Primary storage data reduction is a series of steps you can take to reduce the amount of capacity dedicated to Tier 1 storage. The most common techniques are archiving, compression, data deduplication, and the use of intelligent storage systems. Real-time compression devices allow for a 60%-plus reduction of NFS and CIFS data with little to no performance impact. Thin provisioning allows you to allocate as much storage as an application may need, but only consume that storage as it is used.”]
