Storage N series in a Fibre Channel or iSCSI deployment. Storage efficiency has historically been extremely low because of the difficulty provisioning or changing provisioning to adapt to changing needs with classic storage array architectures. System Storage N series with FlexVol™ technology provides an extremely flexible paradigm for provisioning, allowing the user to minimize unused space.

NOTE: This paper does not discuss thin provisioning using LUN and FlexClone.
