Storage Efficiency Requires Both Hardware and Software Approaches Storage Hardware • Delivers increased storage density and better  software performance to maximize capacity utilization

Storage Software • Delivers storage virtualization, data reduction, and data protection that minimize data capacity, footprint, and management needs

Native Capabilities • 100% organic suite of capabilities, many of  which come as a standard part of every NetApp® system, without extra license costs

Benefits of Thin Provisioning 

Initial storage cost is reduced  Volume can autogrow based on thresholds  Cross-system configuration using Provisioning Manager   Storage on demand program provides pay as you power on • Storage on demand addresses fear of not having needed storage on hand

Efficient Snapshot Copies •Snapshot copies consume minimal storage space, since only changes to the active file system are written, unlike other  Snapshot™  Snapshot™  Copies

approaches that require at least double the storage space. •With NetApp, data is protected by Snapshot copies without the

requirement to purchase excessive amounts of disk storage.
